Leakproof Thong

I now feel protected lifting heavy and can wear any color! Leakage is part of every day life for women thank you for creating this product!!!! 🫶🏻🫶🏻

I got these for the gym and they are now my everyday underwear. I have erratic periods and this way I feel protected everyday. Now patiently awaiting nude colour so I am sorted for every outfit.

After one wear I'm sold! Best undies for training and general mum life chasing small people around. I need to buy more!

I’m early into my powerlifting journey and preparing for what will likely come as I progress with heavy deads! Wearing these for the first time this week though, what I love about them is they do not move!!! No rolling downwards, no readjusting. They just stay put. Amazing! I’ll be wearing nothing else in future.

Finally a g string that can support my frustrating leaks when sprinting! Others haven’t held up and double undies are my saviour. Thank you so much xxx

Sad I only have one pair, need to order more asap! Will let all my members know about how good these are too 🙌

Wife loves them. Feel and support is what she like most about her thong.

The best period/leakproof undies in the game!
I've tried a few different brands, and these ones are the best by far - comfortable, practically invisible under tights, and very absorbent.
I also love the little waterproof bag that comes with them, so you can change them when needed (ie: in the middle of a comp) and know they're hygienically tucked away until you can get them into the wash. I've got so much more confidence when doing double unders or heavy OH lifts.
Yes, they're a little more expensive than other brands, but they are more than worth the extra $.

I have been wearing liners everyday for the last 15 years as I have always suffered from having weak pelvic floor muscles. I am only 28 and haven’t had kids yet so I have always been worried. What’s to come after that. I met with the beautiful ladies from Double undies at the fitness expo and introduce me to their incredible product which I have now tried for the first time and is an absolute game changer time to throw out those liners and not look back! I have seen ads online with a similar concept but the features that double undies offers in their product is unmatched. It’s definitely worth the buy. The quality is insane and the comfort throughout the day was a great experience.

Does their job well, comfy and great for protecting against leaks and absorbing sweat during workouts. Generous sizing next time I will get a size down.
