I have extremely sensitive skin and long periods, which can get very heavy. With other pads there's too much friction and I feel like I'm wearing a diaper stuffed with hay by day 3, it is miserable, and a huge problem in my life! I'm on Depo for my BC so my period has no schedule, I'll have it for 10 days, be off for 4, be on it again for 2 weeks, off for a week, on for a week, etc. Trying to find the right pad has been a nightmare and a half. Thank GOD for the Always Infinity Flex Foam pads! It absorbs very well, but wicks the fluid away from your body to the base of the pad, so you don't feel like you have a soggy Stewie diaper on. It doesn't leak through, even with extremely heavy flow using a regular pad with wings. What I love most though is that there is absolutely NO irritation, no friction, it's like I'm wearing high quality cotton underwear. That is what I am the most thankful for. No more chafing, redness, swelling, Irritation or discomfort of any kind. Honestly, if you haven't tried these yet, do it! I am a busy autism mother of 2, I am a stylist, Educator and Researcher, I really have zero free time. I love these things enough to take time out of my day to write this review - that's saying something! Lol. Please, never stop making these! If you do please let us know a few months ahead of time so I can stockpile them.
