Undie-covering the Love

Reviews we just can’t keep hidden

I have never worn a pair of underwear so comfortable in my life! They wash so easily and return back to their original shape! These undies are a game-changer!

Can confirm, my most comfortable underwear ever. I wore it on a 27-hour journey from Europe back to Australia and they felt amazing the whole way. Cannot recommend enough. back to their original shape! These undies are a game-changer!

The fit and feel of the merino wool is wonderful. They're lightweight, breathable and don't pinch in any areas and create those awful panty lines through your clothes. Love them!!

I'm a complete Merino wool convert - the odor and moisture control is remarkable. For those comparison shopping, I have tried a couple of the competitors and these are better.

I LOVE these underwear!! I have super sensitive skin and these are non irritating and oh so comfortable.
