Whether you're on the trails or the slopes, the rivers or the mountains, you're going to want to add a pair of the Altitude Base Layer Thermal Tights to your kit. These tights are incredibly soft and will help keep you warm when it's cold and cool when it's warm for year-round comfort, no matter what the weather. So when you’re out in the elements being active, your legs will stay toasty warm without overheating and won't get stinky and sweaty like synthetics. The Altitude Tights are the same thickness as the Altitude tops. They are a classic thermal leggings style and great for warmer to cool temperatures as base layer pants. Tag-free labels, flatlock stitching and a flexible, ultra-soft ioMerino elasticated waistband help eliminate chafe and maximize comfort. The mid-rise style works perfectly with the Altitude Base Layer tops
