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 Men's Merino Running Briefs - Seamless & Sustainable

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

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

Only 45% merino!

I just received these "merino" wool underwear, thinking they would be merino wool. They fit fine, and I have yet to see how they perform with sweat and odor, but can they really credibly claim merino wool? They're 45% merino wool and 40% polyester, which I only discovered when looking at the actual garment. The website touts the benefits of merino wool as if the product is primarily merino. Coming back to the site, I can't seem to find the merino content listed anywhere. Perhaps, these should be advertised as polyester underwear, and they should have a full spread articulating the wonderful merits of polyester? Don't buy these if you're expecting to get a garment that is primarily merino wool.

Hey Teddy,

Thanks for your review, Our co-founder Jamie who is a marathon runner wanted to develop a pair of seamless merino underwear for his own running. Through years of development the selected yarn was a blend of merino and Thermocool which is a thermoregulation polyester (not regular polyester) keeping you cool when hot but also warm when running in colder environments. The yarn is a premium yarn from Südwolle.

I am looking forward to hearing your feedback after you have trialled and we of course take on board your comments and we must communicate the above clearer on our website. I really appreciate the feedback and look forward to yours.

Best,

Molly

Excellent Briefs

I bought these a while ago,but hadn't done a review until I wore them to give my honest opinion.....
I can honestly say I was totally suprised how good they really are. I put them on for a 13 mile hike ,which was a very hard trek ,with steep hills..weather was very warm ,17c and sunny..I wore these for over 6 hours and never felt hot wearing them,and I felt like I had gone commando they were so brilliant..
No sweating in the private parts or creases of the legs nor was my waistband wet/damp from body heat..
Definitely 💯 recommend, really good value for money and hold everything in place too if you get me..
Would love too see them in black or khaki in the future for bit more choice..
Treat yourself, you won't regret it....

not great

bought a pair of these and a pair of the standard non-chafe briefs. The non-chafe are far superior and comfortable. The merino are sadly unusable for me
