Finally found the right fit on third try. I'm only 5'9", but due to years in the gym, I have a 27" thigh when measured over jeans. ( These MUST be ordered strictly by thigh measurement...the length can be cut down very easily, and the waist is adjustable.) The chaps themselves are very comfortable without the thermal inserts (still need a little stretching/breaking in before the thermal inserts will fit over jeans, but getting there) and since I'm a daily rider, I have been using them sometimes every day. Without the liners, they cut the wind well, make cold evening rides far more enjoyable, and once broken in, just mold to you until you forget they are even on. The inserts will be even warmer, so cold weather is now covered! Good product, once the sizing is figured out, and as long as they are cut a bit long in length, they work great even if your kicked up on Highway Pegs.
