Seamless & Sustainable

The world’s first seamless Merino running underwear range. The magic of Merino wool with the added bonus of 360° seamless construction provides unrivalled comfort and performance. Our Merino wool is responsibly sourced from non-mulesed sheep that are sheared once a year, offering a sustainable and renewable fibre

Runderwear Women's Merino Running Briefs - Seamless & Sustanable

Temperature Control

Merino wool comes from Merino sheep, who face scorching hot summers and bitterly cold winters in their natural Australian mountain habitat. As a result, their wool has evolved to have unmatched levels of temperature control - so our Merino range will keep you at the perfect temperature in any conditions

Runderwear Women's Merino Running Briefs - Temperature Control

Odor-Resistant

This intelligent, organic fibre also absorbs both odor-causing bacteria and moisture from your body, quickly. It traps the bacteria to make it odor-resistant and it can absorb up to 35% of its own weight before feeling wet, meaning you stay fresh and dry on your run

Love these Merino briefs

I work many hours outdoors in the winter and decided to give these merino briefs a chance whilst we were experiencing sub zero temperatures recently, especialy as they were half price in the sale. I'm usually a size 10/12 in briefs but there were only size Small left in this style (which I prefer to the hipsters), so I decided to take a punt on a opair. They fit perfectly, they're comfortable (delighted with this as I'm allergic to many woollen fabrics) and really give an extra layer of insulation! I immediately ordered three more sets before the small size also ran out of stock in the sale.

I'm a vegetarian and I do worry about the cruelty of some sheep shearing so I was pleased to read these are ethically sourced.

Hey Joanna,

Thank you for your lovely feedback this is greatly appreciated. We are pleased to hear that you are loving your Merino Briefs and they have been perfect for sub Zero Temperatures. The Merino is our Premium fabric and will keep you at the perfect temperature.

Happy Running!

Very disappointed

I have to say I’m very disappointed by these pants. I had high expectations but they go straight up my bum as soon as I start running which makes them very uncomfortable

Great running briefs

Very comfortable and fit well. Nice that they contain a sustainable fabric. Only downside, sanitary towels etc don't stick very well.

Hey Carolyn,

Thanks for your feedback, We are pleased to hear that you are loving your Runderwear Briefs and love how they fit. I will be sure to pass your feedback on to the team and this is appreciated.

Good quality but order one size up

These merino wool briefs are a bit small -- I ordered one size up and the large fits the way a medium normally does. I find the high waist is too high for me, so I'll order the hipsters next time. other than that, they're very comfortable.There isn't as much coverage in the back as I expected but they stay put, so no complaints there. I wear these as my everyday underwear, not just for running.

Hey Jean,

Thank you for your feedback, The Briefs go up to around the Belly Button where the Hipsters will be less coverage on the back and will sit on the hips. Great to hear that you are loving the quality of the Merino Briefs and have now found the perfect fit.

Happy Running!

Runderwear Women’s Merino Running Briefs are designed to deliver unrivalled comfort and performance. All the features of our classic Women's Running Briefs - seamless design, breathable, moisture-wicking and of course, chafe-free - enhanced by the magic of Merino; the world's best natural performance fibre

HOW DOES IT WORK?

Merino wool comes from Merino sheep, who face scorching hot summers and bitterly cold winters in their natural Australian mountain habitat. As a result, their wool has evolved to have unmatched levels of temperature control - so our Merino range will keep you at the perfect temperature in any conditions

This intelligent, organic fibre also absorbs both odor-causing bacteria and moisture from your body, quickly. It traps the bacteria to make it odor-resistant and it can absorb up to 35% of its own weight before feeling wet, meaning you stay fresh and dry on your run

To prevent overheating the sheep are sheared once a year, so the fibre is sustainable and renewable. The fineness and softness of Merino is measured in Microns – at 18.5 Microns, Runderwear Merino is super-fine – making it ultra-soft and non-itchy against your skin
