The Suunto D4i Novo extension strap is perfect for fitting over bulky wetsuits or drysuits and because it simple buckles between the strap ends the extension strap can be added and removed in seconds.

This strap was designed to match the D4i Novo colours but the strap does fit all the D4i variants so if you fancy adding a splash of colour to your computer you can always choose one of these instead.

Please note that the Black strap is the same as the D6i Extension Strap and may be labelled accordingly.
