    Really not suitable for all body types/shapes

    The underwear is shaped for curvy bottoms and smaller waists. On me, there were large gaping spaces around my bottom where the underwear should have been against my skin. If put to the test, they certainly would not have been 'leakproof'. A reduction in size would not have changed the outcome as they are just the wrong shape for my body type; the waist size was correct for me but the corresponding bottom size was much too large.

    Unfortunately, the Boody returns policy does not include underwear and the 'comfort guarantee' specifically excludes sizing issues. It was a dud online purchase for me and an expensive pair of undies are now headed for landfil.

    What I did like about these undies is that the absorbent gusset was full length from the top front to the top back. I couldn't see this feature mentioned online... but it is written on the box the undies come in. Bear in mind, this does make them quite heavy though and I wondered how this might feel (or if the undies would sag) when full.

    Great fit

    Slightly more absorbent area than the day time full brief. No leaks, very comfy, great fit 10/10!

    A good night’s sleep and clean sheets

    I’ve worn regular, non-period Boody underwear for a few years now and was pleasantly surprised to see that they now sell period underwear. I was looking for a good pair of overnight period underwear and decided to try these. My first impression was that I loved how soft they were, and that the period coverage was extensively impressive. The “absorbent” section goes all the way up the front and the back. In other period underwear, I often had to change in the middle of the night cause it was never enough coverage or I leaked through. Not so with this pair. They lasted all night (9 hours) with no leaks, and I still felt dry in the morning. No sticky or wet feeling. I felt like I could have gone another few hours in them.

    They are very thick and heavy and would be bulky under clothing, but I don’t anticipate wearing these out in public. I air dry them and they do take a long time to dry - at least a full day. I’ll be buying a second pair, and also trying out the other absorbencies in their period underwear selection. Definitely recommend these.
