The Speedbelt is a collaboration between Zone3 and Nopinz, built specifically for half and full-distance triathlon racing. Wind tunnel and track testing show it saves over 8 watts against a standard race belt and 13 watts over a flapping number. Across a full distance, that equates to around seven minutes. Military-grade elastic replaces traditional buckles for a secure, comfortable fit on the bike and the run. As used by Casper Stornes and Kieran Lindars.
