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.

Could be better

No, I don't recommend this

Ok. The gusset is the same size as standard knickers so doesn't provide with good coverage needed to deal with a heavy flow- let alone a super heavy flow. I got these to sleep in and they did not do the job at all. For day use they would be ok. The coverage front to back is good.

Badly designed

No, I don't recommend this

These are very poor. The absorbent panel is a narrow strip down the middle with non absorbent material down the sides. It is a totally ineffectual product. I was disappointed as the idea is really good - unfortunately the execution is poor. I would not recommend these.

Great quality

Yes, I recommend this

Lovely quality, fit great absorbency, my daughter has different styles for the start middle and end and feels confident wearing them never let her down they wash really well and keep there shape, although initially they seem expensive in the long run saves so much money and waste and do last basically until they wear out I would highly recommend them.

Very comfortable and do their job. Only reason I gave 4 stars is the legs roll up under leggings and trousers.

Poor Quality

No, I don't recommend this

Sadly these seem very poor quality compared to others available from M&S. They are not reliable and the material has puckered around the top after only 1 wash

Disappointed

No, I don't recommend this

The product was listed as super absorbency but they didn’t hold the smallest of leaks, very dissapointing. The fit was also poor, far too large overall but low rise in the back.
