Ideal for sunny hikes, this button-collar shirt offers UPF 50+ protection and layers effortlessly over a t-shirt or tank top.
Its textured ripstop nylon construction prevents it from clinging to the skin in hot weather, while the collar can be raised to protect your neck when the sun is at its highest.
