Seamless & Sustainable

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

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

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?

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!

Very comfortable and good fit. Good for all sports or even just everyday wear.
So far wash and dry well. Maybe a little bit expensive but it is merino. Is there a matching running bra/crop top?

smooth fit

I am a big fan of merino wool especially for exercise. I do have other makes of merino pants but not specifically for running. I would have preferred if they came up slightly higher as I am long between waist and crutch and don't like pants that don't come up high enough but that is just me - they are probably high enough for most. I would have preferred a higher merino wool content but generally they are nice and are comfortable. Would be nice if they were available in colours.

Very comfortable, no chafing and sit nicely on waist. Prompt delivery. Prefer these merino ones to the other style
