I am looking at buying a set of lightweight, packable rain gear, and I found the Sitka Stormfront Light on sale for the same price as the Kuiu Chugach. The Sitka seems a little thin and flimsy, and I am worried that it won't hold up. I also don't like how it gathers at the ankle. I am a little worried about the Kuiu because my Attack pants are an athletic fit, and I want a little more room in a rain pant. What have you guys discovered?
