COTTON IS ROTTEN

54% MERINO WOOL // 42% NYLON // 4% SPANDEX // PROUDLY 0% COTTON

It’s not just the materials, it’s the construction.

  • We reinforced the high-wear areas in the toes and heels with extra NYLON to reduce friction and add toughness.
  • The sock body is optimized with more MERINO to breathe better so your feet stay dry longer.

MERINO WOOL

Merino wool is durable, soft on the skin and won’t itch like traditional wool.

Merino wool is breathable and regulates body temperature, even when wet.

NYLON

Nylon is one of the strongest, most durable synthetic fibers available. There’s a reason our rucksacks are built out of CORDURA®.

We use fine nylon fiber with excellent abrasion resistance, which also helps to reduce friction and prevent blisters.

Spandex

Spandex aka elastane is the industry standard for stretch and durable elasticity.

The right ratio of spandex maintains the shape and fit for the life of the sock without compromising durability.

PADDING WHERE YOU ACTUALLY NEED IT

We got sick of wearing out other socks so we added more padding along the heel and ball of the foot. The heel padding is extended up to the achilles to actually give you cushion where you need it when wearing boots like MACV-1.

FITS RIGHT, EVEN AFTER ALL THE MILES AND ALL THE DAYS

Extended arch support and a natural fit through the ankle and calf makes for a comfortable sock that’s not too tight and doesn’t slip over time and distance. These socks maintain their shape wear after wear.

WEAR OFTEN, WASH SPARINGLY

Merino wool naturally resists bacteria and fights stink. Wear as often as you want without having to wash ‘em after each use. Saving you both water, and time.
