These are warm, comfortable and light. I am a 6 foot 13 stone bloke with reasonable arms, and the s/m size is perfect. The arm grippers are at just the correct tension, they stay firmly in place without cutting off your circulation.In fact you don't know they are on. If you get too warm, they scrunch up to hardly anything and easily fit in pockets or saddlebags. The only trouble I had with them is getting the logo straight.Totally good product.
