Men's Thermoactive Sweatshirt 4F M103 Navy Blue L/XL

Cold-weather training often forces a choice between warmth and mobility—bulky layers restrict movement, while lightweight tops leave you chilled. The Men's Thermoactive Sweatshirt 4F M103 solves this by combining thermal insulation with a stretchy, athletic fit that moves with you. Its navy blue design and moisture-wicking fabric keep you dry and comfortable during high-output activities in low temperatures.

Who is it for

This sweatshirt is built for men who train outdoors in autumn and winter—runners, cyclists, and winter sports enthusiasts who need a reliable base or mid layer. The L/XL size suits broader frames, and the round neck and long sleeves provide full coverage without restricting movement.
