On a cold morning ridge hike or a fast-paced tactical training session, the Alpinus Tactical Base Layer sweatshirt keeps you warm, dry, and moving without restriction.

Why choose it

The Tactical Base Layer excels in cool conditions where you need warmth without overheating. Its thermoactive fabric traps body heat while actively moving sweat away from the skin, and the 4-way stretch allows a full range of motion for climbing, skiing, or carrying gear. Flat seams prevent irritation under a pack or plate carrier, and the anti-odor finish keeps you fresh on multi-day trips.

Ideal use cases

• Base layer for tactical operations or outdoor work in cold weather
• Hiking and trekking in spring, autumn, or mild winter
• Winter sports such as skiing or snowboarding under a shell
• Everyday cold-weather training and commuting
