How to Wash Heated Socks and Gloves (and Store the Batteries)

Always remove the batteries before cleaning any heated garment. Heat Up Merino Wool+ and Junior heated socks can be machine washed on a delicate cycle or washed by hand; heated gloves, mittens, vests and bermuda shorts should be cleaned by hand and left to air dry, unless the care label says otherwise.

Here is how to keep your heated gear working season after season.

Before any cleaning

• Switch the heat off and unplug the battery or power bank.
• Take the battery out of its pocket and set it aside, away from water.
• Check the care label and the user guide that came in the box. They are specific to your model.

Heated socks

The Merino Wool+ and Junior heated socks are made to be washed. With the batteries removed:

• Machine wash on the delicate cycle, or wash by hand.
• Use a mild detergent and skip the bleach.
• Turn them inside out to protect the outer knit.
• Air dry, flat or hanging. Never put heated socks in the dryer or on a radiator.
• Wait until the socks and the battery pocket are completely dry before reconnecting a battery.

The merino wool blend resists odours, so a quick airing between uses is often enough. Washing less often also helps the socks last longer.

Heated gloves and mittens

We do not recommend putting heated gloves or mittens in the washing machine. Instead:

• Wipe the outside with a damp cloth and a little mild soap.
• Rinse the cloth and wipe again to remove the soap.
• Let them dry at room temperature, fingers up and cuff open, so moisture can escape.
• Keep them away from direct heat: no radiator, wood stove or hair dryer. Strong heat can harden the leather palm and damage the membrane.

After a wet day, do the same: take the batteries out, open the cuffs and let the gloves dry overnight at room temperature. The breathable Hipora® membrane in the Mountain and Peak gloves helps moisture escape.

Heated vests and bermuda shorts

Remove the power bank from its pocket and unplug the cable. Follow the care label: in most cases, spot clean the shell with a damp cloth and mild soap, then hang to dry at room temperature. Do not tumble dry and do not iron over the heating zones.

Storing your gear and batteries for the summer

• Clean and dry everything completely before putting it away.
• Store batteries partly charged, around half, rather than full or empty.
• Keep them in a cool, dry place, not in a hot car, an attic or in direct sunlight.
• Store batteries outside the garment, in their pouch, with the connectors protected.
• Top up the charge every few months, and charge fully before the first cold day.
