New from Spibelt, the Endurance belt has been designed to be worn in comfort even when the going gets tough, great for long distance runners and mountain biking. All the benefits of a basic Spibelt, but made with heavier gauge materials for extra strength for the longest, toughest endurance races and training sessions. The SPIbelt Endurance Series features a larger neoprene pocket to carry all your race day essentials. With larger elastic (1.5), this SPIbelt is more stable with heavier loads. It also comes with holsters for energy gels and adjustable race bib toggles. Additionally, the SPIbelt Endurance Series is completed with reflective trim for increased visibility.
