Description

XTM Performance Heater is a thick winter sock in an Australian merino wool blend: 40% Australian merino, 40% acrylic, 15% polyester and 5% elastane. It has a tall 37.5 cm leg, an average weight of 104 g, a regular fit, and comes in three adult unisex sizes and seven colours.

Who it's for

Anyone whose feet feel the cold first. The Heater is a sock for the snow: a bluebird day at Perisher, a week of lift queues at Falls Creek, or a winter camp at Dead Horse Gap where the ground is frozen by dinner. The tall leg reaches well up the calf, so it sits above the cuff of a ski or snowboard boot rather than bunching inside it.

It earns its place on cold nights too. Pull on a fresh pair at camp or at home when the frost is on the lawn, and your feet stay warm right through until morning.

Fit and layering

Regular fit, shaped to follow the foot and leg with ease for movement. The elastane gives the knit its stretch and recovery, so the sock stays up without a tight band.

  • A2-8: US 2 to 8, Euro 36 to 39, foot length 23 to 25 cm
  • A6-10: US 6 to 10, Euro 40 to 44, foot length 26 to 28 cm
  • A11-14: US 11 to 14, Euro 45 to 48, foot length 29 to 31 cm
  • 37.5 cm leg length

The A2-8 and A6-10 sizes overlap at US 6 to 8. If you sit in the overlap, measure your foot and go by the foot length.

Fabric and construction

The yarn is 40% Australian merino for warmth and softness next to skin, blended with acrylic and polyester for durability and elastane for stretch. The result is a thick, soft sock you can wear from first chair to après. The Heater is a certified carbon neutral product.

Colours

Seven colours: Black, Grey, Ocean, Kalamata, Lava, Dusty Pink and Fog, each with the Heater name knitted down the leg. Black, Grey, Kalamata, Lava and Ocean come in all three sizes; Dusty Pink and Fog come in A2-8 and A6-10.

Care

Turn the socks inside out and machine wash cold on a gentle or wool cycle with wool detergent. No fabric softener or bleach. Line dry or tumble dry on cool, and never iron or dry clean them.
