The original design was rancher Warner Glenn's. The fabric, a sturdy 7.5-oz. cotton twill, is one he insisted on to stand up to rugged use. Garment washed for softness, the men's outdoor shirt features rustproof brass snaps and pockets designed specifically to hold a compact camera. Orvis has pledged a donation to the nonprofit Malpai Borderlands Group for every shirt sold. Men's outdoor shirt is made of pure cotton. Washable. Imported.
