    I am 5’4” 189 lbs dense bones. Size 14/16 womens. Purchased L. After wearing all day by hour 3, I was not a fan of the waist band and rise on me. Uncomfortable elastic bad. Main Material was great. By hour 4 lots of bunching and give to the material especially in the rear and crotch.

    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.

    LOVE THESE BRIEFS!!!

    This is my 2nd pair of Leakproof Logo Modal Rib Boxer Briefs. They are so very comfortable!!! I like them much better than my regular underwear. I'm on the look-out for other colors so I can buy even more! HIGHLY RECOMMEND!!!

    uncomfortable back seams

    These briefs seem to do the job, but I can feel the seams in the back when wearing them. Not comfortable as underwear should be.
