What Our Gearhead® Experts Are Saying: “This is one of those pieces I wear way beyond riding days. The merino blend breathes incredibly well, doesn’t hold odor, and feels soft enough for all-day wear. It layers cleanly under shells but works just as well on hikes or casual days.” We reach for the Phayse T-Shirt when we want technical performance without committing to a full base layer. Burton designed this piece to live comfortably next to skin, delivering the natural temperature regulation of merino with a soft, easygoing feel that works on snow, on the trail, or around town. The merino-wrapped nylon core yarn keeps pure merino against the skin for breathability and odor control, while added durability ensures it holds up to repeat wear. Strategic mesh venting boosts airflow where heat builds fastest, and four-way stretch keeps movement unrestricted. Lightweight, versatile, and quietly technical, the Phayse T-Shirt is built to earn its place in daily rotation.
