Step One has never been shy about shaking up the underwear drawer, and this time, they’ve set their sights on period protection. The pioneering brand has unveiled a new period underwear line designed to feel exactly like the breathable, bamboo-soft Step One favourites people already love — but with a clever two-layer absorbent core that trades bulk for brains.
For years, traditional period underwear has felt more like a mattress topper than actual underwear — thick terry cloth, stifling layers, and comfort levels somewhere between “meh” and “medieval.” Step One’s latest innovation changes all that with an integrated absorbent knit that combines absorbency and waterproofing in a single layer.
The result is a feather-light, slimline fit that dries faster, breathes better, and still keeps everything firmly locked in place.
The technology beneath the surface
Step One’s new range relies on a smart three-layer structure:
- Top Layer – Naturally Hygienic Wool Jersey: This sits directly against the skin, wicking moisture, regulating temperature, and managing odour. Even on heavy days, it keeps things dry and comfortable.
- Second Layer – Absorbent Core Knit with Leak-Lock Barrier: A bonded polyester/cotton knit and TPU membrane draw fluid in, spread it evenly, and lock it away. Think discreet protection without the puff.
- Outer Layer – Durable Bamboo Shell: This soft, stretchy layer (95% certified bamboo viscose, 5% elastane) delivers that familiar Step One fit — breathable, hard-wearing, and ready for frequent washes.
The range at a glance
- Step One Period Thong
For light flow days, spotting, or just a little extra backup. It’s the barely-there option that doesn’t skimp on protection. - Period Bikini Brief
The everyday hero. It mirrors Step One’s best-selling Bikini Briefs but with absorbent superpowers — slim, supportive, and built to handle workdays, weekends, and workouts without the dreaded bulk. - Period Full Brief
Made for the big days and long nights. This version extends the absorbent panel through the back for extra coverage while staying sleek. It’s ideal for overnight protection or heavier flow days — slim protection, no compromises.
A shift forward
Step One’s message is simple: periods shouldn’t mean padding, bulk, or discomfort. With this new line, the brand invites wearers to “switch to Step One and step forward with less. FLOW FORWARD.”
