The Alvra Summer Shirt by Mammut is a short-sleeved blouse for men, designed to keep you comfortable during warm-weather adventures or relaxed days outdoors. Its understated style fits in just as well on a trail as it does around the campsite or in town.
Crafted from 55% hemp and 45% lyocell, this shirt balances natural strength with a soft hand feel. The hemp fibers lend durability and breathability, helping air circulate and reducing wear over time, while the lyocell component wicks moisture away from the skin and speeds up drying when you work up a sweat. A regular fit gives you freedom to move—whether you’re scrambling over rocks or settling into a well-earned rest.
Hemp is a plant-based fiber known for its toughness, breathability and natural resistance to odors. Lyocell is a regenerated cellulose fiber made from wood pulp in a closed-loop process, prized for its ability to absorb moisture and retain softness. Together, they create a quick-drying, durable fabric that stays comfortable across long days outside.
