Very comfy but too small where you need it

Originally posted on marksandspencer.com (UK)

These fit really well and are very comfortable. The gusset goes all the way from the front to the back which is really helpful. The only thing is the middle part of the gusset is too small. It goes wide at the back but the part where you need the most protection is too thin/narrow! I did leak out the side.

Comfy, no leaks, but not for very heavy nights.

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Extremely comfortable to wear overnight, and having this in a shorts design definitely helps with the worries over leaking. I don't think these would be good enough for a heavy night (day 2 or 3) but perfect for the rest of the days. Some people have commented that they're a little loose, but I think any tighter would be uncomfortable overnight.

Good but not heavy absorbency

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

The period knickers are decent for medium to low flows and feel secure for around 5-6 hours. Any longer and with a heavier flow, the knickers are not secure and leak.

Brought the largest size, which are a good fit for my size 22 apple shape. Using for small leaks and they work well. I’ve washed and dried them and they came out fine. Overall good value for price

Short style pants

Yes, I recommend this

I am uncertain if they will prove to be as effective as your standard pants because of the shape of my thighs. Pants with legs tend to ride up which is uncomfortable. Time will tell I hope

The shorts did not suit me as they leaked at the sides. Rather disappointing as other styles have suited me well.

Comfortable

Originally posted on marksandspencer.com (UK)

Don’t really like the shape (personal choice) of these but they are quite comfortable and i have decided to keep as i think they are probably more absorbant than others

Give these a miss

Originally posted on marksandspencer.com (UK)

I’d give these a miss. Material isn’t the best and they are a baggy fit. I wan these to be tight and secure if bed but the material means they certainly aren’t that. I’d avoid.
