Product Description
One of the standout features of the PX 3.1L is its secure front pocket, perfect for storing smaller items such as keys, credit cards, or energy gels. Additionally, the belt includes two extra-large pockets, which are ideal for stashing a lightweight jacket or a pair of 600ml soft flasks. This thoughtful design means you can stay hydrated and prepared for any weather conditions without feeling weighed down.

The PX 3.1L also boasts a tubular pocket equipped with silicone bands, providing a secure spot for your poles. Whether you're tackling steep ascents or rugged trails, this feature ensures your poles are always within easy reach. Integrated race bib holders add another layer of convenience, allowing you to attach your bib securely without fuss. Safety and visibility are paramount, and the PX 3.1L excels in these areas with its reflective loops. These loops make it easy to open pockets even in low-light conditions, and they enhance your visibility to others on the trail. The belt is crafted from stretchable, breathable mesh, ensuring optimal ergonomics and superior sweat dissipation, keeping you comfortable throughout your run. For the perfect fit, measure 2 cm below your belly button. It's worth noting that these belts tend to run a bit small, so we recommend opting for the larger size. With the PX 3.1L Trail Running Belt, you can enjoy a hands-free adventure, keeping all your essentials secure and accessible, allowing you to focus on the trail ahead.
