Tree Wool FL Long-Sleeve Shirt - Men's

What Our Gearhead® Experts Are Saying:

"I wear this on everything from hikes to travel days. The wool–lyocell blend breathes well, dries fast, and feels good even when you’re moving hard or wearing it for hours."

We reach for the Tree Wool FL Long-Sleeve Shirt when the day calls for a do-everything layer that feels great from the trail to town. Its merino wool and lyocell blend manages heat and moisture naturally, keeping us comfortable on warm climbs and breezy ridge walks. The fabric dries quickly after sustained effort, and the relaxed fit gives us the freedom to move smoothly on scrambles and long approaches.

Underarm gussets help maintain mobility on climbs or during technical hiking, while the soft, all-natural fibers resist odor during multi-day trips or busy travel schedules. Whether we’re gearing up for a shoulder-season tour, settling in around camp, or meeting friends after a day outside, the Tree Wool FL Long-Sleeve Shirt stays comfortable, breathable, and ready for whatever comes next.
