I wear a size 33 in jeans. Bought the large size b/c my mediums (Burton Cargo's) were getting a bit snug from gaining a few LBs. they were plenty big enough. pulled the velcro straps on the side to tighten them up a bit. I also wore a pair of impact shorts and knee pads under them and had plenty of room with more to spare. but not too baggy at all. Would definitely buy another color if they had more in my size. also, great waterproofing and great insulation. almost got too hot with the first layers too.
