Bare Nixie Ultra 5mm Women’s Full Wetsuit

Bare 5mm Nixie Ultra Women's Full Wetsuit: A Warm-Water-to-Cool-Water Suit Built for the Female Form

The Bare 5mm Nixie Ultra is a full-length women's wetsuit made from 5mm neoprene, cut specifically for a woman's body and packed with thermal features designed to keep you warmer, longer.

If you are a recreational diver who finds yourself cold before your dive buddy, or if you have been making do with an ill-fitting unisex suit, this is worth a serious look.

What "5mm Full Suit" Actually Means for You

Five millimetres of neoprene is the sweet spot for cooler recreational diving, typically comfortable in water temperatures where a thinner suit leaves you shivering by the second dive.

A full suit covers everything from wrists to ankles, so there are no gaps at your core, the area where you lose heat fastest.

If you dive warm tropical water regularly, a 5mm full suit may feel like too much. This thickness is aimed at divers who regularly encounter cooler conditions, or who simply run cold regardless of the water temperature on paper.

The OMNIRED Technology: What It Is and What It Does

Bare weaves 13 thermo-reactive minerals into the fabric of the Nixie Ultra. These minerals work by capturing the infrared energy your body naturally radiates outward and reflecting it back toward you.

The practical result is that your own body heat does more work. Bare states that this process has been validated in scientific studies and that improved circulation from infrared energy allows your body to use less effort to stay warm, which can translate to more time in the water before the cold forces you out.

This is not a heating element or a battery-powered system. It is a passive technology built into the neoprene fabric itself, so there is nothing to charge or maintain.

Fit and Flexibility

The Nixie Ultra uses Bare's Progressive Full-Stretch construction, which places varying degrees of stretch neoprene across different zones of the suit rather than using a single uniform fabric throughout.

In practice, this means the panels that need to move most, around your shoulders, knees, and hips, are cut to flex with you. The result is a suit that should not fight your movements when you kick, reach for your equipment, or adjust your position in the water.

The suit is also cut specifically for the female form, not a scaled-down version of a men's pattern. For women who have struggled with excess volume in the torso or a poor fit through the hips in unisex suits, that distinction matters for both comfort and thermal performance. A suit that fits properly flushes less cold water through the interior.

Getting In and Out

Donning a 5mm wetsuit can be a workout on its own. The Nixie Ultra addresses this with several access points:

• Back zipper: 19 inches (48.25 cm) long with a pull-tab leash so you can reach it yourself without a dive buddy.
• Wrist zippers: let you slide your hands through without wrestling the cuffs.
• Ankle zippers: same idea for your feet, making the lower legs much easier to manage.
• Front neck zipper: adds comfort at the collar area and helps with the final fit around your neck.

The collar also uses a hook-and-loop adjustment with a booklet-style suit saver, which protects the neoprene from the hook material catching and tearing during closure.

Sealing Out Cold Water

Warmth in a wetsuit depends not just on thickness but on how well the suit keeps cold water from flushing through. The Nixie Ultra addresses this in a few specific ways.

The collar uses a Glideskin finish, a smooth, skin-contact neoprene that forms a close seal against your neck to reduce flushing at the top of the suit.

At your wrists and calves, internal skin-in flip seals at mid-forearm and mid-calf create a secondary barrier against water entry at the openings.

The seams themselves are double-glued with Secure-Lock construction, which bonds the panels from both sides and eliminates the gaps that stitched-only seams can leave. Less water gets in through the seams, and what warmth you generate stays with you longer.

Durability and Comfort Details

The knees are reinforced with Armor-Flex kneepads, which protect against abrasion when you kneel on a boat deck, a rocky entry point, or a sandy bottom.

The underarms are seamless, which matters more than it sounds. A seam running through the armpit can chafe badly over a long dive or a multi-dive day, especially when worn under a buoyancy compensator. Removing that seam entirely solves the problem before it starts.

The suit is black with your choice of pink or blue accents and is available in multiple sizes.

Is This the Right Suit for You?

The Nixie Ultra is a strong fit if you are a recreational diver who dives cooler water, runs cold, or simply wants a women's-specific suit that combines genuine thermal performance with a cut that actually fits.

If you dive warm tropical water exclusively and rarely feel cold in the water, a 5mm full suit is likely more than you need and may feel restrictive in the heat.

If you are looking for a suit that layers well, the seamless underarms make it compatible with a wet layer underneath or a BCD on top without the friction points that plague suits with underarm seams.

For the diver who has settled for a suit that fits "well enough," the Nixie Ultra is a case for not settling.
