Product Information
The Hollis Silicone Dive Mask Strap is a replacement strap made of silicone, built to fit the Hollis M-1 and M-4 frameless dive masks. It carries the manufacturer SKU and MPN 205.4500.STRAP for easy cross referencing when ordering a replacement part.
Who it is for
This strap is for divers who already own a Hollis M-1 or M-4 frameless mask and need to replace a strap that has stretched, cracked, or otherwise worn out over time. It is a straightforward swap-in part rather than a full mask kit, so it suits anyone who wants to keep their existing M-1 or M-4 mask in service without buying a new mask.
