I come from the old school snowboard world and don't understand why people pay so much money for crappy gear with someone's else's logo on it in large florescent letters. Maybe you like being a walking billboard. I'm not getting paid to advertise for no one. I just promo gear and companies that treat me right.
Go ahead and stone me, but I ride Burton Snowboards AK gear. Most is Gortex/20k Waterproof, you have to look for the AK line though. Warranted FOR LIFE. Already got a new pair of pants last year out of that deal when I separated the seam at the bottom of my pants. You can buy lots of last years Burton AK gear at 30-70% off on the internet if you know where to look.
Snowboard gear is generally reinforced in the same areas that are important to sledding, knees and butt. The snowboard market is saturated so you can get gear a lot cheaper than "snowmobile" specific gear. That and warranties are pretty important to me, I'm hard on the equipment and generally shred a lot of gear in my first year using it.
For example, I busted the side retention clips on my Kilm drakkar motox pants on the first ride. Probably cause I'm fat. Reminds me, I need to warranty those suckers up. Right after this cheeseburger.
