Base layer t-shirts should not be overlooked. Based on the original Helly Hansen base layer, this short-sleeve t-shirt for men keeps you dry during aerobic activities and is ideal for climbing, skiing, sailing and sports training. As an extra layer in cold conditions or as a stand alone UV protection and moisture management garment, no other base layer top comes close in versatility. The HH®Dry construction with 100% Lifa is a quick-dry, extremely breathable and super-lightweight high-performance base layer. Continually perfected over the last 40 years, Lifa® Stay dry technology is the unique ingredient of all Helly Hansen base layers.
