Merino wool underwear - Stay dry and odor-free all day long

Have you tried packing light for a weekend trip but still want to feel dry and comfortable all day? Merino wool underwear is popular because it works close to the body, where breathability, moisture management and odor control quickly become crucial. Here's an overview of what to look for and how to choose the right set for your needs.

Merino thermal underwear is often used as a base layer, helping to manage moisture from the body and create stable comfort when you are active. The difference is typically in thickness and knit: Some models are light and versatile, while others are denser in material and feel warmer and more “thermal”.

The most important thing is to choose according to activity and intensity: The more you move, the greater the demands you place on your underwear to be able to transport moisture away and dry again without feeling clammy.

When merino wool underwear fits well, it often feels less “plastic-like” than many synthetic alternatives, and can feel more comfortable against the skin over extended periods of time. Look for flat seams and a fit that follows the body without being tight.

As a base layer, merino wool underwear is an obvious choice when you want to keep your packing simple and flexible. One set can be used for both activity and quieter days because it is designed to work close to the skin.

On trips where you switch between movement and breaks, it can be an advantage to combine the base layer with smarter equipment in the bag, so you can keep the weight down. If you also prioritize light packing and quick drying after a shower or swim, a compact, quick-drying towel can be a good companion to the base layer in the OUTDOOR backpack.

Many people choose merino wool underwear because wool itself is often associated with less odor when worn. In addition, there are textiles where odor control is supported by an antibacterial treatment. Nordifakt, for example, states that they use Polygiene StayFresh technology: a silver-based antibacterial textile treatment that is added towards the end of production and is stated to prevent 99.9% of bacteria from growing on the textile. The aim is for the textile to stay fresher for longer.

When something can be used several times before washing, it can also mean less laundry in everyday life and on trips, which saves water and energy.

Start by defining the use: Will it be for hiking, training, travel or everyday comfort? Then choose the cut and layering. Some prefer a tight fit for better moisture transport, while others want a little more freedom of movement.

Also look for transparency in production and chemical requirements, especially since underwear is very close to the skin. Nordifakt, for example, indicates production in Portugal (EU) and compliance with strict chemical requirements for textiles, as well as standards such as STANDARD 100 by OEKO-TEX and BlueSign approval.
