While all the rain pants we’ve reviewed are excellent choices, the Helium rain pants by Outdoor Research are our clear favorite in the ultra light category. Highly packable, these rain pants take up next to no space up in your backpack, simply fold them into their back pocket which doubles as a stuff sack.
The Helium pants take up much less space than any of the other rain pants listed. They are also extremely light, weighing in at just 5.6oz (160g).
Made from a 100% nylon construction, these rain pants are actually more durable than you would think given their extra light weight. The 30-denier ripstop construction makes them suitable for hiking over a variety of terrains and while you will find more durable rain pants, you won’t find ones any lighter with their level of durability.
It really comes down to where you tend to hike and where you are likely to wear them most. For us, this pair of rain pants represents the ideal tradeoff between lightweight and durability, bearing in mind they will probably spend most of the time getting carried about in your backpack.
The Pertex Shield+, makes these ultra-light rain pants highly waterproof and breathable. This treatment consists of a PU film that is laminated on to the nylon shell, allowing moisture built up on the inside to pass through to the outside, while preventing external moisture from entering the pants. The seams are fully taped, ensuring that you won’t get wet.
When it comes down to fitting, the Helium are comfortable to wear, although they do tend to size small, especially for use over your regular hiking trousers. The fit is on the slimmer side, however, we found that this improved this rain pant’s mobility rating and the fabric has a good motion range.
As for features, the Helium, as pared down ultra-light rain pants, doesn’t offer much in the way of added extras. The elasticated drawstring waistband is comfortable, even with a fully loaded backpack.
The legs feature zippers to enable you to put on and take off the pants without removing your footwear, although the zipper opening can be a little snug for those with larger feet wearing smaller sized pants.
There are also elastic loops for suspenders, reflective logos, a carabiner loop to attach them to your pack and internal loops under the pant cuffs, which allow you to use them like gaiters, keeping out snow and debris.
There is just the one back pocket, however, provided your rain jacket has decent pockets, you won’t really need more pockets in your rain pants. It comes down to personal preference.
All in all, we were highly impressed with the Helium rain pants, if you need a pair of lightweight rain pants to keep in your pack for light to moderate use on average hiking trips, then you really won’t find much better than this.
Highly packable, ultra-light weight, you can simply pack the Helium and forget about them until you need them.
#2 Arc’teryx Beta SL Pant
- Gore-Tex fabric with Packlite Plus technology
- ¼ length WaterTight lower leg side zippers
- SL = superlight range, weight 9.2oz / 260g
- Elasticated waistband with drawcord and fly zipper
- Adjustable, reinforced cuffs with drawcords and lace hooks
- Less breathable than other rain pants
Arc’teryx Beta SL Pants Features Summary:
- Superlight, packable emergency waterproof pant
- Minimalist design maximizes packability
- Reduced weight without sacrificing key features
- For use during sudden storms
- Simple pull-on design
- Full length side zippers for easy on/off and rapid ventilation
- Hem and insteps are reinforced with abrasion-resistant N150p-X GORE-TEX fabric with Paclite® Plus product technology
- Material: GORE-TEX fabric with Paclite® Plus
- Weight: 12.5 oz / 355 g (reg)
Best Uses: Day hiking, trekking, travel, general outdoor use
The Arc’teryx Beta SuperLight Pant has been designed to provide maximum storm protection against the wind and rain in a lightweight, easily packable format.
While these rain pants weigh more than the Helium, they are still an ultra-light model that won’t weigh down your backpack.
For this model with the ¼ length zippers, the weight is a respectable 12.5 oz (355g) making the Beta SL a good lightweight and packable choice to keep in your backpack. The micro-seam allowance helps to keep weight down.
Made from nylon with a Gore-Tex breathable laminate, the Beta SL benefits from having the instep, lower leg and hem reinforced with a heavier weight three-layer Gore-Tex laminate.
