Kids Thermal underwear

More fun during sport with thermal underwear for kids

What works for you also works for your offspring: thermal underwear for kids is the best prerequisite for a pleasant body climate. This is the only way to reliably wick away the moisture that inevitably occurs during sport and exercise. However, the basic prerequisite is that all layers are made of functional material - from thermal underwear to shirts, jackets and trousers.

Functional underwear for kids absorbs moisture from the skin over a large area, the special fibres transfer it in the form of water vapour to the next layer of clothing and this in turn to the layer above until the moisture can escape into the air.

Cotton, on the other hand, remains damp for a long length of time once your child has started to sweat. As long as it keeps moving and produces heat, this is not a problem. But during so-called stop and go activities, they will quickly freeze - and catch a cold.

Functional underwear for kids

As with adults, ski underwear or thermal underwear for kids must lie directly against the skin. This is the only way to guarantee that moisture is reliably wicked away to the outside. As thermal underwear for kids is always made of elastic materials, this is easy to achieve.

Merino or synthetic fiber?

This is not just a question of faith - natural fibre or synthetic fibre - the feeling of comfort on the skin also plays a role.

Although merino wool is so fine and soft that most people find it comfortable against the skin, your kids may find pure new wool scratchy or at least uncomfortable. The advantage of merino wool is that it loses unpleasant odours overnight if you hang it up in an airy place. Merino underwear for sport is therefore ideal for activities lasting several days with constant exertion. Merino wool dries more slowly than synthetic fibres, but significantly faster than cotton.

Properties of merino wool

• warms better than synthetic fibres
• feels soft and cosy
• does not retain the smell of sweat
• forms pilling knots after repeated tank tops<
• shrinks if washed too hot

Sports underwear made from polyester, polypropylene or polyamide impresses with its excellent moisture management, making synthetic fibres superior to natural products. These fibres are shaped during production in such a way that they can absorb and release moisture, making them feel dry.

Properties of synthetic yarns

• Warmthens only moderately
• Holds its shape for a long time, does not wear out
• dries quickly and does not stick to the skin
• smells quickly of sweat and must then be washed
• very durable and long-lasting

The right decision

When buying long briefs or a long-sleeved shirt for your offspring, the choice of material depends on whether you are going skiing or hiking in the mountains. Skiing is a typical stop-and-go sport; when you're queuing at the lift and then going up the mountain, there are breaks with little movement during which the body cools down. This is where synthetic thermal underwear for kids has an advantage. It is usually also possible to wash unpleasant-smelling underwear on a skiing holiday.

For long mountain tours, where the load is even and rather soft, sports underwear made from the soft wool of merino sheep can be more favourable. Kids like the natural feel of merino underwear. The smell of sweat doesn't stick and is released from the fibres if the sports underwear is allowed to air dry overnight.

Transa offers a range of thermal underwear for kids. Whether synthetic fiber or wool, it is always a valuable purchase if it is selected to suit the activity.
