Mares Spyder Spearfishing and Freediving Mask

Mares Spyder Spearfishing & Freediving Mask: Low-Volume Mask Built for Breath-Hold Diving

The Mares Spyder is a twin-lens, low-volume freediving and spearfishing mask designed for adult breath-hold divers who need reliable vision, a secure seal, and easy equalization at depth.

If you are regularly hunting fish on a single breath or pushing your freediving deeper, this mask is built around the things that actually matter at that level.

Why Low Volume Matters for Freediving

When you freedive, you carry only the air in your lungs. Every air space in your gear, including the inside of your mask, needs to be equalized as you descend by exhaling a small amount of air into it through your nose.

A mask with a large internal air space costs you more of that precious breath. The Spyder is built with minimal internal volume, so equalization takes less air and less effort. That is a genuine advantage on deeper dives and long sessions.

The low-profile construction also keeps the mask close to your face, which reduces drag as you move through the water. Over a long dive, that matters.

Fit and Seal

The Spyder is sized for a regular adult fit and uses a silicone skirt to form a watertight seal against your face. Silicone conforms well to different face shapes and holds its seal better over time than older rubber skirts.

The facepiece is anatomically shaped, meaning it follows the natural contours of the face rather than forcing a flat fit. Combined with a soft nose pocket, this matters most during long water sessions where a stiff or poorly shaped mask starts to press and fatigue.

The skirt profile is described as hydrodynamic, sitting close and streamlined rather than flaring out. That keeps resistance low when you are swimming hard after fish or pulling down on a line.

Vision

The Spyder runs two lenses side by side. A twin-lens design allows for a wider horizontal field of view than a single flat lens, which is useful when you are scanning for movement in open water or tracking fish in low-visibility conditions.

The lenses have a matte, anti-reflective finish on the frame and surrounding surfaces. This reduces the kind of glare that can wash out your view near the surface or in bright, shallow water. It is a small detail, but one that experienced spearfishers notice when the light angle is awkward.

Equalization at Depth

Equalizing your mask at depth requires pinching your nose and blowing gently. The Spyder makes this straightforward with side knobs and a raised grip on the nose pocket, giving you something to hold onto even with thick gloves or cold, numb fingers.

This is a practical detail. On a deep breath-hold dive, you want to equalize quickly and without fumbling. A nose pocket that is easy to grip through a 3 or 5mm glove is worth having.

Who This Mask Is For

The Spyder suits spearfishers and freedivers who are already comfortable in the water and want a mask that keeps up with them. It is not a general snorkeling mask or a scuba mask. The low volume and close fit are advantages specifically in breath-hold diving and would feel unnecessarily restrictive to a casual snorkeler.

If you are new to freediving and still figuring out equalization, the Spyder's easy-grip nose pocket and low air volume will actually help you learn the skill with less frustration.

If you freedive with prescription needs, confirm whether corrective lens options are available for this model before you buy.
