Product Details

The Men’s Ossa Overshirt is a button-up layer made for summer hiking when sun exposure is constant and you still want something breathable on. It works well over a tee or tank, giving you light coverage for long, exposed days on trail without feeling overbuilt for the conditions.

Arc'teryx uses a textured nylon ripstop here to help minimize that clammy, skin-sticking feel in hot weather, which matters once the day heats up and the pack goes on. The pop-up collar adds extra neck coverage when the sun is beating down, and when you don’t need it, the overshirt packs into its chest pocket for easy carry.

Why you'll love it

SUN COVERAGE

Built with UPF 50+ material to help protect you on high-exposure hikes. The pop-up collar adds extra coverage when the sun is hitting your neck all day.

BREATHES IN HEAT

Breathable fabric helps moisture vapour escape for better comfort in warm conditions. The textured nylon ripstop also helps minimize skin-sticking when the temperature climbs.

PACKS SMALL

When you don’t need the extra layer, it packs into its chest pocket for easy carry. That makes it practical for changing conditions on summer trail days.
