About Reflex Belt
At the front, a secure pocket keeps your smaller items, like keys, cards, or energy gels, safe and within easy reach. Two extra-large pockets provide enough room for a lightweight jacket or a pair of 600ml soft flasks, making it easy to stay fuelled and weather-ready. The Reflex Belt also includes a tubular pocket with silicone bands to securely carry your poles, so you’re always ready for technical sections or long climbs.
Adding to its practicality, the integrated race bib holder saves time and hassle on race day, while reflective loops increase visibility and make pocket access easier in low light. The belt is constructed from breathable, stretchable mesh, designed to sit comfortably without restricting movement or airflow, helping wick sweat away and reduce irritation as you run.
For the best fit, measure 2 cm below your belly button. These belts are known to run slightly small, so we recommend choosing a size up for optimal comfort and performance. The Reflex Belt is a no-fuss, high-function accessory for trail runners who like to move fast, light, and with confidence.
How does it work
The Reflex Belt uses a carefully engineered layout of six pockets to distribute gear evenly across your waist. The combination of secure closures and stretch mesh keeps items stable, even during dynamic movements. Silicone bands inside the tubular pocket grip your poles firmly, while reflective loops and the ergonomic shape make it easy to access gear without slowing down.
Its construction from stretchable, breathable mesh helps reduce sweat build-up and improves comfort across longer distances. Whether it’s used as your main storage solution or to complement a hydration vest, the Reflex Belt is designed to adapt to your running needs.
