Why We Like The Helium Rain Jacket

The Helium Rain Jacket delivers the most durable, lightweight storm protection that Outdoor Research has to offer. Its Pertex Shield Diamond Fuse shell offers reliable waterproofing, comfortable breathability, and fully sealed seams the prevent a single raindrop from seeping through.

great packable rain jacket

This is my go to "toss in the backpack just in case" jacket for hiking/travel and my everyday go to in the summer and shoulder season rain jacket. Packs down small into it's own pocket, is light weight and I haven't had it soak through yet here in the Pacific Northwest. Pretty breathable, good for summer rains and shoulder season if temps are moderate. fit is athletic with just enough room for a slim base layer if you need it.

Great product, just what I was looking for. Something to throw in my pack for light rain. If I expect heavy rain I take my Foray II Gore-tex Jacket another great product from OR

Perfect rain coat!

Absolutely great jacket! I picked the wrong color so want to return it. I will definitely be just changing the color as I will get a ton of use from it!

The perfect lightweight breathable jacket!

In the PNW, I run with my Helium Rain Jacket. In the cooler wet season it helps keep me dry and warm. In the warmer part of the year, its lightness and breathability does not cause me to get over heated. It is the perfect jacket for all my outdoor activities. PS: I've owned this jacket for 4 years. It is quite durable for such a light jacket. I'd recommend it to anyone looking for a terrific light weight running or biking jacket.

Super Lightweight!

If you want to lighten your load, this jacket is for you. Super lightweight., no-frills jacket, and yet it has enough features to be functional. It keeps me dry and warm in a windy downpour and takes very little space in my pack. The hood is large enough for a climbing helmet or can sinch up when not wearing one.

Thin, but a good addition for a light pack

Too short for a tall person

I'm 6'4" and this jacket (size XL) was just too short, did not get a chance to test it out because of this and returned it. Even on someone not as tall I'd think the length may be lacking

So good I bought it again

I had this rain shell and used it constantly. It keeps me dry in an urban downpour or a backcountry bike ride. Very light and packable, and the new version has a more durable hood.

Nice packable water resistant jacket.

Bought this for cycling in the light rain. Nice fit and weight. I'm 6' 3" and 200 lbs. and a large is a nice slim fit. Packs down small and is easy to stow. Not 100% waterproof, but kept me mostly dry on a 3 hour downpour bike ride. If you're on the husky side, you might size up to an XL.
