What to look for in thermal vests for kids

Antibacterial material: This will ensure your child stays fresher and odour free for longer.

Lightweight: You want a thermal vest that is lightweight enough to wear comfortably under their usual clothes without weighing your little one down.

Breathable: The fabric allows perspiration to pass out of the garment, keeping your youngster cool and comfortable.

High wicking: Look for fabric that actively wicks moisture away from your child's skin, keeping them dry during activities where they might sweat.

What is the best thermal material for kids?

Merino wool is a great fabric for thermal vests for kids. Not only is it warm but it is moisture wicking too, so keeps little one dry and comfortable, as well as being lightweight. Plus wool is naturally thermo-regulating. Another great option for insulation is fleece, which will definitely keep in the heat.

Should a thermal vest be tight or loose?

Ideally thermal vests should fit snugly to provide maximum effectiveness. If they are loose then gaps between the fabric and the skin will allow the cold to creep in. Obviously, they also need to be comfortable too and not too tight, or restrict your little one's movement. However, many are made with stretchy or flexible fabric to allow easy movement and comfort.

Are thermals good for kids?

Layers are a great way to keep your little one warm and therefore in cold weather, adding a layer of thermal underwear, in particular a vest, is a great way to ensure your child stays warm. If you are planning a trip to a chilly climate then definitely consider thermal vests and there is plenty of skiwear for kids if you are planning a holiday on the slopes. However, it doesn't have to be snowy for your little one to benefit from a thermal vest, and adding one to their winter wardrobe will ensure they are cosy when playing outside.
