TRUDIVE Zipper glide skin spring wetsuit Cut Bikini

Product Overview

The Siren bikini wetsuit is what you pull on when the water is warm and a full suit would be one layer too many. It has the lines of a swimsuit — close through the body, long in the sleeve, cut away over the hip — and the warmth of a thin spring suit, which is the combination warm-water divers, snorkelers and surfers keep asking for.

Two millimetres is enough to take the chill off a long session without making a warm dive feel like a sauna. You wear it next to the skin like swimwear, so there is nothing to tuck in, nothing bunching at the shoulder, and nothing extra under a buoyancy jacket or its straps.

Worn as a high cut bikini wetsuit, it clears the hip on both sides, which keeps the leg line free through a kick cycle and stops the suit tugging when you climb back into the boat. The zip runs from a high neck down the chest, so you can close it for a dive and open it on the surface.

Sizing is where most online orders go wrong, so our online diving gear shop lists the standard, short and tall builds side by side. You match the suit to your height and torso instead of ordering the nearest size and hoping.

Product Advantages

• Warmth without weight. A thin neoprene layer holds a film of water that your body warms, so you stay comfortable through a long snorkel or a second dive without the encumbrance of a thicker suit.
• Cut to move. Panels follow the flex lines of the shoulder and hip, so reaching for a mask strap or duck-diving does not drag the suit out of place.
• Glide skin outside. The smooth outer face sheds water rather than soaking it up, and it is dry enough to pull on again after lunch on the boat.
• Entry you can manage alone. As a front zip neoprene swimsuit it opens from the neck down, so you get in and out without help and can vent heat on the surface between dives.
• Cover where it counts. Long sleeves and a high neck keep sun, tank straps and shallow reef edges off the shoulders during long sessions in clear water.
• Travels light. It folds into a day bag, rinses clean in a sink and dries overnight — the kind of suit that earns a place in carry-on rather than the bottom of a dive crate.

Specifications

Fabric & Construction

Every panel is cut to the way a body actually flexes — narrower through the waist, longer through the torso, shaped over the hip — and joined with flatlock stitching that sits level with the surface instead of standing up in a ridge. A flush seam is not a cosmetic detail: it is what keeps a shoulder strap from grinding a line into your shoulder on the second dive of the day.

The titanium coating is applied to the inside of the neoprene. It reflects warmth back toward the body, which is how a suit this thin stays usable across a whole trip, and it also slows the wear that salt, sun and constant stretching put on the material over a season. Looked after properly, the suit keeps its stretch instead of stiffening at the shoulders the way older neoprene does.

The outer face is bare glide skin rather than fabric-covered neoprene, so water runs off it and the suit is quick to dry between sessions. There is no textile layer to hold moisture, which is why it feels light in the hand and packs down small in a bag.

The zip is the part a front zip neoprene swimsuit lives or dies by. Here the opening runs the full length of the chest, with the slider set so it does not press on the sternum when you are lying on a board or hanging at a safety stop, and the pull is big enough to work with cold fingers.

If you are about to buy freediving wetsuit gear, compare the details rather than the headline. A well-made 2 mm suit feels light in the hand, the outer face is uniformly smooth, and the seams lie flat when you run a thumb across them — those three things tell you more about how it will behave in the water than the thickness alone.

Size and Fit

1. Measure yourself in underwear — bust at the fullest point, waist at the narrowest, hip at the widest — and note your height and torso length as well. When you buy freediving wetsuit gear online, those numbers do more for the fit than the size letter does.
2. Match the numbers to the size list. The standard range runs from S to 3XL, and short and tall builds sit alongside it for torsos and legs that fall outside the middle of the range.
3. Expect it to feel firm when you first pull it on. Neoprene should sit close and slightly compressive when dry; it softens with body heat and gives a little once you are in the water, so a suit that feels merely snug on land is usually the right choice.
4. If your bust and hip land in different sizes, take the larger of the two and let the zip do the rest. A suit that is tight at the hip will pull across the shoulder every time you lift an arm.
5. Think about your leg line. The cut is high over the hip, so if you are long in the body a tall build keeps the leg opening where it was designed to sit instead of letting it ride up.
6. Send us your measurements before you finalise the order, especially if you are between sizes or choosing a short or tall build. Two minutes of checking is better than a suit that sits in the cupboard.

Where It Works

• Reef snorkelling and boat days. The Siren bikini wetsuit is cut for a shallow drift over coral: covered shoulders, a leg line that stays clear when you fin, and a collar that keeps spray off your neck on the ride out.
• Warm-water scuba. Tropical reefs and summer diving in mild seas, where a thicker suit is too much on the boat but a swimsuit is not enough at twenty metres.
• Freediving and spearfishing in mild water. Constant-depth training, line dives and shallow hunting; the high cut bikini wetsuit leg keeps the hip free through a duck-dive and the smooth outer face moves with very little drag.
• Mild-day surfing. Waist-high summer swell, longboard sessions and bodyboarding — long sleeves against wax rash, a high neck against the wind on the paddle out.
• Pool training and stroke work. Warm-up sets, breath-hold drills and technique sessions in a heated pool, where a full suit would wear you out before the main set.
• Trips and liveaboards. A week of diving out of one bag: it travels small and rinses in a bucket. If you are flying soon, order early from our online diving gear shop so you can try the fit at home first.

Care and Storage

1. Rinse it in fresh water after every session. Salt, chlorine and sunscreen all sit in neoprene, and a two-minute rinse is the difference between a suit that lasts several seasons and one that stiffens.
2. Wash it occasionally with a little mild soap and cool water. Skip detergents, bleach and hot water, which strip the coating and dull the outer surface.
3. Dry it inside out in the shade. Direct sun is hard on neoprene and on the glide skin finish, and a suit left hanging in the sun all afternoon will feel different by the end of the week.
4. Close the zip before you store it so the tape cannot curl, and rinse the slider every few dives to keep it running smoothly.
5. Store it flat or folded loosely. A tight crease held for months becomes a permanent line, and a damp suit sealed in a hot car is the fastest way to spoil it.
6. Watch your fingernails. Glide skin is smooth and easy to nick, so pull the suit on with the pads of your fingers, and keep sunscreen, tanning oil and rough deck surfaces away from the outer face.

Ordering and Delivery

Start with the options listed in our online diving gear shop and check that your size — including a short or tall build if you need one — and your colour are both available. Stock and timing move with the season, so message our team for the current lead time and the delivery options for your address; we will confirm what is in stock in your size and colour and how long it should take to reach you.

Any duties or local taxes are set by your country's customs rather than by us, so it is worth checking what applies before the parcel ships.

Whether you buy freediving wetsuit gear once for a trip or build a small collection over the years, a sizing question answered now is better than a suit that does not fit. Send your bust, waist, hip, height and torso length if you would like a second opinion before you order.

Use Scenarios

Warm-water diving and snorkeling

In warm seas this wetsuit gives you the thermal protection you need without extra weight getting in the way. The thin neoprene holds warmth close to the body while you swim, kneel over a reef or climb back into the boat, so movement stays easy through a full day in the water. It pairs naturally with the rest of your dive kit, whether you snorkel on holiday or dive regularly.

Surfing and beach days in milder water

When the water is cool rather than cold, this spring suit works as a single layer of insulation that still lets you paddle and pop up freely. The bikini cut and stretchy fabric move with you through paddling out, riding waves and beach games between sets.

If you are not sure which thickness suits the water temperature where you dive or surf, tell us where and when you usually go out and we will point you to the right option before you order.
