Product Information
The Suunto DX Black Silicone With Black Buckle Extension Strap extends the wrist strap of a Suunto DX, D9tx, D6i or D6 so it fits over a wetsuit or dry suit. Made from black silicone and fitted with a matching black buckle.
Who it is for
This extension strap is for divers whose factory wrist strap is too short to fit over a wetsuit or dry suit sleeve.
