Millet Summit Board TS SS men. We've reached the top. Our Summit Board technical t-shirt offers excellent thermal comfort. Lightweight, stretchy, and breathable, its Polartec® Power Dry® fabric keeps us dry even when we're pushing ourselves. Its double-sided polyester construction (84% recycled) is soft against our skin and wicks moisture away quickly. With its classic cut, round collar and short sleeves, it's perfect for all our mountaineering trips. Its graphic is a reminder of the most beautiful peaks and a source of inspiration for us every time we head out.
