What our customers are saying
Customers say these shorts are exceptionally comfortable and feel like regular underwear, with many praising their soft texture and perfect compression. Users appreciate the worry-free sleep and confidence they provide during periods. Many reviews mention the shorts work well for gym workouts and daily wear. However, some customers experience leakage issues, particularly side leakage and concerns about gusset width and positioning. Common feedback includes requests for lighter absorbency options and more color choices. While most find them true to size, some recommend sizing up for thicker thighs. Several users note durability concerns with seams separating after extended wear.

    My late term pregnancy life saver!

    These undies have saved my butt both literally and figuratively! When I hit 6 months pregnant I couldn’t leave the house without a stash of pads (yes that was learned the hard way) but now I can throw my Knix on in the morning and be good all day. Highly recommend for anyone expecting.

    Very comfortable.

    These are really comfortable but I wish they also came in just leakproof for moderate leaks. I really don’t need the super leakproof and would like another option. They do fit nice though.

    So far so good

    They fit PERFECTLY and are incredibly comfortable. The absorbent lining isn't the shape I was anticipating, but I have not had any problems so far.
