These are the best pair of pants I have owned. Keeps me warm, dry, blocks wind, and extremely breathable. Wore these with a base layer in 25-30" temps and very very comfortable. Very relaxed fit and durable. I own a pair of burtons also and it just doesn't compare. I was also considering a pair of arcteryx but decided to try these and couldn't be happier. I am about 5'9 and weigh 135. Usually wear a 29-30, I purchased an XS with relaxed baggy fit with perfect length.
