I have a pair of Burton shells that would fit perfect (I wear the same size), I got a new pair of pants this season and have no use for them now. Just wear a pair of sweatpants or something underneath to keep you warm, they work fine. Id sell them for 40 shipped if your interested.
Can you PM me some pics? What kind of condition are they in and how long have you been using them?
I will PM you some pics tomorrow, but they are in 9/10 condition - no rips, tears or any kind of damage. I bought them from a friend who they did not fit, and I've only ridden them last season ~10 times.
