Insulated ski suspender pants designed for ski runs and winter mountain trails. The cut conforms to the female body. Fully seam-sealed for waterproof and windproof protection, while the inner layer of high-efficiency insulation material continuously retains heat in extreme cold while maintaining good breathability and preventing sweating. Detachable straps and a hook-and-loop elastic waistband offer dual adjustment for a secure fit to different body types. Side zippered leg openings facilitate the on/off of ski boots, and built-in anti-slip strips on the ski skirt lock in warmth and prevent wet snow from entering.
