How Absorbency Works

Leak-Lock™ in four slim layers

  1. Quick-wick liner – ultra-soft mesh pulls flow down in under one second.
  2. Absorbent core – technical rayon fleece stores the flow securely (see levels below).
  3. Aquaphobic film – wafer-thin TPU stops pool or sea water from soaking in and keeps odour-causing bacteria out.
  4. Quick-dry shell – recycled nylon / Spandex blend stays light, smooth, and colour-true in chlorine or salt.

Choose the absorbency level that matches your day

Product Light Moderate Heavy
Tampon 1 2 3
Menstrual cup 0.5 1 1.5
Pad 1 2 3
Pantyliner 2 4 6

Tip: on ultra-heavy days, pair with a cup or tampon for the first hour, then wear swimwear solo once flow lightens.

Swim up to 8 hours leak-free, rinse, wash cold, air-dry, and you’re ready for the next dive.

Care Instructions

  1. Rinse in cold water after wear.
  2. Machine-wash cold, gentle, no fabric softener.
  3. Air-dry only—high heat can damage the leak-proof layer.

Tip: a quick rinse at the beach shower keeps colours bright.

Ask the Sisters

Will it leak in the pool?

No. The aquaphobic barrier repels external water while the absorbent core locks period flow inside. The suit stays slim and dry—no swelling or soggy feel.

Can I wear it on heavy-flow days?

Yes. For very heavy flow, we suggest pairing with a menstrual cup or tampon for the first few hours, then wearing the suit solo once your flow lightens.

How long can I swim before changing?

Up to 6-8 hours for light–medium flow. Always rinse and switch to a fresh suit after extended wear for best hygiene.

How do I wash it?

Rinse in cold water, machine-wash on gentle (no fabric softener), then line-dry. Skip the dryer—high heat can damage the leak-proof layer.

How do I pick the right size?

Measure your hips and check our Size Guide above. If you’re between sizes, choose the larger for a comfier swim fit. One free size exchange within 30 days.

Is the fabric safe for my skin?

Yes. We use premium swimwear knits and waterproof films approved for skin contact. No harmful chemical finishes are added.

Will chlorine or salt ruin the suit?

No. The fabric is lab-tested for resistance to chlorine, salt and UV. Rinse after use to keep colours bright and elastic fibres strong.

Love the custom fit. Shortened the straps for extra lift and felt secure through every lap.
