I live in Denver and use this jacket from September to April. Its a great shell that withstands wind and rain. Its great for biking to school and with a sweatshirt underneath, I'm both warm and dry, even in the winter. I own a lot of TNF products, but the venture is probably the most versatile one I have. Also have Marmot and MH jackets, but the Venture definitely keeps me dryer than the MH Epic. I'm 5 ft 5 and 115 lbs, the small is perfect, because I always have a relatively thick layer on underneath.
