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

Disappointed

No, I don't recommend this

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

Comfortable

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

No, I don't recommend this

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.

Very large

I bought these to absorb sweat at the gym. On receipt they seemed large but of course you can't really find out until you try them on and then its too late to return. They are actually labelled as sleep shorts which explains why they are so loose. No complaints on absorbency as I am not using them as period shorts but they are uncomfortably baggy so consider sizing down.

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
