Product Insights
The On Thin Running Belt is a 50-gram, adjustable belt that stays flush and bounce-free under race apparel, offering easy mid-run access to essentials through a zippered and two slip pockets that don't require rotating the belt. Its slider buckle allows on/off without stepping out, and the stepless adjustment fits 26 to 42 inches. The front material combines recycled polyamide, UHMWPE, and spandex for abrasion resistance and comfort, while a twist-to-lock key clip prevents loss. The tradeoff is that even though it's machine-washable on cold, high heat should be avoided.
