Such Comfort

I have never known such comfortable underwear. Never going back to other types again. Sheer luxury at a fair price.

Jason M. (United Kingdom)

Great underwear, excellent comfort, would like more colours.

Comfiest pants ever

I’ve struggled with finding underwear that doesn’t chafe between the thighs and these are so soft and the way they’re made means the seams aren’t digging in. 100% recommend if you don’t get on with standard knickers x

Shelagh R. (United Kingdom)

I love these boxers, the gusset is very comfortable.
I'm 5'6" size and the medium is great . . . except I have a long back, so the gusset to waist length is a a bit neat for me and pulls. Therefore, might be worth going up a size for me.

Underwear you don't feel during the day because it doesn't move around. Can be worn under leggins and they do not show!
