LB Women understand These are better than the Kirkland (Costco) brand under garments. They FIT BETTER, don't leak, and reduce smell and absorb quickly. Which is more then I can say about the other brand who claims, right on there bags/box 3+ Benefits 1. Dryness Protection + 2. Odour Protction 3.Breathability. Now that I read this it does not say anything about the fit. I quest that doesn't matter, it's only about your embarrassment, your laundry load, if you can still do your own laundry or hard on your bank accounts. I will never again buy kirckland adult "under garments"
