The Sitka Guard Sun LS Shirt solves three age-old issues for warm-weather expeditions: suffocating heat and humidity, exposure to harsh UV rays, and relentless insects. Built-in UPF 50+ protection and an Insect Shield® treatment defend against the searing sun and biting insects that are annoying at best, and downright dangerous at worst. It’s all built into an ultralight fabric that helps you stay cool through your hottest and most humid adventures.
