The Alvra Summer Longsleeve Shirt from Mammut is designed for warm-weather adventures and everyday outdoor use. Its lightweight construction offers sun protection and coverage while keeping you comfortable on the trail or at camp.
Made from a blend of 55% hemp and 45% lyocell, this long-sleeve shirt dries quickly and allows air to circulate, helping you stay cool as temperatures rise. The regular fit gives you room to move without excess fabric, making it suitable for layering under a vest or wearing on its own during summer hikes.
Hemp is a natural fiber known for its strength, breathability and resistance to odors, while lyocell is a type of rayon made from wood pulp that absorbs moisture and releases it quickly. Together, they create a fabric that balances durability with softness, so you can stay comfortable and dry even when you work up a sweat.
