Product Information

The Henderson 5mm Thermoprene John is the base layer of Henderson's two-piece john-and-jacket wetsuit system, built from Thermoprene neoprene with GBS-glued and blindstitched seams and a hook-and-loop shoulder closure. It is designed to pair with a matching Thermoprene jacket for divers who want a layered base piece that stands up to repeated use with dive gear.

Who it is for

This John suits men who dive Henderson's john-and-jacket layering system and want a durable base layer that resists wear from BC straps and weightbelts. The Thermoprene material is built to handle that direct contact, so it fits divers who load gear onto the suit dive after dive.

Key details

Thermoprene neoprene offers 75% more stretch than comparable neoprene
GBS-glued and blindstitched seams reduce water entry at the seams
Hook-and-loop closure at the shoulder for on and off access
Spandex trim for a comfortable fit
Freedom Flex kneepads and a spine pad for added comfort and protection

Compatibility and sizing

This 5mm John is designed to pair with a matching Thermoprene jacket as part of Henderson's two-piece layering system. It is available in black in sizes XS, S, M, L, XL, 2XL, and 3XL.

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 Thermoprene John wetsuit?

A John is the base layer piece of Henderson's two-piece system, made from Thermoprene neoprene and designed to pair with a matching Thermoprene jacket.

What thicknesses does the Thermoprene John come in?

The Thermoprene John is available in 3mm, 5mm, and 7mm thicknesses. This listing is the 5mm version, available in sizes XS through 3XL in black.

Do I need a jacket to go with this John?

This 5mm John is designed to pair with a matching Thermoprene jacket as part of Henderson's two-piece layering system. If you already own or plan to add the jacket, the John serves as the base layer underneath it.

Size runs small. Go bigger.

Haven’t had a chance to open water yet. They are tight and seem to run small. I have another brand that bought L and had to return. These I bought M expecting similar, returned and am still tight in the L/XL

Great purchase and "Like New" as advertized.

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.
