I have been using the modibodi sensual underwear range in a bulk pack for my period cycles for at least a year successfully without any leaks and with complete satisfaction with the product. I work as a nanny so I take the children in my care to the pool most weeks and I found that I really didn't like the hassle of going swimming when I'm on my period. I have a cup that I can use, but when I'm looking after other people's children, it's a hassle to put it in and take it out as they come to the toilet with me! And I like easy and I like my bits a little more private. So, I'd been dreaming of getting these togs to make this way way easier for me and with the hope that it would give me peace of mind every time I swam. They're perfect. The design I love. When they arrived, I put them on straight away and lay about my house just in my togs for the day. Comfy, I love the straps, I'm usually a size 14 - 16 but I chose 16 as it was in stock and because I don't want too tight togs, but they are loose enough if anything on me. I've used them at the pool once for an hour on my heaviest day (second day) with no leaks and full confidence, and that my friends is a wrap! Thanks for the peace that I feel knowing my body can release my cycle with ease and be captured by the underwear and togs that I use. It has changed my entire life, I would never go back and should I have girls of my own in the future, I am so glad I can provide them with this kind of period support.
