Limited pack space but need a lightweight layer you can count on? Bring the Men's BUGS AWAY® Sandfly™ Jacket, especially if you're trekking through remote forests or exploring a new country. Its quick-drying and abrasion-resistant nylon fabric features bug-blocking Insect Shield® treatment, which gives you the invisible, odorless protection of Permethrin and lasts up to 70 washes. This jacket, which easily stuffs into its own left pocket, features mesh panels for breathability. An adjustable hood provides protection from the sun, rain, and whatever else Mother Nature throws your way. Customize your fit with the elastic cuffs and hem, and stow your essentials in the zippered security pocket on the left chest.
