Tree Wool FL Long-Sleeve Shirt keeps us moving in comfort with fast-drying wool performance
What Our Gearhead® Experts Are Saying:
"I throw the Tree Wool FL Long-Sleeve in my pack every time I’m headed out for a shoulder-season hike. It feels super soft thanks to the Tencel, dries way quicker than pure merino, and keeps its shape even after repeated use. The gusseted underarms are a quiet MVP—great mobility without any ride-up."
We count on the Tree Wool FL Long-Sleeve Shirt when the trail calls for breathable comfort and multi-day durability. Built with a thoughtful blend of RWS-certified merino wool and smooth Tencel lyocell, this layer offers fast moisture management, natural odor resistance, and soft next-to-skin comfort—ideal for early starts, summit pushes, or winding down around the fire.
A functional underarm gusset enhances mobility, while the fabric’s enhanced shape retention means it holds up season after season. Whether worn solo on crisp hikes or layered under a fleece during shoulder-season travel, the Tree Wool FL Long-Sleeve is one of those pieces that goes the distance without missing a beat.
