Anyone whos stemmed their way up El Matador knows the value of stretch. These Baggies get their forgiving flex from a lightweight, stretch-woven nylon/spandex fabric thats durable, quick-drying and has 40-UPF sun protection. For serious body dynamics (think yoga), they have a skin-friendly elasticized waistband and internal drawstring. The vertical side pockets feature drain-and-dry mesh, and the rear patch pocket closes securely with a snap button. Inseam is 9".