This makes the Beta SL a more durable rain pant, hence the slight extra weight. Although the Gore-Tex laminate with Packlite Plus technology is extremely efficient at keeping water and the wind out, it is slightly less breathable than other rain pants.
However, all things considered for your average hiker and when worn as a shell layer, this detracts little from these rain pants’ otherwise excellent performance.
The Beta SL has a fairly baggy fit, which can be preferable when you’re looking to wear it over other clothing. It really comes down to a matter of personal preference.
Available in short, regular and tall lengths, this model has a good range of different lengths for a more customized fit and enhanced comfort. The articulated knees enhance mobility as does the gusseted crotch area.
With the reinforced areas adding to the weight, whilst enhancing the product’s durability, Arc’teryx have chosen to cut back on other features to keep the Beta SL rain pant at a competitive weight and still highly packable.
For this reason, perhaps, this rain pant does not have any pockets, which may or may not be an issue for you. While you can rely predominantly upon your jacket pockets and don’t really need any in your rain pants, it can be a good option to have at least one though.
The lower legs feature ¼ length zippers making the pants easy to put on or remove, while the adjustable cuff drawcords and lace hooks work well, securing the rain pants over your boots and keeping the elements and any debris out. The elasticated waistband is comfortable and has a drawcord and fly zipper access.
All in all, the Beta SL are comfortable and easy to put on in the event of a sudden downpour. Their reinforced areas make it more durable than several others, without compromising too much on weight.
A good compact model that will keep you dry, although at a price that is in fitting with the brand and high quality of the product.
#3 Marmot PreCip Pant
- Lightweight 12oz / 340g
- Full-length zippers – easy put on and venting
- Three zippered pockets
- Elasticated waistband
- Tapered seams and NanoPro waterproof fabric
- Lack Durability
- Less breathable than other pants
Marmot Precip Pants Features Summary:
- Lightweight PreCip full zip pant

- Material: Marmot NanoPro™ fabric
- Weight: 12 oz / 340g
Best Uses: Hiking, trekking, travel, cycling, general outdoor use
The main advantage of the Marmot PreCip Rain Pants is their full-length zippers. Understandably, these also have their downsides, which we’ll take a look at.
In terms of weight, understandably the Marmot Precip is one of our heavier choices, weighing in at 12oz (340g). While it is not the lightest by a long shot, if you are looking for lightweight, packable rain pants and our other picks, don’t quite fit the bill, then this pair could possibly be the ones for you.
In spite of them being a bit heavier, the Marmot Precip are still highly packable and roll up neatly, taking up only a small amount of backpack space. So, is it worth the extra ounces?
Material wise, the Marmot PreCip is 100% nylon. Unfortunately, the fabric itself is on the thin side and appears lacking in durability.
While the pants would be a good, relatively inexpensive option to keep in your backpack for occasional use, when used regularly they probably would not last as long as some of our other top choices. So, it all comes down to your needs and what you expect from your ultra-light rain pants.
The PreCip are treated with Marmot’s own NanoPro waterproofing and all seams are 100% taped. The full-length side zippers have bonded storm flaps, however, bear in mind that where there are zippers there does tend to be some vulnerability to water leaking.
The DWR works well and the pants are waterproof. In terms of breathability, the PreCip performs pretty well, although it is not as breathable as the Helium. Of course, you can use the zippers to vent moisture, however, you’ll risk getting even wetter.
The mesh pockets do, however, provide some extra breathability, if you find you’re working up a sweat.
The PreCip pants are fairly comfortable with a relaxed fit and it is available in standard sizes with a short length option. It generally fits true to size, taking into account that you’ll mostly be wearing it as on over garment.
The elasticated waistband is comfortable, although it would be nice to have a drawcord to tighten the waist a little more. The three mesh, zippered pockets are useful and as stated previously can help increase breathability. The main advantage of this PreCip model is the full-length zippers.
