Henderson 7mm Thermoprene Women’s Full Wetsuit

Henderson 7mm Thermoprene Women's Full Wetsuit: A Cold-Water Full Suit Built for Recreational Divers

The Henderson 7mm Thermoprene Women's Full Wetsuit is a full-length neoprene suit designed to keep you warm in cooler water, with a cut made specifically for a woman's body.

If you are a certified recreational diver planning dives in colder conditions and want a well-constructed suit without paying top-tier prices, this is worth a serious look.

What "7mm" Actually Means for You

Wetsuit thickness is measured in millimeters of neoprene. Seven millimeters is on the thicker end of the recreational wetsuit range.

That thickness is appropriate for cooler and cold-water diving. If most of your diving happens in warm tropical water, a 7mm suit will likely be too warm and too restrictive. This suit is built for divers who regularly encounter colder conditions, not for Caribbean reef dives.

The Thermoprene Material

Henderson builds this suit from what they call Thermoprene, a nylon-2 neoprene construction. The key practical difference from standard neoprene is stretch.

Standard neoprene can feel stiff, especially at 7mm. The Thermoprene material gives you 75% more stretch than standard neoprene, which matters most when you are pulling the suit over your shoulders and around your torso. Getting into a thick wetsuit is one of the more exhausting parts of a dive day, and this material genuinely reduces that effort.

It is worth being direct about where this material sits in Henderson's lineup. The Thermoprene is more flexible than a basic neoprene suit, but it is not as stretchy as Henderson's Thermoprene Pro or TherMAXX lines. If maximum flexibility is your priority, those suits sit above this one. If you want a meaningful upgrade from standard neoprene at a more accessible point in the range, this is the right level.

The exterior laminate is also worth noting. BC straps and weight belts grind against the outside of a wetsuit on every dive. The pill-resistant and abrasion-resistant outer fabric on the Thermoprene holds up to that wear better than plain neoprene surfaces.

Seam Construction

At 7mm, seam quality matters more than it does on a thinner suit. Cold water finds its way in through poorly sealed seams, and once it does, your body has to work harder to warm it back up.

The Henderson Thermoprene uses glued and sewn seams. Gluing closes off the stitched channel so water cannot track through the needle holes. Sewing adds structural strength so the seam holds under the stress of repeated stretching. Together, they reduce water entry significantly compared to stitched-only construction.

Fit and Comfort Details

The suit is cut specifically for women, not adapted from a unisex pattern. That distinction matters for how the suit fits across the shoulders, chest, and hips, and ultimately for how well it seals and how comfortable it is over a full dive day.

A few details that contribute to day-to-day comfort:

• Spandex-trimmed cuffs at the wrists and ankles create a softer seal against your skin and reduce chafing.
• Wrist zippers make it easier to get the suit on and off without fighting the tight lower sleeves.
• An adjustable collar lets you tune the neck fit, which affects both comfort and how much cold water flushes in at the surface.
• A self-sealing spine pad runs over the back zipper. It limits water exchange through the zipper channel and also cushions the pressure of a tank against your spine during the dive.
• Freedom Flex kneepads protect the knees with a tougher exterior material while maintaining enough flex that kneeling on a boat or reef wall does not feel locked up.

The Zipper

The closure is a #10-YKK back zipper with a pull tab leash. YKK is a widely trusted zipper manufacturer, and the #10 size is a heavy-duty rating. The pull tab leash means you can reach the zipper yourself rather than always needing a buddy to help you in or out of the suit. That is a small thing that makes a real difference at the end of a cold dive.

Is This Suit Right for You?

The Henderson 7mm Thermoprene is a solid choice if you are a recreational diver who:

• Dives regularly in cooler or cold water and needs real thermal protection
• Wants noticeably better stretch than a basic neoprene suit without moving to a premium-tier material
• Values glued and sewn seam quality at this level of the market
• Prefers a suit designed around a woman's fit rather than a modified unisex cut

It is probably not the right choice if you dive primarily in warm water, if you need the highest possible flexibility for technical or demanding recreational profiles, or if you are looking for a drysuit-level thermal barrier. For cold-water recreational diving with a focus on durability and a proper fit, the Thermoprene earns its place.
