The Nopinz SpeedWallet® is the very latest and most revolutionary solution to carry your race number on your body. Developed by cyclists after extensive research, the Nopinz SpeedWallet® is made from a waterproof breathable material and is available in 3 sizes. The patented design means that there are no exposed edges to catch the wind and slow you down, your race number is safely put inside the wallet which you then stick to your suit. Using Nopinz SpeedWallets reduces drag usually experienced with pinned-on numbers. After use you simply peel the wallet off and throw it away.
