I purchased this jacket for a trip to Mt. Rainier that I am taking next month. My review is based on comfort of fit, functionality and quality. The jacket fits great. I am 242lbs and 6'2" and I purchased the Xlarge. When I am wearing the jacket there is enough comfortable space for a base layer and a mid layer. The cuffs are adjustable to seal the wind out and the waist line of the jacket has extra length and draw strings. I stood in the rain for an extended amount of time and this jacket repels water well but is not water proof. The fabric is amazingly comfortable and the jacket is very low weight. As for warmth levels I can't rate that until I take it on the mountain as I live in Texas and it is hot year round here. So far I feel that this jacket was a wise purchase.
