Meet the Dera B01. The Dial-Fit Running Belt Made To Move With You. No bounce, no fuss. Dera makes running gear inspired by the simple act of running outside. The gear you carry should disappear, noticed only when you need something inside it.

• The dial-fit system tightens evenly around your body, so you can fine-tune the fit mid-run and reduce bounce without missing a step.
• Includes a co-developed 575ml HydraPak UltraFlask with a locking cap, designed specifically to work for trail efforts.
• The belt can fit up to two of the 575ml flasks, allowing you to carry over a liter of fluid with space for gels, your phone, and an extra layer.
• B01's primary fabric is among the most durable in any belt, resisting abrasion and punctures while retaining next-to-skin comfort.
• Front and rear storage keep your flask, phone, nutrition, and gear thoughtfully separated while providing multiple access points to each storage zone.
• A water-resistant stash pocket protects salt tabs, a car key, or emergency cash.
• An external zip pocket gives you quick access to the small stuff you don’t want to lose.
• Rear pass-through sleeve securely holds poles or layers.
• Weighs just 4.2oz in a size medium, disappearing on your run.

Size Guide: Take your measurement at the midpoint of where you'd like the belt to sit on your body. Note: this is not your pant size. Measure while wearing whatever you plan to wear with the belt. If you prefer to wear a belt on top of a shirt, measure over your shirt. If you sit between sizes, size up if you prefer a more relaxed fit, size down for a performance fit.
