Poseidon 3D Mask ThreeDee Doubleglass Low Volume Mask

Quick answer: The Poseidon 3D (ThreeDee) Doubleglass is an ultralight, low-volume two-lens mask with a robust polymer frame, a high-quality silicone comfort-fit skirt and side buckles that swivel 45 degrees. Poseidon says it fits most faces.

Why bigger divers look at it

"Fits most faces" is a broad claim, but the comfort-fit skirt and 45-degree swivel buckles give you room to set the strap where it's comfortable on a larger head instead of where the frame dictates. The buckles are strong and easy to adjust. Poseidon doesn't give a specific face-size rating, so the fit test below is your best guide.

What it does well

The ultralight polymer frame keeps weight off your face while staying sturdy. Low volume makes clearing and equalizing simple, and the two-lens layout is a familiar, dependable design for scuba and snorkeling. It also travels light.

What you get

• Ultralight two-lens design
• Robust polymer frame
• Low internal volume
• High-quality silicone comfort-fit skirt
• Strong side buckles that swivel 45 degrees

Before you buy

Hold it to your face without the strap and breathe in gently through your nose. It should stay put without pressure at your temples or nose pocket. Read How to Fit a Dive Mask. More options: Wide-Fit Scuba Masks for Larger Faces.
