Have limited pack space but need a lightweight layer you can count on? Bring the abrasion-resistant ExOfficio Men's BugsAway Sandfly Jacket, especially if you're trekking through remote forests or exploring the countryside. This jacket for men, which easily stuffs into its own left pocket, features mesh panels that enhance breathability when your adventure heats up. An adjustable hood provides protection from the sun, rain, and whatever else Mother Nature throws your way. Customize your fit with the elasticized cuffs and hem, and stow small essentials like your phone, keys, and cash in the zippered security pocket. Whether in the backwoods or the backyard, Insect Shield technology helps keep you protected with built-in invisible, odorless insect protection that repels mosquitoes, ticks, ants, flies, chiggers and midges (no-see-ums). The active ingredient in Insect Shield products is so tightly bonded to the fabric fibers that it retains effective repellency through 70 washes.
