    Comfortable but leaks

    These are comfortable enough for a leak proof underwear. The bulk takes getting used to if you get one for high absorbency. I seem to leak out the sides though, day or night, even after I sized down. Don't be fooled by how tight they feel when you try them on at first!!! The underwear stretched almost a whole size for me, so size down when purchasing.

    So Comfy!

    I love my Knix light leakproof! I wear it everyday just to stay fresh and dry and in case of unexpected leaks.
