How Bare measures

Wear minimal clothing (ie. T-Shirt, shorts, bathing suit) at the time of measuring. All measurements must be taken with a soft tape measure pulled snug but not tight. Stand straight, looking forward with your feet flat on the floor. It is best to have help taking the measurements, in order to remain in the optimal measuring stance.

Weight: As close as you can accurately.
Height: From the top of your head to the floor.
Chest: Measure around the fullest part.
Waist: Measure around the narrowest part.
Hip: Measure around the fullest part.
Torso: Top of shoulder to crotch vertically.
Inseam: Measure from crotch to floor.

Product Information

The BARE 3mm Sport John is a men's sleeveless, full-length "John" style wetsuit built from 3mm N2S neoprene, designed to layer under a 7mm or 3mm step-in jacket for a modular warmth system. It combines a heavy-duty front zipper, DURASHIN lower leg protection, and Armor Flex knee protection in a sleeveless cut that offers freedom of movement for layering purposes.

Who it is for

This suit suits divers and watersports users who want a layering base rather than a single fixed-thickness suit. The Sport John pairs with a 7mm or 3mm step-in jacket for added warmth.

Key details

3mm N2S neoprene construction throughout the suit
Heavy-duty front zipper for a secure, repeatable seal
Heavy-duty ankle zippers that ease donning and doffing, including with gloves on
Double glued and Mauser stitched seams for durability and watertight performance
DURASHIN lower leg protection against abrasion from rocky or reef contact
Armor Flex knee protection to extend the suit's service life at a common wear point

Compatibility and sizing

The Sport John is designed to layer with either a 7mm or 3mm step-in jacket. It is available in SM (Small), M (Medium), ML (Medium Large), L (Large), XL (X-Large), 2XL (2X-Large), and 3XL (3X-Large), and is offered in black.

Frequently Asked Questions

How should a wetsuit fit?

A wetsuit should feel snug everywhere, with no loose pockets at the lower back, armpits, or behind the knees where water can collect and flush. It will feel tighter than normal clothing on land, which is expected, because the suit works by holding a thin layer of water that your body warms. If you cannot take a full breath or the neck chokes you it is too small, and if you can pinch loose folds of neoprene it is too big.

What do you wear under a wetsuit?

Most divers wear a swimsuit, a rash guard, or a thin dive-specific base layer under a wetsuit. A slick base layer makes a tight suit much easier to pull on and cuts down chafing at the neck, shoulders, and underarms. Avoid thick cotton clothing, which soaks up water, bunches, and makes you colder rather than warmer.

How do you put on a tight wetsuit?

Work upward in small sections, pulling a little neoprene at a time rather than yanking on one spot, and get the suit fully seated at the ankles and knees before working on the hips and shoulders. A plastic bag over each foot and hand, or wetting the suit first, helps it slide into place. Grip with flat palms rather than fingertips, since fingernails are the most common cause of torn neoprene.

Does a thicker wetsuit mean a warmer wetsuit?

As a general rule, thicker neoprene insulates more, so a higher millimeter rating is warmer in the same conditions. Warmth also depends heavily on fit, suit style, seam construction, whether you add a hood, boots, and gloves, how long the dive is, and your own cold tolerance, so two divers in identical suits can feel very differently. Use thickness as a starting point and refine it against your local conditions and personal experience.

How do I care for and store a wetsuit?

Rinse it inside and out in fresh water after every dive day, and use a wetsuit-specific wash occasionally to control odor. Dry it inside-out first and then flip it, always out of direct sunlight, because UV and heat break down neoprene faster than anything else. Store it hanging on a wide-shouldered hanger or laid flat rather than folded, so you do not set permanent creases.

How long does a wetsuit last?

Lifespan depends far more on use and care than on age, so a suit dived hard in sun and chlorine may soften within a couple of seasons while a well-rinsed occasional-use suit can last many years. Signs a suit is finished include compressed neoprene that no longer feels buoyant or warm, splitting seams, and looseness in areas that used to be snug. Repairing small cuts and seam separations early adds meaningfully to a suit's life.

What is the difference between a full suit, a shorty, and wetsuit separates?

A full suit covers arms and legs, a shorty stops at the upper arms and thighs, and separates such as tops, bottoms, and hooded vests layer to add warmth where you want it. Layering a vest or top under a full suit adds core warmth and can extend the range of a suit you already own. Choose based on how much coverage you want, both for warmth and for protection against stings and abrasion.

What is a "John" style wetsuit?

A John style suit is sleeveless with full-length legs; this one is built to layer under a 7mm or 3mm step-in jacket. The BARE 3mm Sport John is built this way specifically to pair with a 7mm or 3mm step-in jacket.

Can the BARE 3mm Sport John be worn without a jacket?

BARE designed the Sport John for layering, pairing it with a 7mm or 3mm step-in jacket for added warmth. For cooler water, it is designed to layer under a 7mm or 3mm step-in jacket, which adds core warmth while the John continues covering the torso and legs.

What is Armor Flex knee protection?

Armor Flex knee protection reinforces the knee area to extend suit longevity, working alongside DURASHIN lower leg protection.

What sizes does the BARE 3mm Sport John come in?

The BARE 3mm Sport John is offered in SM (Small), M (Medium), ML (Medium Large), L (Large), XL (X-Large), 2XL (2X-Large), and 3XL (3X-Large), all in black. If you are between sizes or unsure how it will layer with a step-in jacket, DiveCatalog.com can help confirm fit by phone or chat.

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.
