WUKA Period Swimwear Review: Bikini Briefs, Shorts and Swimsuits Compared

Is WUKA swimwear any good? Yes: WUKA makes some of the most versatile period swimwear in the UK, with leak-proof bikini briefs and high-waist bottoms that hold up to 10ml, swim shorts and swimsuits that hold up to 15ml, and a new Lunafly competition range that holds 20ml for heavy-flow training. Every piece looks like ordinary swimwear, uses chlorine-resistant recycled nylon, and there are matching teen sizes too. In this WUKA swimwear review we line up every piece by absorbency, price and best use, then show you exactly which one to pick for light days and heavy days.
Periods have a habit of turning up right before a holiday, a swim lesson or a beach day. Period swimwear means you no longer have to sit on the side, juggle tampons or plan your plans around your cycle. You just put on your costume and get in the water.
How does WUKA period swimwear work?
WUKA period swimwear has a built-in absorbent gusset hidden inside a water-repellent outer fabric, so it locks period blood in and keeps pool or sea water out. From the outside it looks and feels just like regular swimwear.
The outer fabric is chlorine-resistant recycled nylon, and most of the range also has UV50+ protection and dries quickly. Because the outer repels water, the gusset does not swell up in the pool, which is the clever part that makes swimming on your period feel normal again. WUKA says each piece is reusable for up to two years and saves around 200 disposables from landfill. If you are new to the brand, our WUKA period pants review covers the whole range, from everyday knickers to Drytech.

Which WUKA swim piece should you pick for heavy days vs light days?
For light days and spotting, a 10ml bikini brief or high waist is plenty; for light to medium days, choose 15ml swim shorts or a swimsuit; for heavy days in the pool, the 20ml Lunafly range is the one built for it. Here is a quick way to decide.
Pick by flow and plan
- Light days, spotting, end of your period: Swim Bikini Brief (£21.99) or Swim High Waist (£23.99), 10ml.
- Light to medium days, school swimming: Swim Shorts (£28.99), 15ml, with a modest full-coverage fit.
- Medium days, holidays and lengths: Racerback, Scoopback or Two-Tone Swimsuit (£49.99), 15ml.
- Heavy days and club training: Lunafly Competition suit (£70.00), 20ml, designed to hold your heaviest training day for up to four hours of training.
- Heaviest days on holiday: WUKA suggests its 10ml and 15ml pieces also work as a back-up alongside a menstrual cup or tampon.
A simple combination many families like: one pair of swim shorts or a swimsuit for medium days, plus a bikini brief for the lighter days at the end of the week. That covers a whole holiday without a single tampon.
WUKA bikini briefs and high waist: the light-day favourites
The Swim Bikini Brief is the easiest way into period swimwear: a classic bikini shape, 10ml of protection and sizes all the way from XXS to 6XL. It is rated 5.0 out of 5 on WUKA’s swim page.
The briefs are made with a waterproof outer, chlorine-resistant recycled nylon and UV50+ protection, so they are as happy in a chlorinated pool as in the sea. WUKA designed them to mix and match with any bikini top, to wear under a wetsuit, or under shorts for watersports. Prefer more coverage? The Swim High Waist (£23.99) has the same 10ml gusset, smooth support around the tummy and a high leg cut.
WUKA swim shorts: the modest, full-coverage option
WUKA Swim Shorts hold up to 15ml, around three tampons’ worth, which makes them the go-to for light to medium days and for anyone who wants more coverage. They cost £28.99 in both adult and teen versions.
Shorts are a brilliant pick for period swimming shorts at school swim lessons, pool parties and family beach trips, because they look like ordinary sporty swim shorts and stay put when you are jumping in. They are chlorine-resistant and quick-drying, with the same water-repellent outer that keeps the gusset working in the water.
WUKA swimsuits: racerback, scoopback and two-tone
WUKA’s one-piece period swimsuits all hold up to 15ml, about three tampons or two pads, and cost £49.99. The difference is the cut, so choose the one you would wear anyway.
The Racerback is the sporty one, with a diamond-cut back, a streamlined fit and removable padded cups; the black version is rated 4.8 out of 5 on WUKA’s site. The Adjustable Scoopback has adjustable straps and a clean scoop-back cut for lounging, wild swims and paddleboarding. The Two-Tone versions come in pink/purple and green/blue for a bolder look. WUKA also notes the swimsuits suit light bladder leaks, which makes them a lovely all-rounder for adults.
Lunafly: WUKA’s competition period swimwear
Lunafly is WUKA’s new performance range for serious swimmers, co-designed with three-time Olympian Hannah Miley MBE, and every piece has a 20ml heavy-flow gusset. Suits are £70.00 and sizes run from junior XXS to adult L.
There are three one-piece cuts: the Racerback for club training and galas, the Tie-Back, and the Legsuit with knee-length coverage for colder pools and less ride-up on the blocks. The Lunafly Competition Bikini (£29.99 for the bottoms) is the two-piece option where separates are allowed. WUKA says Hannah co-designed the range because too many girls quit swimming the year their period starts, and that a suit lasts roughly two seasons of regular club training. One tip from WUKA: check your governing body’s rules before senior or elite-level competition.
Period swimwear for teens
Yes, WUKA has a full teen swim range: the Teen Swim Bikini Brief (10ml, £21.99), Teen Swim Shorts (15ml, £28.99), the Teen Racerback Swimsuit (15ml, £49.99) and a Teen Adjustable Bikini Top (£24.99) that grows with them.
For a first swim on a period, the Teen Swim Starter Kits are the easiest buy. Each kit includes the swim piece, a two-pocket wet bag, 20 WUKA wipes, a limited edition swim cap and period-positive stickers, so a nervous swimmer has everything in one bag. Swim shorts are a popular first choice for school because of their modest, full-coverage fit.

How to wash period swimwear
Rinse in cold water straight after your swim, wash cool without fabric softener and always air dry. That keeps the gusset and the chlorine-resistant fabric working for longer.
WUKA recommends washing every swim piece before its first wear. For the Lunafly suits, it says hand washing is best; if you use a machine, pop the suit in a laundry bag on a gentle cold cycle, use eco detergent and never tumble dry. A wet bag is handy for carrying a damp costume home from the pool.
