Cold-weather cyclists, this NUCKILY fleece set is made to keep you warm and comfortable on winter rides. The long-sleeve jersey is made from thermal fleece-lined polyester-spandex, which blocks wind and retains body heat. It has a full-length zipper, a stand-up collar, and a longer back to keep cold air out. The matching pants have a 3D padded seat to relieve pressure and reduce soreness during long rides. Both pieces are breathable, stretchy, and have reflective details for low-light safety. The jersey has three back pockets plus a zippered pocket for storing your phone, keys, or snacks. The pants have zippers at the ankles for easy on/off. It's a slim but comfortable fit - if you like it looser, consider sizing up. Whether you're road cycling, commuting, or just enjoying a winter ride, this set provides warmth without bulk. Hand wash recommended to keep it in good shape. A great value set from a brand that specializes in cycling gear.
