This is a flight cap from NUT-BUTTER. I think it's something that's hard to find. I've used it a few times for snowboarding. The inside is fleece and warm. ＜NUT-BUTTER＞ is a private label run by Yoshimura "Naru" Narufumi (@narubrain), a pioneer and legendary professional snowboarder in the Japanese snowboarding scene, who continues to produce a very small quantity of items in a workshop that feels like a secret base. The items from ＜NUT-BUTTER＞, curated by Naru, who has connections with key figures in various fields, have many core fans beyond the snowboarding scene. In recent years, with Naru as one of the core members, he has been the organizer of the collective "BORDERLESS MAGAZINE (@borderless_magazine)", which brings together snowboarders from various fields.
