We throw on the Smartwool Merino Sport Ultralite Hoodie for everything from working on boulder problems to slacklining in the backyard on a down day. This hoodie hybrid blends merino wool with Tencel to offer the perfect balance between softness and temp-regulating performance. Plus, we appreciate that the merino naturally fends off funky odors that result from an active lifestyle, so we can feel confident heading to the brewpub right from the trail.
