Product Information

The Mares Jax Mouth Piece (Single) is a heat-moldable, custom-fit mouthpiece built for Mares regulator second stages, sold as a single replacement piece rather than the 12-piece kit. Divers immerse it in hot water and bite down to create a personalized impression for a comfortable, relaxed fit.

Who it is for

This mouthpiece is for divers who want to replace a worn or ill-fitting stock mouthpiece on their Mares second stage with one molded to their own bite. It suits divers who want a mouthpiece molded to their own bite for comfortable, relaxed diving.

Key details

Heat-moldable: soften in hot water, then bite down to form a custom impression of your teeth.
Designed to fit Mares regulator second stages.
Sold as a single piece, as an alternative to the 12-piece multi-color kit.
Available in two sizes, S (Small) and REG (Regular).

Compatibility and sizing

The Jax mouthpiece is intended for Mares regulator second stages. Offered in REG (Regular) in White, Yellow, Pink, Lime, Green, Clear, Blue and Black, with S (Small) available in White, so divers can match or coordinate with their existing gear.

Frequently Asked Questions

What is the difference between the S and REG sizes for the Jax mouthpiece?

The Jax single mouthpiece is offered in S (Small) and REG (Regular); contact us if you are unsure which size to order.

Does the single Jax mouthpiece work with regulators other than Mares?

The Jax mouthpiece is designed to fit Mares regulator second stages. No compatibility with other regulator brands is published by the manufacturer, so divers using a non-Mares regulator should confirm fit before ordering.

How do I mold the Jax mouthpiece to my bite?

Immerse the Jax mouthpiece in hot water for a few seconds to soften it, then bite down firmly to form an impression of your teeth. This creates a customized mouthpiece that guarantees comfortable and relaxed diving.

Does the single Jax mouthpiece include a strap or tie-wrap?

The single-piece Jax listing includes one mouthpiece only. Manufacturer documentation does not specify an included strap or tie-wrap with the single piece, so if you need a replacement strap, check with us before ordering.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.

New to this hanger...Now I'm a believer

Used tons of dive hangers, but never an upside down hanger. Game-changer for me. Will now add more of these in the near-future.

With it's swivel head design, it can cram itself into my tight dive locker, while still donning a ton of gear.

DiveCatalog's "Upside Down Drysuit Hanger w/ Regulator and Accessory Hooks" is a great product with solid construction at an affordable price. All of that with Dive Catalog's customer support/satisfaction guarantee.