They allow you to quickly and easily put on and take off the rain pants. If you have very large feet or extra wide boots, this could make the extra weight of this model well worth it.
Being able to quickly and easily put on rain pants as the storm breaks is invaluable to staying dry. It is also a good way to keep the worst of the mud and wet on the rain pants when you’re done wearing them, rather than getting it over the rest of your clothes.
On the whole, the Marmot PreCip full-zip pants are a great option. While they are not the lightest weight, they are extremely practical, although durability could be an issue with frequent use. A good value choice that is effective yet inexpensive.

The Ozonic Rain Pants by Mountain Hardwear are one of the most comfortable rain pants available thanks to their in-built stretch. Let’s see how the rest of this rain pant’s specifics bear up.
As far as weight and packability go, the Ozonic weighs in at 10oz (283g), which makes it around average in terms of ultra-light rain pants.
Thanks to its stretchy fabric, it is extremely compressible and will only take up a tiny amount of space in your backpack, making it a great choice for those with limited room to spare.
Made from a 40-denier nylon fabric, the Ozonic is also fairly durable and resistant, making it a better choice for rougher terrain. As it’s stretch fabric tends to hug more closely to your contours, it’s also less likely to get snagged by vegetation or other obstacles.
The Ozonic is treated with a DryQ Active 2.5-layer waterproofing. This waterproofing performs satisfactorily, although possibly less well than the Helium or Beta SL. The storm flaps and watertight zippers help to keep you dry whilst allowing easy access.
This rain pant is extremely comfortable compared to rain pants in general, thanks to its four-way stretch fabric. This allows complete freedom of movement, so if you’re dealing with any ascents or descents, rocky areas or any other challenging terrain in the wet, you won’t be held back by the Ozonic that moves with you, hugging your legs.
This is enhanced further by the inbuilt knee articulation. The webbing waist belt also adds another level of comfort, by enabling you to keep this rain pant well-adjusted in combination with the elasticated back that is comfortable with a fully-loaded backpack.
Other features include full-length zippers that allow you to easily put on and take off the Ozonic quickly, even with large or wide footwear, keeping you cleaner and drier.
Loops at the bottom of the cuff fasten to your boots, keeping you drier and any debris out. There is a thigh height zippered pocket that is good to have, however, not very comfortable for anything but the smallest of items.
A good choice for staying dry on hikes where challenging terrain requires a more athletic performance, the four-way stretch fabric moves with your body.
The full-length zippers and high compressibility also make this rain pant an outstanding choice. However, for extreme wet weather, you may be better off with a slightly better performing membrane.
#5 Mountain Warehouse Pakka Rain Pants
- Lightweight: 5.3oz / 150g
- Compresses into stuff sack
- Hook and loop adjustable ankle opening
- Easy access to hiking trouser pockets through openings
- Very thin fabric
- Not as waterproof in extreme, heavy downpours
Mountain Warehouse Pakka Pants Features Summary:
- 100% Nylon
- Taped Seams
- Hook & Loop adjustable ankle opening
- Packable in drawstring bag
- Material: 100% nylon, with Rainproof ISODRY
Best Uses: Hiking, travel, biking, general outdoor use
The Pakka Rain Pants by Mountain Warehouse are a no nonsense, no frills rain pant that are extremely lightweight and inexpensive. We always like to list a budget option for the occasional hiker or for light recreational use, and the Pakka fit that bill well.
Weighing in at around 5.3oz (150g), they are even lighter than the Helium, although of a lesser quality construction, fit and performance.
The Pakka take up a minimum of space and come with a handy stuff sack to keep the pants neatly compressed in your backpack. It’s also comes in handy for packing it away in when wet after use.
Made from nylon, with an IsoDry fabric treatment, the Pakka are basic, entry-level rain pants and perform accordingly. The fabric is very thin and rather fragile.
Water resistant, rather than waterproof may be a better description, however, in light to moderate rainfall, these rain pants perform well and will keep you dry. They are not particularly breathable, which is to be expected for the price you pay for them.
