The Seal mask by Tech Pro was specifically created for spearfishing and free diving. Made with Frameless technology (direct injection of silicone into the glass) and without a frame, it is a lightweight, durable, and easily storable mask. The small internal volume, equivalent to about 94ml, contributes to easier cleaning, as well as to the balance of internal pressure, performing excellently at great depths. In addition, the small distance between the eyes and the Tempered glass lenses provides a panoramic field of view with excellent peripheral vision without the existence of blind spots.

Internally and peripherally, it features a rim that aids in creating a seal and also provides relative rigidity when diving deeper. Two small "valleys" on both sides of the nose pocket help prevent excessive distortion of the frame when compressing the nose with fingers for pressure equalization.

The strap buckles, made of POM material, are ergonomically designed with double buttons and cylinders that allow for easy and precise strap adjustments. Lastly, the dual-strap silicone band enables the placement of the snorkel at the back of the head, avoiding intense vibrations during diving and resurfacing phases.
