Reviews

Bit loose

"Shorts itself are a bit loose and there's just so much fabric around the waist / hip that I'm always hoisting up the waistband. Aside from that, a comfortable pair of pants."

— Cher L. (4/5)

Comfy and fits well

"Very soft, does not dig in like some other brands. Would only be better if the entire garment was sustainable materials"

— Chanel C. (4/5)

Comfortable

"I like them a lot , I do agree with some of the other reviews that there is a sort of 'bulkiness' to them , something that could be improved around the gusset area , though, also agree that they're some of the most comfy on the market , soft and don't dig in as much as others where the stitching is etc . And I like that the only synthetic is nylon , that's the most natural one I've found so far that's super comfortable too as most have some polyurethane layer in the centre which these don't ."

— Beth (5/5)

Very comfortable and reliable

"Would prefer if the design came all the way up the back for full coverage to sleep in but otherwise everything else was perfect"

— lara s. (4/5)

Ok but not the best

"Ok but not the best period pants or boxers I’ve had. The liner but is very stiff and bulky. Tho overall it is soft"

— Sarah (3/5)

Comfortable enough

"Kinda bulky, but comfortable enough"

— Neridah L. (4/5)

Very comfy

"I was tossing up between size M and L, and decided to go with size L. The full briefs fit perfectly in a L, but in this style the L is a little baggy on me. However, I still feel supported, and the most important thing for me was finding period undies that are soft, breathable and don’t cut in, that I can wear with a cup or disc, and these are perfect for that."

— Belle (5/5)

So comfortable I forgot I

"So comfortable I forgot I was wearing period undies!"

— Rachel C. (5/5)

Best bra ever

"So comfy"

— GEORGIA B. (5/5)

Best period undies I’ve owned!

"These feel so secure. The fabric is nice and soft. They actually hold the blood and don’t leak. I’ve tried lots of brands and these are the best so far :) bonus points for being non toxic!!"

— Mia D. (5/5)
