Thank you for viewing. Comfortable outdoor cap made with breathable material. - Brand: MAMMUT - Color: Black - Style: Cap - Design: With a brim - Features: Breathable material - Uses: Outdoor activities, mountaineering Purchased about 5 years ago at the Koya Sanso Ginza store. Used about 5 times. It's a size L, but it fits me perfectly with a head circumference of 59cm. There is some wear and tear, but I feel it's not noticeable, in my subjective opinion.
