The Under Armour Boundless Pant was designed for use across multiple winter activities. Take them sledding, snowmobiling, or skiing and stay dry, mobile and comfortable. A StormProof membrane that's fully seam sealed keeps moisture away when you dip into the trees while the 4-way stretch fabric keeps you mobile as you hike to the top of the sledding hill. Built in boot gaiters seal out the snow while mesh-backed thigh vents dump excess heat when you're lapping your favorite runs. Reinforced cuffs and a scuff guard protect the pants from abrasion from your ski boots or ski edges so you can continue to wear the pants for many seasons through many activities.
