The Altitude Waffle Long Sleeve is a base layer built from soft waffle-knit merino wool, offering natural temperature regulation and breathability across a range of conditions. Self-fabric cuffs and neckline deliver a clean, comfortable finish, while the long sleeve construction adds coverage when the temperature drops. A screen-printed graphic on the chest adds visual interest to an otherwise streamlined silhouette. Well-suited for layering on the trail, at altitude, or as a standalone piece in mild conditions.
