Product Information
The Seac Strap Full Face is a genuine replacement elastic fabric strap built for the Seac Unica and Magica series full face snorkeling masks, designed to restore the original fit when the strap wears out, stretches, or is lost.
Who it is for
This strap is for snorkelers and divers who already own a Seac Unica or Magica full face mask and need a factory-matched replacement part rather than a universal substitute. It suits anyone whose original strap has degraded from sun and saltwater exposure, or who simply wants a spare on hand for travel and rental fleets.

Compatibility and sizing
This strap is built specifically for the Seac Unica full face mask series and the Seac Magica full face mask series. It is not a generic strap, so confirm your mask model before ordering to be sure the fit matches the original equipment.
