The adidas adi365 Running CLIMAWARM+ Leggings are insulated, moisture-wicking tights designed for cold-weather running, featuring stretchy fabric for movement, reflective details for low light, and practical pockets (side and back zip) for essentials, keeping you warm, dry, and focused on your run. They use CLIMAWARM+ technology to trap heat without bulk and provide a snug, supportive fit, though some users found sizing tight. Never worn, took the tags off, washed them and then realized they were a XS not a S !
