Lightweight waterproof overtrousers!

The Helium rain pants infuse the durability and lightweight waterproof protection of the Helium Collection that's been tested and trusted since 2010. Packing down to the size of your palm, these make a great emergency layer or dependable option for fast-and-light adventures.

Durable, windproof, and shockingly breathable, these waterproof overtrousers are made for outdoor adventure. Leveraging Diamond Fuse technology—a fabric engineered to be lightweight yet durable through extended wear and washing—these expert-designed women’s rain pants have all the details you need to stay dry, including taped seams, a drawcord waist, and lower leg zips so you can pull them off without taking off your boots (you’re welcome). And, did we mention these pants pack down to the size of your palm?

Keep these handy on your next hike or bike tour, or fold them into their stuff-sack back pocket and throw them in your backpack. When a downpour rolls in, slide them on, then carry on feeling so comfortable, you’ll almost forget it’s raining.

Why we love the Helium Rain Pants

Super-lightweight waterproofs are hard to find especially at larger sizes. These waterproof over-trousers fill that gap, and although not available in the specific 'plus sizes' from Outdoor Research, the extended sizes will cater for up to a UK size 18. 

If you need a pair of reliable but super-packable and lightweight waterproof over-trousers for fast-packing hiking, thru-hiking, bike-packing, or other adventures where space and weight are at a premium, the Helium rain pants are for you.

Is your size not available?

As we introduce the plus size range to the UK we have very limited stock in limited colours and sizes. If your size or colour is not available please complete the form at the bottom of this page or contact us stating what you would like to purchase. We can let you know when it will be available, or order it in for you.
