Seamless & Sustainable

Our Merino wool is responsibly sourced from non-mulesed sheep that are sheared once a year, offering a sustainable and renewable fibre

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

Runderwear Women's Merino Running Briefs - Odour-Resistant

Super-Fine, Ultra-Soft

Merino wool is 3 times finer than human hair. The fineness and softness of Merino is measured in Microns – and at 18.5 Microns Runderwear Merino is super-fine. That results in an ultra-soft and non-itchy feel against your skin, so it’s the perfect first layer for all of your year-round running adventures

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.

Size up small so I don't think they will be comfortable - disappointing

Very impressed

I purchased the merino underwear for a trekking holiday as per equipment recommendations. I thought I best try before the big event. I am very impressed! They are extremely comfortable, I was worried they may be a little itchy but absolutely soft on the skin. Managed a hill hike of 10 miles so far and they remained comfortable throughout. Wash up well too as per washing instructions. Highly recommend. I just hope for the price they last a long time!

Good fit but prefer the regular fabric

Good fit & comfortable but not as soft as I expected given they contain merino, I prefer the regular fabric which seems softer and the items are less expensive. Not keen on the grey colour, would prefer black or even better, a choice of colours.

Thank you for your feedback, Great to hear that you like the fit of your Merino Briefs and find these to be comfortable! Our Merino range is our premium range as this wool comes from Merino sheep, who face scorching hot summers and bitterly cold winters in their natural Australian mountain habitat. I will pass your feedback onto the product team and this is appreciated! Happy Running,

Good fit but....

....... doesn't seem to allow a sanitary pad to stick to the material? I haven't read any other reviews with the same comment, but my pad simply would not stick at all, which means I can't wear these knickers for a week each month.

Thank you for your feedback, I am sorry to hear this and will pass your feedback onto the product team. We are pleased to hear that you have found a good fit in your underwear!
