Fabric: Stretch Nylon Twill
Price Paid: $50
I have tried many other climbing pants and this one beats them all. When they say stretch they mean it. The fabric with the design just makes this pant awesome if you want a great range of motion. And their roll up leg always stays rolled up, and is easier than other brands. It's really worth checking them out.
I was hesitant to try them because they're a new company but they offer a full guarantee, which is sweet, and they were cool to deal with.
