This seems to have been the go to light weight rain jacket for a long time now. I've had mine around 10 years now. It must have been huge when I first got it. It's been a great emergency rain jacket on all my mild season trips.
I see some pretty bad reviews for this jacket. Maybe there was a quality change but I doubt it baring a few people who got a defective product (backcountry has a 100% satisfaction guarantee for a reason). I have a hunch people are not grasping what this jacket is designed to be. It is a light weight rain jacket. Key term there being "light weight."There is a reason why there are Gore-Tex pro shell jackets that sell for $600 dollars. This jacket is designed to keep you dry until you get to shelter. You are at a soccer game, it rains, you put the jacket on, the game ends, and you go to your car. You are hiking, it starts to sleet, you find a site, and you pitch a tent. The description is exactly right. It is a "just-in-case shell." Of course you are going to wear out the laminate if you wear it with a pack. Of course it's not going to breath fantastically so it is going to get clammy. This is often time what is happening when people think the jacket it leaking.
If you boys want a jacket that will perform like an Alpha SV then you're just going to have to pony up the 600 bucks for an Alpha SV and stop expecting a $100 light weight rain jacket to perform miracles.
