The Marmot Uptrail Muscle Tank is built for high-output activity in warm conditions where maximum ventilation and minimal weight are essential. The open mesh ventilation zones on the back and underarms allow continuous airflow, helping to dump heat quickly during intense effort. The soft stretch blend ensures comfort and freedom of movement without clinginess, making it ideal for trail running, hiking, and summer training sessions.
Made from a recycled polyester and lyocell blend, the fabric offers a natural next-to-skin feel while maintaining durability and quick-drying performance. The slim fit and lightweight construction make it an efficient base layer or standalone piece in hot climates.
