What Our Gearhead(R) Experts Are Saying:"I like these as a lightweight base layer for high-output days in the cold. They manage sweat really well, and the fit is snug without feeling restrictive. The waistband is comfortable under layers, and they stay dry even when I'm working hard on the skin track or hike."We pull on the Summit Pro 120 Tight when the day calls for movement in cold conditions and staying dry is just as important as staying warm. The North Face designed these tights for high-output pursuits, giving us a base layer that works with us whether we're climbing, hiking, or layering up for long winter days. Built with DOTKNIT(TM) fabric, these tights actively move moisture away from the skin through engineered knit zones, helping regulate temperature when our effort ramps up. The lightweight recycled polyester construction feels soft and breathable, while anti-odor technology keeps things fresh through extended wear. Low-profile merrow stitching reduces bulk and enhances next-to-skin comfort, and the wide elastic waistband stays secure without digging in. Designed for performance layering, these tights keep us comfortable from first step to final descent.
