The Marmot Men's Uptrail Active Tank Top is a sleeveless training top built for high-mileage efforts on and off the mountain. Its mesh back and underarm panels dump heat fast and keep air flowing, while the drop-tail hem adds coverage as you move.
The lightweight jacquard fabric blends recycled polyester, lyocell and elastane for soft, never-clingy stretch that dries quickly. It is cut in a slim fit with a 28.5in center back length and weighs just 4 oz, and it is machine washable for low-maintenance care.