In terms of comfort, as they are so lightweight, you barely feel that they are there. You can adjust the bottom cuff to fit which can increase comfort levels slightly and helps to keep water and debris out. They fit reasonably well, although they do not move with your body like the Ozonic.
The Pakka rain pants do not have any pockets, although it does have pocket openings that allow you to access your hiking pants pockets underneath.
The elasticated waistband is satisfactory, however the quality of the elastic remains to be seen over time. For the low price, the Pakka are a good buy, but set your expectations accordingly.
While they lack the comfort and features of the other models we’ve reviewed, for infrequent use in damp conditions they serve their purpose well. For any extreme or severe rain, or for more durable rain pants that will last, the Helium or Beta SL are much better options.
For the occasional hiker in a temperate climate, having the Pakka rain pants in your backpack could help you stay dry during the occasional shower for a very low price.
Why You Need Rain Pants
Good, dependable rain pants can make the difference between a good hike and a bad hike. Or even not going out on a hike, if you see the clouds darken and are hesitating.
Knowing you can stop and quickly protect yourself with your rain pants will allow you to enjoy your hikes even more, and they can even be useful for crossing wet fields as well as waterfall hikes, muddy trails and anywhere else you’re likely to risk getting damp.
Rain Pants’ Features
Aside from the obvious such as waterproofing and fastenings, rain pants come with a variety of features, some more essential than others.
The majority of rain pants are typically made from nylon, as it’s lightweight and even before treatment it tends to have excellent water-resistant properties.
You want to consider the durability and abrasive resistance of your rain pants fabric before purchasing, and to make sure that it will stand up to where you tend to hike most often.
For rougher environments, purchase rain pants with a higher denier, or if lightweight is of the utmost importance to you, choose a lower denier with less thickness.
DWR = Durable Water Repellent. This is the treatment or laminate that makes your rain pants waterproof. A good DWR will also enhance breathability so you don’t get too clammy on the inside.
DWR’s all lose their efficacy over time, however, you can retreat them to keep them functioning like new.
Elasticated waistband, drawcords or zippers, there are a variety of fastenings. Remember to choose one that will be comfortable with your backpack on and fully loaded.
This comes down to your personal preferences and where you tend to hike. You may prefer a relaxed, baggy fit, or a slim, more athletic fit. Tighter fits can be better for hiking through rougher terrain at speed.
You’ll want to be able to get your rain pants on quickly and easily at the first signs of rain. Large hiking boots, or people with large feet may struggle with rain pants that have smaller openings.
You don’t really want to have to remove your footwear if possible, to get them on. Some rain pants offer full length zippers, which I quite like, others 1/4 length and still others may have hook and loop features at the lower leg openings.
Consider how small you can pack your rain pants and save valuable space by choosing ones that are highly compressible. Some may come with a stuff sack, or pack into a pocket. Others can simply roll up and squash in to your backpack.
While not essential, you may like to have some other features to choose from, such as pockets, vents or pocket openings allowing you to access your regular pockets.
Some rain pants have cuffs that can fix to your boots like gaiters, keeping out snow or debris and water. If you have zippered rain pants, you should check for waterproofing and storm flaps to ensure that they do not leak.
When you’re choosing the best ultra-light rain pants for men, the most important aspect is to correctly match your priorities with the advantages of specific rain pants.
Are you likely to face extreme weather on a regular basis? Do you struggle with getting your footwear through regular sized openings? Do you need athletic performing rain pants? Or is light weight and packable your most important priority?
Choose your ultra-light rain pants accordingly, no one product is perfect for all uses and there are always trade-offs to be made. What looks like a bargain can cost you more if you have to buy twice, but you don’t want to pay over the odds for something you rarely use.
Choose an affordable, lightweight packable model that is appropriate for your circumstances, and that will provide you with the level of comfort and features you need, while keeping you dry out on the trail.
