Good for lighter days if not using any other method. But especially useful as ‘backup’ for days when I use a mooncup. Also very comfortable.

Not right for me in summer

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Personally didn't get on with these for summertime periods but would consider getting out again in winter. Thick lining is too sweaty and not odour wicking. Fabric takes a while to dry and not that comfy to wear. Winter periods may be a better time as feel more like thermals. Everyone is different.

Best ever period pants.

Yes, I recommend this

Very comfortable, lovely cotton feel. I can't abide polyester or plastic underwear. Size 10 is actually true to size, amazed! Fits without bunching or having to adjust them in any way. Rinses out really well under the tap.

Stylish and does the job!

Definitely fit for the purpose of a period. I hadn't realised I'd bought the bikini fit so I didn't like the fit but that's my fault. I would say, anyone ordering whi has had a c section should avoid as the fit cuts right across scar line. You can feel the lining across the bum which sometimes felt like they were falling down but weren't. Didn't bother me after the first few days though. Happy enough to go and buy the full fit knickers.
