my only complaint is that i have thick thighs and the slip was a little short to come up to my hips properly despite my measurements being in range - so if you're on the upper end and have thick thighs, i would recommend going for the medium. shipping also took a while but i'm willing to pin that on general postage delays atm.
the slip is super comfortable, and very absorbent. the team sent me a free sample of the next size up and it's even more comfy. slim, practically invisble, and comes up high enough to contain faeces.
i can also change myself now that i've got the hang of it.
