    Very thin and ride up

    These are sooo thin, and they ride up. Definitely not worth the money in my opinion.

    They are soft though and I’m sure would be okay just for sleeping in. But the riding up is very annoying.. you can’t walk without it rolling up

    La protection ne monte pas assez haut en avant. J’ai moins aimé la coupe mais cela est parfait pour une soirée où on porte des vêtement court, moulant ou ajusté.

    SOOOO COMFY

    Light/ end of flow days.

    Love walking around in these in just a hoodie at home or sleeping in them. They make my bum look great!

    Not leak proof

    These leaked the first night I used them. The gusset didn’t stay centred when I was sleeping on my side.

    Not leakproof

    It's funny how I got an email asking if I wanted to write a review of this product on the morning when I woke up completely leaked. I don't think anyone wants to see it, but I took a picture of my Leakproof Logo Modal Rib Boxer Brief with blood all over the crotch. Definitely won't buy it again.

    Also, I never wore them during the day to go out, as they're bulky.
