Our favourite for a 3 mm brief thanks to glued and blind-stitched seams and reinforcement at stress areas.

The men’s Fast 7 mm is a double-lined full wetsuit with Ultra-Span arm panels, shaped legs and a YKK back zip. Inner cuff rings and a GlideSkin backing under the zipper are intended to limit flushing. It is the thicker Fast option to investigate when the 5 mm version does not provide enough protection for your planned dives.

This is BARE’s original women’s 5 mm Nixie full suit, SKU 002469, now listed in its outlet range. The manufacturer describes a proprietary neoprene blend and a women’s cut. It is a different listing from Nixie Ultra and the newer Ultra 2.0; the similar names can easily lead to the wrong review or specification.
Check before buying: The current outlet page supplies little construction detail. Confirm the zipper, seams and lining on the actual stock before buying, and do not assume it has the mineral-based lining described in Nixie Ultra reviews. Clearance pricing is only useful when the suit fits and the seller’s return conditions work for you.

The women’s Fast 1 mm provides full-length coverage in a thin double-lined neoprene suit. Its pre-shaped leg panels, elastic lining and reinforced knees are intended to preserve movement without the bulk of thicker Fast models. The back zipper and shaped neck closure include barriers intended to reduce flushing.
Check before buying: Check the women’s chart and actual torso fit rather than translating a size from the men’s suit. A 1 mm suit leaves limited thermal margin for long or repeated dives. Retail listings inconsistently describe an open-cell interior, while Cressi specifies lining on both sides; we use the manufacturer’s construction description.

The men’s Fast 1 mm is the thin, full-length member of the Fast range. Double-lined neoprene, pre-shaped legs and reinforcement at the knees provide coverage with less bulk than the 5 and 7 mm versions. Its rear YKK zipper has an internal barrier intended to limit water entry.
Check before buying: One millimetre offers little insulation compared with thicker Fast suits, so choose it for genuinely warm conditions rather than borrowing temperature claims from other thicknesses. Some retailer reviews attached to the 1 mm listing explicitly discuss a 7 mm suit. Those mixed-product stars are excluded, and the manufacturer’s double-lined description takes precedence over conflicting open-cell retailer labels.

The men’s Fast 5 mm combines double-lined neoprene with stretchy arm panels and shaped legs. It has a back zipper with a GlideSkin backing and internal sealing rings at the wrists and ankles. This makes it a useful temperate-water fitting option if you prefer a straightforward full suit over a hooded semidry.
Check before buying: ScubaLab found the close fit effective against water movement, but reported some effort getting the suit on and off. That is a more useful consideration than assuming every stretchy suit is effortless to dress in. Check cuff comfort, torso length and shoulder reach with the zip closed. The test’s Best Buy award is not a numeric overall grade.

Inner cuff rings and a GlideSkin backing under the zipper are intended to limit flushing. It is the thicker Fast option to investigate when the 5 mm version does not provide enough protection for your planned dives.
Check before buying: Check shoulder reach and torso length carefully; a thicker suit that fits poorly can still flush. ScubaDownUnder rates the Fast 7 mm at 4/5 and reports warmth alongside mobility and drying-time compromises. ScubaLab’s separate 2022 test was more positive about flexibility, illustrating why published opinions do not replace a fitting.

The women’s Velvet is a 3 mm full suit with a diagonal front zipper running from the waist towards the shoulder. Its double-lined Ultrastretch neoprene and flatlock seams are intended for flexible warm-water coverage. Hydrosealing wrist and ankle cuffs and an uninterrupted front neck section are its main distinctions from a conventional back-zip suit.
Check before buying: Try the zipper reach and shoulder movement on the women’s cut before buying. Flatlock seams are not the same construction as glued and blind-stitched seams, and cuffs cannot guarantee warmth when the torso fit is loose. A published scored article found during research covers Velvet Man, so its rating is not transferred to this women’s version.

