Sudadera Térmica Hombre Alpinus Active Base Layer Gris GT43860 Talla S

Engineered with advanced moisture-wicking fibers, this men's thermoactive sweatshirt pulls sweat away from your skin to keep you dry during high-output activities in cold conditions. The Alpinus Active Base Layer in gray is a technical first layer built for winter sports and outdoor training, combining breathable insulation with a slim, athletic cut that moves with you.

Overview

Part of the Active Base Layer collection, this long-sleeve top is designed for men who demand performance from their base layer. The synthetic blend fabric offers four-way stretch and quick-drying properties, while flat seams and an anti-chafing design ensure comfort under a pack or mid-layer. A round neck and athletic fit make it ideal for layering under a shell or wearing alone during shoulder-season workouts.
