“Mtn Hdwr - WindSHIRT not Wind Jacket”

“I normally wear a size Large. This windshirt is cut very trim. If you expect to wear anything under it (fleece, capilene liner, etc) plan on ordering the next size up. I originally ordered a Large and returned it for an XL. The XL is perfect. Realize that this is a windshirt. Not a rainshell. It has one pocket for use as a small stash pocket or a zip-into storage pocket for the shell itself. Excellent for the service intended - but certainly not a bomb-proof shell.”