The Junior’s Back Zip Jumpsuit is Henderson’s full-coverage Thermoprene option in junior sizes 10–16. The manufacturer distinguishes A830JB at 3 mm from A850JB at 5 mm. Glued-and-blindstitched seams, an adjustable collar, spine pad and flexible knee reinforcement are useful details for regular diving use.
Check before buying: The two thicknesses are separate choices, not interchangeable specifications. Check the exact SKU, fit at the neck and torso, and movement with the intended equipment. The official image shown is labelled A830JB; it should not be taken as confirmation of a 5 mm order.

The 3 × 3 GBS is a full suit with 3 mm neoprene throughout, glued and blind-stitched seams, and internal tape at main stress areas. Stretch panels cover the shoulders, arms and sides. O’Three also adds a floating collar, internal zipper guard and reinforced knee and seat areas.
Check before buying: Compared with a shortie, the full suit provides more coverage but needs a careful check of leg length and shoulder reach. Men’s and women’s cuts are listed separately. A manufacturer-hosted field account praises its knee protection and construction, but it is promotional evidence rather than an independent numeric assessment.

The men’s SSMC is Sherwood’s Marine Conservation 5 mm full suit, using Quantum Stretch neoprene with glued and blind-stitched seams. Abrasion-resistant knees and a rear zipper with a long pull cord are the principal practical features. The men’s version uses its own sizing and a topographical graphic rather than the women’s wave pattern.
Check before buying: ScubaLab liked the fit, movement and sealing of the Marine Conservation model in its 2024 test. Its Testers Choice award is not an overall numeric rating, and individual fit remains decisive. The conservation positioning also does not establish a specific donation per purchase unless the seller supplies those terms.

The women’s SSMC is a 5 mm back-zip full suit made from Quantum Stretch neoprene. Its wave graphics distinguish it from the men’s version, while glued and blind-stitched seams and reinforced knees provide a straightforward construction. The women’s size chart should be checked independently of the men’s range.
Check before buying: DIVEIN’s tester found comfortable mobility, a manageable collar and little flushing, but wanted more features and clearer information about conservation donations and production standards. Those observations are useful buying context, not a guarantee of fit. The accessible review gives a recommendation without a numeric overall score.

NEOSKIN is Waterproof’s thin, full-length neoprene suit. The current official page specifies 1.5 mm material, a back zipper, flatlock seams and thumb and foot loops. Its seam-free crotch and stretchy construction target easy movement and dressing rather than the insulation of a much thicker suit.
Check before buying: Several retailer listings found during research describe a 1 mm NEOSKIN. Confirm the thickness and generation supplied rather than treating those older customer reviews as tests of the current 1.5 mm listing. Wind- and splash-resistant fabric does not make the complete suit a drysuit.

The W20 is a 2.5 mm wetsuit made from stretchy Aquatex neoprene. Waterproof positions it for warmer water, where a light full suit can provide coverage without the bulk of its 5 mm models. Its appeal is straightforward: a flexible, close-fitting suit for divers who do not need a thick exposure layer for the planned conditions.
Check before buying: A thin suit leaves less thermal margin on repeated dives, and a loose fit can allow water exchange even in warm water. Test the shoulders and neck while reaching forward and overhead. Do not treat the thickness as a guarantee of comfort throughout a liveaboard trip; dive duration and personal cold tolerance still matter.

The W40 is Waterproof’s blue 5 mm full wetsuit, built from Ultraflex neoprene and fitted with a hip pocket. It is aimed at temperate-water diving, with a close fit intended to reduce flushing. The pocket is a useful distinction from simpler full suits when you want somewhere to stow a small item without adding a separate pouch.
Check before buying: Fit around the lower back, neck and cuffs matters more than the colour or the stretch claim. Check that the pocket remains accessible with your BCD and does not pull awkwardly when loaded. Waterproof’s thermal claims do not establish a personal minimum water temperature, particularly for long or repeated dives.
