How to wash technical underwear: A Practical Guide for Long-Lasting Gear
Good thermal underwear is your first ally in winter adventures: it protects against the cold, keeps the skin dry, and allows freedom of movement. But there is one aspect that is often overlooked: care. Knowing how to wash technical underwear means extending its lifespan and keeping performance intact, so that every mountain outing is as comfortable as the first.
Why proper care matters
Whether it’s a base layer, a thermal top, or technical leggings, underwear works in direct contact with the skin and is put to the test by sweat, friction, and frequent washing. Correct maintenance helps preserve:
- breathability and thermal regulation,
- the elasticity and fit of the fabrics.
This way, you not only maintain performance but also reduce environmental impact by avoiding the need to replace garments too soon.
General rules for washing technical underwear
There are a few best practices that apply to all garments, from women’s thermal underwear to men’s thermal underwear: always wash at low temperatures (30°C is ideal), use mild detergents, turn garments inside out to protect them, and air dry them without using a tumble dryer. Ironing is not necessary: technical fabrics keep their shape and elasticity on their own, and the heat of the iron may damage them.
These simple steps help both women’s thermal tops and men’s thermal tops maintain their shape and function longer.
Merino wool thermal underwear: natural delicacy
Merino wool is an extraordinary fiber: antibacterial, soft, and naturally thermoregulating. But it requires a bit more care. A women’s thermal top or a merino base layer should be washed on gentle cycles, never above 30°C, avoiding aggressive spin cycles and wringing. It’s best to blot excess water with a towel and dry the garment flat, away from direct heat sources.
The real strength of Merino is that it doesn’t need frequent washing: a thermal top of this kind can be worn several times without bad odors, making it the best women’s thermal underwear for long treks and winter travel.
Audant-X®: performance that lasts longer
Garments made with Audant-X® technology combine superfine merino wool and recycled synthetic fibers. This blend not only guarantees excellent performance in the field but also reduces the need for frequent washing: Merino limits odors, while technical fibers speed up drying and maintain elasticity and shape. A choice designed for those who live the mountains intensely but want durable and sustainable gear.
Care that makes the difference
Thermal underwear is not just another layer, but the foundation of protection in the mountains. Whether it’s a thermal top, a base layer, or your favorite ski thermal underwear, durability and performance also depend on how you care for it at home.
Just a few daily habits can ensure reliable gear season after season. And when you choose a fabric like Audant-X®, you know you have an ally designed to stay with you for the long run, without compromise.
