    Horrible! Ive bought Knix regular panties fir years including the boy shorts. Thought I’d try the cotton ones. The fit was big & the leg openings rolled & stretched. Worse, they were not leakproof. I will never buy these again & tell other women to avoid them as well. A complete waste of money.

    Comfy and fits well

    These fit me very nice and don’t ride up on me. I wear more for sweat and urine absorption due to urinary incontinence and they works great. I am dry and no more pads! Easy to care for as well.

    Moving away from pads

    After a long time wearing pads it's really nice to not be reliant on single use items anymore

    Comfortable and Secure

    Love these leakproof cotton underwear. They are comfortable against my sensitive skin. I wear one size larger than I need to prevent skin irritation. They work well, I no longer have to worry about leaks. I appreciate that they are machine wash and dry.
