Practicing a sport all day long requires reliable equipment to get the most out of it. The Helly Hansen Lifa men's baselayer pants help you keep the warmth close to your body while wicking away sweat. With their flat seams and elastic waistband, you'll almost forget you're wearing them! This garment is part of a layering system that provides comfort and warmth for your outdoor activities. Easy to layer, this base layer enables you to regulate your body temperature by wicking moisture away. This onion layering system is made of three types of clothing. The first layer, worn next-to-skin will provide warmth and quickly move moisture away from your skin. Then, the second layer, is the insulation or fleece, that provides warmth while also dissipating heat during periods of high output. And finally, the third layer, the shell, which is the most weather-protective layer, worn on the outside of all other layers.
