The best mountain biken' shorts I have worn. Solid, hands down, no questions. The outer shell is a good, light weight material with slight stretch to the material. Inner shell fits perfectly. The legs openings are tight enough to stay put, but not cut off blood supply. Chamois is well padded but not overly bulky. These shorts are CLEAN looking. Pockets are flat, but who needs pockets when using a camelbak. Smartwool has done it again.
