seamless

Sometimes less is more – and for runderwear, less seams = more comfort. No side seams, no labels and most importantly, no rubbing. There’s less wastage, too – so choose seamless to run smooth and free.

breathable

The little things often make the biggest difference… Micro-perforations allow our underwear to breathe all year-round and improve airflow – which means you won’t overheat. Be cool, stay comfortable.

Very comfortable

They come up quite high so can show above leggings depending on design. Nonetheless, they are very comfortable and stay in place. I've had problems with knickers falling down during aerobic exercise, which was the reason for purchasing these, but they stayed put through a full class. Very happy.

Hey Louise,

Thanks for your feedback, Great to hear that you are loving your Runderwear Thong and they stayed in place during your Aerobic class. We love to hear this.

first time the wife hasn't complained about wearing a thong!

she really likes them, and finds them comfy for running longer distances, which she was concerned about.

Perfect Running Underwear

As a regular customer I took advantage of an end of line offer. These G-strings are perfect for wearing under shorts or leggings. They’re so light you’d hardly notice that you’re wearing them! Soft comfortable fabric with a snug but not tight fit. They keep their elasticity and softness after many gentle washes. The end of line garments had a slightly wider back string compared with the latest ones but they’re still a comfortable fit. Sold as ‘Women’s G-Strings’ but these should be ‘unisex’. Runderwear are definitely the leaders in running undergarments. I’ve not found an alternative manufacturer that makes such a good runners g-string.

Hey Bob,

Thanks for your feedback this is greatly appreciated. We are pleased to hear that you are loving your Runderwear Underwear and they have been perfect under your leggings and Shorts. I have passed your feedback onto the team as this is appreciated and always taken on board. Thank you for your purchases with Runderwear.

Really comfortable and soft material

Love the runderwear thong, so soft and comfortable to wear, and having been on a 20 mile run wearing them, I was pleased to have zero rubbing anywhere. Washes really well, so I will be purchasing more! I'm a size 10-12 and the medium fits perfectly.

Hey Karen,

Thanks for your feedback, Great to hear that you are loving your Runderwear Thong and love how comfortable they feel on. Happy Running!
