Durable nylon Supplex fabric resists abrasion when you're scrambling around in the Women's Cassidy Shirt from Marmot. This short-sleeve button-up is not only durable, but it's quick-drying and moisture-wicking as well, so you feel fresh at the end of a long day of hiking. A shirt-tail hem, flat-felled seams, and double chest pockets give this shirt a classic look.
