The North Face Summit Series Men's L1 Pant is a base layer for harsh, alpine environments. Freezing cold, whipping winds, snow, ice and more. You're not only looking to climb to the top in these conditions, you're looking to survive them. It all starts with a base layer and this is the 1st in 5 available layers. The Thermolite® technology is a polyester/elastane blend that will keep you warm while also wicking moisture. All thanks to hollow-core fibers that trap body heat while also evaporate moisture quickly, so you stay comfortable from your first step up the mountain to your last step down.
