Feedback
"100% Leak proof! I felt myself go a little on double unders, but for the first time ever I didn't feel as if I had to stop and break sets!"
“I felt so confident doing my workout today. It was so good! There is no better feeling as a woman, who has had children and can now keep up with the young ones!”
"What a win! Had amazing coverage. They didn’t feel bulky like my period thongs. Great product! I’ll be wearing them all the time, especially as I’m 3 months postpartum."
“I’m OBSESSED with Double Undies! I am doing a load of washing every day just to be able to wear these to the gym!"
"Today I struggled with pelvic floor control. There was no wetness on my tights or the underwear itself, the absorbent layer caught everything!
"Honestly, I don’t think I can WOD without them. Box jumps, DU’s, squats. Bring it on!”
"40 x 4 rounds of DU's unbroken. Absolute GAME CHANGER!"
"I couldn't feel that I was wearing them, and still felt fully protected during the workout!"
Wow!!! Just finished a heavy session. These are strongman / woman approved! Game changer for me. Love how comfortable my behind felt too as I tend to get uncomfortable with regular thongs. Highly recommend!!
