That is the whole idea, and no fabric can do it if the leg stops at your hip. Bamboo viscose boxers for women in 6 inch and 9 inch lengths, UK 8 to 30, nine colours. £20 a pair or around £13 a pair in a 7 pack, and every size costs the same.
Rated 4.6 from 350 reviews. Free UK delivery, 60 day comfort guarantee, free size swap on your first pair.
Most underwear marketed to women stops between 2 and 4 inches, short of where thighs actually touch. Ours reaches past it.
The second half of the design is the leg band. A band that rolls into a rope at the top of your thigh is worse than no coverage at all, because the rope becomes the thing rubbing. Getting that tension right took longer than anything else we did.
What a great pair of pants, so comfortable. This is my first time trying a longer leg. Planning on buying more.
Full measurements on the size guide, and the first swap is free.
95% Tanboocel bamboo viscose with 5% elastane. Soft from the first wear rather than needing breaking in, breathable and temperature-regulating, and it moves moisture rather than holding it against you. Smooth seams, no tag, dyed to OEKO-TEX Standard 100, which means tested for harmful substances.
Decided to try out bamboo undies, looking for something breathable and sustainable. These are seriously comfortable, the fabric feels so good. Waistband is just the right tightness, you don’t even feel they’re there.
Walking, travel, warm weather, standing all day, under a dress at a wedding. The problem is always the same: skin against skin, and by mid-afternoon the inner thigh is raw. Anti-chafe balm sweats off. Cycling shorts are too hot under a dress. Short cotton boxers roll up within the hour. A long leg in a breathable fabric is the version that works, and it is the only thing we make.
Anti-chafing women’s boxer shorts help reduce friction and thigh rub
Gentle, breathable women’s boxers for sensitive skin
Comfortable women’s boxers for recovery, pregnancy and postpartum days
These are very comfortable and cool to wear. Prevents chafing when wearing dresses. They have been a godsend in this hot weather. They wash well too!
The specification that decides whether boxers stop thigh chafing is the leg length, and it is the one most brands bury. Here is how five of us line up.
| Brand | Leg length | Fabric | Sizing | Per pair |
|---|---|---|---|---|
| Flissie Ours | 6" or 9" | 95% Tanboocel bamboo viscose, 5% elastane | UK 8 to 30, one price | £20, or about £13 in a 7 pack |
| Boody Boyleg | Short boyleg | 79% viscose from bamboo, 15% nylon, 6% elastane | XS to 4XL | £15.95 |
| Thigh Society Cooling | 5" to 21" | Cooling nylon knit with a cotton crotch | XS to 4XL | About £27 |
| TomboyX | 2.5" to 9" | 95% cotton, 5% spandex | 3XS to 6X | About £24 |
| M&S Anti-Chafe | About 5" | Stretch fabric with a touch of cotton. No gusset | 8-10 to 20-22 | About £10 |
Checked against each brand's own product pages in July 2026. We have no commercial
relationship with any of them. Prices move, so treat these as a guide.
The M&S option has no gusset, so it is a slip short worn over underwear rather
than a replacement for it.
We started Flissie in 2021 over something that sounds small and is not: the daily indignity of underwear that rides up, digs in and leaves you sore by mid-afternoon. It is the sort of thing almost nobody mentions and almost everybody puts up with.
We are still a family business, still the two of us. We read every review that comes in, including the ones telling us what we can improve.
Underwear cut with a leg, based on the men's boxer and shaped for a woman's body. Sold as women's boxers, ladies boxers, boxer briefs, boyshorts or trunks depending on the brand. The number that matters is the inseam.
Only if the leg is long enough. A 6 to 9 inch inseam puts a smooth layer between your thighs. A 2 inch boyshort does not reach the point where most thighs touch.
Your normal UK size, 8 to 30. Between sizes, size up.
6 for everyday and under shorter skirts, 9 for long walks, warm weather, sport and under dresses.
Yes. UK delivery is free on every order, and worldwide shipping is available.
