We love our thermal wear—it keeps us cozy and warm through every cold season, whether you're enjoying a brisk fall hike or braving the chilliest winter nights. To anyone who’s ever experienced the magic of a really good pair of thermal socks or the perfect thermal base layer, you know: once you find them, you want to keep them for as long as possible.
But how do you make sure that your favorite thermal wear stays soft, functional, and ready for action season after season? The secret lies in a little tender loving care. This is your go-to guide on how to take care of thermal clothes so they’ll stay with you for many winters to come.
Washing Thermal Clothes: The Dos and Don’ts
Let’s start with the basics—how to clean thermal clothes without sacrificing their cozy warmth. Washing thermal clothes is easier than you think. These simple tips and tricks will help keep your thermals clean without wearing them down, so you get the most out of them.
Warm Water, Yes! Bleach, No
Always check the manufacturer’s tag before washing your thermal clothes.
Most thermals can be machine washed in warm water (40° Celsius; 104° Fahrenheit). Just throw them in the machine with detergent – no bleach or hot water. Bleach can break down the fibers that make your thermals soft and warm! Hot water? It may feel amazing in a hot bath, but it’s not as kind to your thermals. Stick to warm water instead—your thermals will thank you.
Happily, you don’t have to go to the bother of dry cleaning these items, either. The best care for your thermals is the simplest care.
Remember to wash dark colors separately and don't worry about turning them inside out. It's better if you just throw the garment in the washer as is.
How Often Should Thermals Be Washed?
To wash or not to wash—that is the question. But when it comes to thermal maintenance, the answer depends on the type of thermal wear.
Thermal Base Layers
For base layers, aim to wash them after three to five wearings to save yourself a little water usage (and great for the environment, too!).
Thermal Socks
Socks, on the other hand, are a little less forgiving. They should be washed after each wearing. Let’s face it, socks go through a lot—feet are just naturally sweaty and a fresh pair feels much better the next day.
Accessories & Other Apparel
For items like hats and gloves, you can wait a lot longer. A wash once a season or as they get visibly soiled is sufficient. Similarly, thermal outerwear or jackets can be washed once or twice a season. Unless you’re on a dirty job site—then feel free to give them a good clean!
Avoid the Dryer with Thermal Clothes
If you’ve ever been tempted to toss your thermals in the dryer, let this be your intervention. The high heat and the action of the dryer will loosen and pull out fibers, reducing their ability to keep you warm. If your items are made with wool, the dryer might even shrink them.
Check your manufacturer's instructions before deciding what to do but best to dry them by laying them flat or hanging them on the line. This helps to maintain their shape, elasticity, and warmth.
No Ironing!
Happily (for me anyway because I do not like to iron), your thermals do not need ironing. The heat and pressure from the iron might squeeze the fibers of your thermal wear together, reducing their ability to insulate you against the cold.
Fold or Hang?
Depending on the item, once it's dry, your best bet is to fold it carefully and put it away, to ensure no stretching of the fabric. Outerwear like jackets and vests can be hung for storage.
Wear and Tear: Keeping the Cozy Going
No matter how careful you are, thermals can eventually show signs of use—especially if you’re like me and want to wear them everywhere, all winter long. Base layers are made to be durable, but wearing them for multiple days or even sleeping in your thermals (which, by the way, is a fantastic idea for staying warm on camping trips) can stress those fibers.
The best solution? Repair small issues quickly before they turn into big ones. Got a tiny hole or an unraveling thread? Grab a needle and give your thermals a little TLC. A small mend here and there will keep them going longer ensuring you stay cozy for a very long time.
Save the Socks!
Thermal socks are like old friends—dependable, comforting, and, let’s be honest, a little bit vulnerable. If your home has rough surfaces (like hardwood floors or uneven tiles), wearing them on their own may cause pulls and tears.
Slippers to the Rescue
Slippers are a great way to extend the life of your socks. Grab a pair of Heat Holders® slippers and your feet will be cozier, your socks will be protected, and you’ll even be able to step outside for the mail or to let your dog into the yard. Regularly wearing slippers will protect your socks and help them last and last.
Sturdier for Work
There’s a sock for every job. If you’re shoveling snow or working on a job site, choose a pair of socks that’s reinforced and ready for the job, like Heat Holders WORXX® socks. These socks are built tougher, which means they’ll work as hard as you do while keeping your toes cozy and warm.
Storing Your Thermals in the Off-Season
At some point, spring comes knocking, and it’s time to say goodbye to your thermal companions for a few months. Before you put them away, make sure they’re clean. Storing dirty thermals means trapping sweat, oils, and smells, which will only become more challenging to get rid of later.
Find a cool, dry place to store them—somewhere they won’t be squashed or exposed to too much sunlight. A drawer or a storage box will work wonders for keeping them in good shape until fall comes round again.
Thermal Maintenance—The Secret to Long-Lasting Warmth
Taking care of thermal clothes is more about being mindful than anything else. They may be designed to tackle the elements, but a little bit of gentle care goes a long way to keeping them in top condition. Wash them with care, avoid the dryer, fix little problems before they get worse, and store them thoughtfully. Follow these simple steps, and your thermal wear will be your cozy companions for many chilly seasons to come.
