I dare say these are the best pants possible for a split boarder, or anyone who plays around in the backcountry for that matter. I had heard great things about fly low, and wasn't disappointed. These are a little too baggy for my taste, but I don't tele and didn't want the reinforced knees. Doesn't hinder performance though, there's lots of room to move around. Just a style preference. The dual vents on both sides of the legs are super clutch for cooling things down when you're cranking up mountains, I don't know how I ever lived without them. I was surprised that I can operate all the zippers, including the vents, with one hand. These pants aren't insulated, which is what I prefer but might be a problem for other people. I accidentally just wore my boxers underneath one day and was plenty warm. They've also stayed completely dry in spring slush and rain.These are super bomber and held up really well to riding tight trees in the back country, not to mention regular slices from edges. If you spend most of your time in the backcountry and don't mind the baggier fit, GET THESE PANTS !!!
