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 Boxers - 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

Runderwear Men's Merino Running Boxers - Temperature Control

Odour-Resistant

This intelligent, organic fibre also absorbs both odour-causing bacteria and moisture from your body, quickly. It traps the bacteria to make it odour-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 Men's Merino Running Boxers - 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 Men's Merino Running Boxers - Super-Fine, Ultra-Soft
 
Runderwear Men’s Merino Running Boxers are designed to deliver unrivalled comfort and performance, with a 6-inch inseam and silicone leg grippers to hold them in place during movement. All the features of our classic Men's Running Boxers - 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 odour-causing bacteria and moisture from your body, quickly. It traps the bacteria to make it odour-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

Snug and comfortable

I've been using these during late autumn / early winter, and have found them very comfortable. They're not particularly heavy, so I imagine they'll be comfortable all year, but a little thicker might have been better for the coldest months. I find that these boxers ride up a little at the hem line (I'd guess about an inch), but they never move into or cause any discomfort in the crotch area, and stay perfectly in place at the waist. Size-wise, I suggest sizing up if you're at or near to the size boundaries - I have a 32" waist, and the M is just about as tight as would be comfortable.

Thank you for your review this is greatly appreciated, We hope that you have many more happy miles in your Runderwear Boxers and thank you for your purchases!

Second pair for the winter

This is the second pair I’ve bought in quick succession for my winter runs. My mother in law doesn’t know it yet, but she’s giving them to me for Christmas! Great running undies. I’ve run out in these in the cold and the rain, and was extremely comfortable. No chafing. No cold thighs (or anywhere immediately anywhere north of there!).

Thank you for your feedback, We are pleased to hear that you are loving your Merino Underwear and they have been comfortable whilst keeping the chafing away! We love to hear this.

Thank you for your purchase with Runderwear!

Great exercise boxer shorts

Great purchase. Very comfortable, wicking away sweat well during exercise and temperature control was great in warm and cold temperatures. Leg grippers worked well too.

Thank you for your feedback, Great to hear that you are loving the Merino Boxers and the leg grippers to keep them in place!

Thank you for your purchase with Runderwear!

Unbelievable Comfort

I was at first a bit dubious about the price of the Merino boxers
but oh my they are worth every penny they are so comfortable,
you just feel like you are wearing nothing at all.
I have tried them out on lots of long Runs and I rate them very highly
and would definetley recommend them to anyone. 10 out of 10 for me.

Thankyou for your feedback, Great to hear that you are loving your Merino Boxers and you find these to be comfortable and worth the money.

Great to hear that you would highly recommend, We love to hear this!
