What a great pair of pants for the outdoors. Cut to fit comfortably and made to move.From the lined waist band to the drawstrings on the leg hems all the attention to detail Arc'teryx put into these pants make them a must have tool for being in the outdoors in the winter. While snowshoeing I put these pants to the test, they are very breathable but kept the crisp December air out. Even stepping over the biggest of fallen trees trunks I never felt as if I was stretching them near their limit. Arc'teryx makes great pants and gear.
