The questions worth asking
Everything you need to know before you try them.
-
A lot of period underwear is built for light days but sold as though it handles everything. Each style is designed for a specific flow and situation — the Night Short for lying down, the High Waist Short for heavy flow, the Period Slip for lighter days. Getting the right style for your flow is what makes the difference.
-
No — this is the thing most people are surprised by. The absorbent layer is thin, sits flat, and wicks moisture away so you don't feel damp. Nothing bunches, nothing shifts. Most customers say it feels closer to normal underwear than anything they expected.
-
Night leaks usually happen because standard underwear doesn't cover far enough at the back. The Night Short has a longer absorbent panel designed specifically for lying down — it stays in place however you sleep. No more waking up to check.
-
It really isn't. Rinse cold, wash at 30°C, hang to dry. No soaking, no special products. A set of four pairs gets you through your full cycle without any mid-week rushing.
-
Period underwear won't change your cycle — but it can reduce how much headspace it takes up. When you trust what you're wearing, you stop planning around the worst case. A lot of customers say they didn't realise how much mental energy their period was costing them until it stopped.
-
Most people spend between £80 and £150 a year on disposables. Four pairs cover your full cycle and last for years — within a few months they've paid for themselves. No monthly shop, no running out at the wrong moment, no waste.
