Circle Running Hat Size M Made of nylon fabric, it's water-repellent. Features a large ventilation panel at the back. Worn once in the city. The absence of a front logo makes for a very simple design. Perfect for running, as well as hiking and camping. Selling to organize my gear. The BCHat originally started as the limited edition gry label and has now evolved into the more race-focused Elite collection. It maintains protective capabilities that can be used in any weather, using 100% recycled three-layer fabric. The back panel has also been redesigned to always ensure breathability, and the COOLmatic|EXP material back vent is adopted. With a complete welded construction, it's surprisingly packable and the perfect partner when a storm hits. ● Lightweight and breathable three-layer construction with temperature-regulating recycled COOLmatic EXP material. ● UPF +40 UV protection. ● Machine washable. ● Flexible, 360-degree foldable, smooth-curved brim. ● Reflective label for increased visibility at night.
