Excellent Condition! Mammut Summer Camp - Gray - Size L - Lightweight and Cool!! This Mammut Summer Camp hat is lightweight, cool, and breathable, with mesh on the back. I've used it 4-5 times since I bought it, and I've washed it each time. There's a little bit of wear, but it's still in good condition, so I'm listing it. Please refer to the photos for details. The product size is L. For reference, it fits me perfectly, and my head size is 58-60cm. How about it, Mammut fans? Thank you for visiting.
