perfect rain pants

it would be perfect if it ran a bit larger would appreciate more room as I'm a taller guy 6'3 and with a linebacker build it fits snuggly in a few on my quads and thighs but overall great pants

A Classic that Keeps Working

I ordered the pants and jacket to replace some old faithful ones that have been reliable for years. I've always been happy with the Helium line for backpacking. Although I wouldn't call them super durable thats not really what they are meant for. I use them as the lightweight layer to keep rain off on the occasional rain during backpacking trips or light rain.

lightweight rain pants

A great lightweight pair of rain pants. Used them as a shell during a snow storm and stayed dry.

Great lightweight rain pant. Highly recommend for occasional use on trail. Not the rain pant you want for an absolute downpour or beating the brush but unbeatable if you’re looking for something to handle the occasional rainstorm while recreating.

Good rain pants, heavier than advertised

Good rain pants but heavier than advertised (by about 1/3). I tried on and weighted the medium and the large, but were about 200 gr. Cut was nice, functional, no extra design stuff that I did not need. The large would have fit but I returned because of the weight.

Great lightweight rain paints!

Great lightweight rain paints - do what they are intended to do. And a great warranty, as my seams split after 4 years of good usage, and OR completely warrantied them

Light weight as advertised

No field experience yet and I kind of hope it takes sometime before it gets any. Very packable and light weight so the jacket and pants make a good standby. There aren't any pit zips or hand pockets so I have some concern about its ability to vent.

Top Rated for Ultra Light Hikers

Same material as the Helium Rain Jacket. Sizing is perfect. Keeps me dry for short periods of time. Don't expect these to keep you dry all day! They work for an hour or so then wet through, but that's expected. These are excellent for through hiking when weight means everything!

Good foul-weather pants

Seem to fit true to size. I'm 5'10" 160lbs and wear 30/32 pants. These fit over most of my pants without a problem and I haven't had any issues with movement restriction. These have been a great addition to my foul weather gear for my boat.
