Alpinus Tactical Baselayer Mujer Sudadera térmica activa negro-azul GT43210 XL

Where most base layers stop at basic warmth, the Alpinus Tactical GT43210 pushes into true performance territory. Its thermoactive knit actively manages microclimate, pulling moisture away the moment you start moving, while the athletic cut keeps the fabric close without restricting. The black-blue colourway is both practical and sharp, suited to layered field use or solo wear in milder cold.

Highlights

• Thermoactive fabric with 4-way stretch for unrestricted movement
• Flatlock seams eliminate chafing during high-output activity
• Moisture-wicking and quick-drying to keep you dry from the inside out
• Odour-resistant treatment extends wear between washes
• Medium thermal insulation balances warmth and breathability
• Crew neck and long sleeves for reliable coverage under outer layers

In daily use

This top sits smoothly under a tactical vest, hiking pack, or winter shell. The slim, athletic fit means it won't bunch or ride up, and the flatlock seams stay comfortable even after hours of wear. The 92% polyester / 8% elastane blend gives just enough compression to feel supportive, while the brushed inner face adds a soft, warm touch. Whether you're on a cold-weather patrol, a winter trail run, or simply walking the dog in freezing temperatures, it regulates temperature far better than cotton or standard synthetics.
