The size is accurate, the fabric feels very pleasant against the skin and the briefs are well-made.

These are comfortable, the liner isn't overly thick like a pad, easy to clean, soft material. They do roll up my leg though. The liner i think should go further back, not further forward? Shame is wasn't covered in the Fashion/underwear section of offers though.

Could be better

On the plus they are comfortable and the size is spot on. The padding isn’t bulky which is helpful BUT on the downside they aren’t very absorbent and defeats the object. Probably best to use on lighter days but not suitable for heavy days. If

Good quality product, ideally I would like to see the absorbance pad go up all the way on both sides. Soft and true to size.

The name suggests these are for children but they’re for anyone. No spillage, extra comfort and without feeling too hot.

Great for overnight confidence and quick washing

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I bought these for my daughter who is really pleased with them. The "pad" part reaches all the way from the waistband front to back which gives her great protection and confidence over night. The actual knicker part is a nice light material which she says makes her feel like she has nothing on and they dry really quickly on the line.

These are super comfortable, although I have to agree this is medium flow and not heavy flow. Heavy flow ones should have thicker absorption, and protection all the way up the back for sleeping in for e.g.

Not for me

Not for me. Bought these after reading some reviews about using them for slight leaks. Found that when they were even slightly moist they were uncomfortable to wear.

Didn’t love it

Originally posted on marksandspencer.com (UK)

I wanted to try these shorts as they are not my usual style for heavier period days thinking they were very fitted but the material wasn’t thick enough and the shirts sat lower than I like. May just be my style versus the shorts not being good.
