WUKA

WUKA: Reusable period underwear with capillary absorbency technology

WUKA is a British brand specializing in reusable, washable period underwear, presented as an alternative to tampons, pads, and menstrual cups. The company sells its products through its online store, with shipping to various countries and regions, and caters to both adults and teens.

The company states it has received awards and been featured on the BBC, and claims to have over one million customers. Its catalog is organized by flow type, style, and collection, and also includes period swimwear and wellness items.

How period pants work

According to the brand, its period pants use a multi-layer system that absorbs flow through capillary action. A quick-drying top layer directs liquid into a porous absorbent core that spreads and stores it; a breathable, leak-proof barrier prevents leaks. The company states the system keeps skin dry and protected for up to 12 hours.

WUKA notes that its breathable fabrics, such as Tencel™ and organic cotton, promote air circulation and help prevent odors without relying on harsh antimicrobial products or silver. The quick-drying top layer maintains a dry feel, and the brand recommends pre-washing the pants three to four times before first use to activate the absorbent fibers.

Absorbency levels

The catalog classifies products by how much flow they can absorb:

• Light flow: 5-10 ml, equivalent to 1-2 tampons, for light spotting or light flow.
• Medium flow: 15 ml, equivalent to 3 tampons, for moderate flow days.
• Heavy flow: 20 ml or more, equivalent to 4-5 tampons, for heavy flow or overnight use.
• Super heavy flow: 60 ml, equivalent to 12 tampons, for postpartum, extreme flow, or long shifts.

Styles and collections

The brand offers a variety of styles including midi briefs, boxer shorts, high waist, hipster, bikini, thong, swimwear, cycling shorts, and sleep or overnight wear. It also sells maternity and postpartum styles, as well as a specific line for girls and teens.

Collections are grouped under the names Stretch™, Ultimate™, Perform™, Basics™, and Lunafly™. The brand sells 3, 5, and 7 packs, and complements its offering with vitamins, pain relief products, cycle sets, and accessories.

Period swimwear

WUKA also makes period swimwear designed to absorb flow during swimming. The line includes styles for adults, teens, and a competition version. The company presents them as a solution for the next generation, without the need for pads or tampons.

Teen and first period line

The brand has a specific section for girls and teens that includes period pants, swimwear, first period starter kits, school sets, period books for teens, accessories, and cycle care vitamins. The featured Teen Stretch™ product is offered at £12 per pair, with a 3 for £36 promotion.

Wellness and accessories

In addition to underwear, WUKA sells wellness products such as heat patches, iron gummies, and other items for menstrual discomfort relief. The company notes that while period pants do not directly reduce uterine contractions, their soft, non-restrictive materials improve overall comfort, and recommends external heat therapy to soothe cramps.

International shipping and online presence

WUKA's online store allows selecting country or region and currency, with options including the United Kingdom, United States, Canada, Australia, Ireland, Italy, Switzerland, Guernsey, Isle of Man, Jersey, and New Zealand. The company offers free shipping, a 40-day free trial, and programs such as WUKA for Education, sports sponsorship, the option to become a stockist, ambassador, student and community discounts, disabled discounts, and NHS staff discounts. The company identifies as a Certified B Corp.
