Confidence not just for periods!

Yes, I recommend this

I bought these for sleeping in for bladder issues: occasionally I wouldn’t make it to the toilet in time and I’d need to change my pjs in the middle of the night. These pants are giving me confidence and comfort and my skin is happier always being dry.

Thinking of cutting the legs off

I've been using the m&s heavy absorbency knickers which do the job but sometimes peak at the front. These look great and the pad does stretch a bit more front and back but I was finding the fabric between the groin also takes on fluid so I couldn't wear for long. Salt make a better super heavy period knickers without the long legs. I should have gone for more of those

Pants that work as they should

Yes, I recommend this

These are not for looking sexy but are perfect for those of us who have occasional leaks or unexpected urgency. They genuinely absorb a lot giving back dignity. I have lots of pairs. For me they aren’t forpperiods just for urine leakage and they do their job.

Brilliant knicker shorts.

These knicker shorts were excellent quality but came up a bit big for me, so had to return for smaller size. Highly recommend

Comfortable but not for ‘super heavy’

No, I don't recommend this

Comfortable and good quality but still leaked through after a couple of hours when on my heaviest days. I think this is more down to the design rather than the absorbency. The padding could be a bit wider. The ‘heavy’ absorbency underwear were better.

Such a revelation

Yes, I recommend this

First time using period pants and I’m very impressed. I bought these for night time which causes me the most issues and they are a revelation! No more leaks and they are very comfortable and discreet too.

Not keen

No, I don't recommend this

I found these needed to be slightly higher at the back and needed some elastane in them as they are too loose. I did not find them comfortable at all.

Great for Stoma/Ileostomy

Yes, I recommend this

I tried M&S stoma pants and they didn’t come up high enough for me. I found these period pants suited my need much more. I have an ileostomy bag, which I can tuck in the pants, knowing if it should leak , I feel secure. I recommend for women and men. I would like the waist even higher if possible.
