Product details
Hera combines a broad single lens with a frameless silicone-to-glass construction. Without a separate outer frame, the lens sits close to the face while the skirt spreads the sealing surface over a relatively wide area.
Bonassi lists the Hera for scuba, apnea and spearfishing. The manufacturer publishes detailed fit geometry, including a 7 cm nose-to-skirt distance and 4 cm nose base, with a 17 cm overall width. Its medium internal volume is a deliberate middle ground: more space than a very low-volume freediving mask, but still compact enough for straightforward equalization and clearing.

Who it suits
A versatile adult mask for divers who want a frameless single lens without going to an ultra-low-volume freediving-only design. Face shape still determines the seal, so the published dimensions are a comparison guide rather than a guarantee of fit.
