【Fleece Lining】 This long-sleeve running shirt features a soft fleece lining fabric with quick-drying properties that rapidly wicks away sweat during high-intensity activities, helping you stay warm in cold weather.

【Lightweight Stretch Fabric】 Crafted from 95% polyester and 5% spandex, it delivers exceptional four-way stretch and flexibility. The slim-fit cut hugs your form without feeling restrictive, while flatlock seams minimize friction for all-day comfort.

【Crew Neck】 The meticulously stitched crew neck lies flat against the skin, preventing neckline friction and constriction during movement. This ensures focused comfort while pairing seamlessly with other winter outerwear.

【Versatile Use】 Ideal for diverse cold-weather activities like running, hiking, skiing, and travel, this women's thermal long-sleeve shirt becomes your essential base layer this winter.

【Machine Washable】 Care for this women's base layer is straightforward. For machine washing, we recommend cold water and a gentle cycle. After washing, lay flat to dry or hang on a clothesline, avoiding direct sunlight.
