Blazing afternoons on the river, glassy lakes at noon and long walks along open banks need more than a basic long sleeve. The M's Mirage Sun Long Sleeve Tee is built as a lightweight layer for intense sun, with a clean profile that works on its own in mid-summer or under a light shirt when the breeze picks up.

It's innovative cooling performance, 4-way stretch and quick-drying fabric made of 86% recycled polyester / 14% elastane, 150 g/m² moves with every cast and paddle stroke. Coolcore® chemical-free cooling technology helps regulate your temperature by pulling moisture away from the skin, so you stay cool, dry and comfortable in hot, humid conditions. Certified UPF 50+, with materials that meet GRS and Oeko-Tex® Standard 100, this sun tee offers strong UV protection in a more responsible package.

Flatlock seams reduce chafing under pack straps or waders, and cuffs with thumbholes extend coverage over the backs of your hands without getting in the way of your grip. A simple printed logo signs off the design without adding weight or bulk. Built for long, bright days on the water, this piece quickly becomes the first layer you reach for when the forecast calls for clear skies.
