I have both the one's that go over your jacket and the one's under the jacket.I have had them both for 2 seasons no problems with them falling apart yet.The only problem I have had is when it gets real cold they get stiff I guess it is from the gortex
I have pair of these in the over-style and a pair in the under-style. The gore-tex insert keeps you dry, and they'll last a couple seasons, all for a reasonable price. I've found mid-high end Burton stuff to be as good or better than stuff from other companies, and I'm not even a fan of Burton.
Save your money/time dealing with warranty and skip the Burton outerwear.
I wear the AK line Goretex jacket and pants and they've been warm and bullet proof in all kinds of nasty weather. Plus they have plenty of room to bounce around in without making me look like I just broke out of prison.
