Merino Wool – Nature’s Most Intelligent Fibre
By Amanda Hjalmarsson
There are few materials as rewarding to build a wardrobe around as merino wool. It is a fiber that, all by itself, manages to balance technical performance with an unsurpassed elegance. The merino sweater is not just a garment; it is a faithful servant that works just as well under a blazer at the office as it does over a t-shirt on a casual Sunday. In this guide, we dive deep into why this natural material is a cornerstone of Scandinavian style and how you can make your garments last year after year.
TL;DR
Merino wool is a versatile natural material that regulates temperature and repels odours. By choosing 'Extrafine' quality and washing sparingly, your garments can maintain their shape and softness for years.
- Merino wool breathes and regulates heat naturally.
- High-quality merino (Extrafine) features thinner fibres that do not itch.
- Wool is self-cleaning and benefits more from airing than frequent washing.
- Always store knitted garments folded to maintain their shape.
- Always dry wool flat after washing to prevent the fibres from stretching.
Why Merino is the Ultimate Fibre
Unlike standard wool, which can sometimes feel coarse or itchy, merino wool consists of long and extremely thin fibres. This results in a silky-smooth feel against the skin. However, its primary strength lies in its intelligence. Merino is an active fibre that reacts to your body temperature. It keeps you warm when it is cold, but thanks to its moisture-wicking properties and breathability, it keeps you cool as the temperature rises. This is why a fine merino jumper is the perfect layering piece all year round.

What Defines High Quality?
When we speak of 'Extrafine' merino wool, we are referring to the fibre's diameter, measured in microns. The lower the micron count, the finer and softer the wool. For Hansen & Jacob, the choice of yarn is a matter of both comfort and durability. High-quality merino should possess a natural lustre and an elasticity that allows the garment to recover after use. If a jumper loses its shape after just one day, the fibres were likely too short or the knit too loose.
Styling the Merino
A merino knit is the cornerstone of any 'Upgraded Casual' look. Try wearing a crew neck merino sweater, the Refine Crew Neck Knit, over our white Classic Oxford Shirt paired with the 5-pkt Cut n'Sew Classic Cord for a timeless office ensemble. For a more informal flair, combine an extra fine merino wool overshirt, the Knitted Overshirt, with the Eltone Check Shirt and our 5-pkt Cut n'Sew Bormio Print. It offers a sophisticated texture and a decidedly more relaxed feel than your standard blazer.

Caring for Your Wool – Making it Last
Wool is a fantastic material even from a maintenance perspective. It is naturally dirt-resistant and rarely needs washing.
1. **Air it out:** Often, hanging the jumper in fresh air overnight is enough to make it feel new again.
2. **Washing:** If you must wash, use a dedicated wool cycle and a detergent suited for wool and silk (enzyme-free).
3. **Drying:** Never wring out a wet wool jumper. Instead, press the water out with a towel and lay it flat to dry on a level surface.
4. **Storage:** Never hang knitted garments on a coat hanger for extended periods. The weight stretches the fibres and creates marks at the shoulders. Instead, fold them and store them flat in your wardrobe.

Luxurious Alternatives
For those seeking an additional level of softness and warmth, our yak wool and cashmere knits are fantastic complements to a merino wardrobe.
Frequently asked questions
Why do some wool jumpers itch while merino doesn't?
It depends on the thickness of the fibre. Standard wool has thicker fibres that do not bend when they touch the skin, creating an itchy sensation. Merino wool has much thinner fibres that are soft and flexible.
How often should I wash a merino jumper?
As seldom as possible. Airing is usually sufficient thanks to the wool's natural oils that repel odour and dirt.
