The ultra-light running belt is designed for race-focused runners who need a reliable and comfortable storage solution without compromise. Thanks to its innovative design, it keeps your kit stable on long routes while minimising bounce and distracting movement as you run.
Soft, airy mesh (airmesh) in the contact area provides breathable comfort directly against the body, so the belt can be worn for hours without skin irritation. Two adjustable elastic closure cords allow precise fine-tuning of the fit for any body shape, and the belt is offered in two unisex sizes.
- Organisation without bounce
The belt features a zipped pocket for a phone and keys, four front drop-in pockets and a spacious pass-through rear pocket, so everything stays firmly in place even at high pace; the rear storage pocket also fits a 500 ml Hydraulics soft flask (sold separately), stabilised with the removable WingStay system. - Versatile system for poles and layers
The removable bungee cord system lets you carry trekking poles in three different positions – front, diagonal rear or vertical rear – and can also be used to secure a light clothing layer, making the belt a truly versatile helper for changing terrain conditions.
