Warm Merino Wool

Made from lightweight merino wool, these sets offer all-day warmth whether worn as standalone or as a base layer under clothing.


Breathable & Moisture-Wicking

The natural properties of merino wool in these sets provide all-day temperature regulation, moisture-wicking, and odour resistance.


Extended Coverage

These merino sets feature long sleeves, legs and an extended back for warmth and added coverage. Ideal for tucking in when needed.


Ideal for Sensitive Skin

These merino sets feature soft, itch-free fabric, tagless necks, and flat seams, making them ideal for sensitive skin.

What material are these sets made of?

These sets are made of 80% Wool (Merino) and 20% Polyamide.

Why is it not 100% Merino Wool?

Our base layer set blends Merino wool's thermal and breathability properties with a 20% polyamide blend for enhanced product durability over repeated wash cycles.

Can I order different sizes or color combinations in the pack?

In this set, you can only choose the same size and color for both pieces. If you wish, you can order them separately on our Danish Endurance Amazon Store.

What size should I choose?

Our merino base layer set features a tight fit. For a looser fit, size-up. Always refer to the size chart in the pictures for accurate measurements.

How should I wash these sets?

These sets can be machine washed on a gentle cycle at max. 30°C/86°F using wool detergent. Avoid bleach and tumble drying. Hanging outside overnight refreshes the wool and extends garment life. Store in daylight and fresh air to deter moths.
