Boiled Wool – Material, Warmth & Care

What is boiled wool?

Boiled wool is a fabric made of wool that, through a special process – fulling – gains a particularly dense, stable structure. By felting the wool fibers, the material becomes water-repellent, windproof, and at the same time breathable. This makes it one of the most popular fabrics for baby jackets, overalls, and children's clothing – especially in the colder months.

Another great advantage: boiled wool is naturally self-cleaning. Wool has natural dirt-repellent properties, so boiled wool clothing needs to be washed much less frequently than conventional fabrics. This protects the material – and the environment.

What temperature range is boiled wool ideal for?

Thanks to its temperature-regulating effect, boiled wool is very versatile. Here's a guide for babies and toddlers:

• 0 to 10 °C (cool to cold): Boiled wool jackets and overalls offer optimal protection – without your child sweating. A light long-sleeved bodysuit underneath is often perfectly sufficient.
• -5 to 5 °C (cold winter days): Boiled wool works well, especially for active children. For longer outdoor stays or quieter children, additional layers such as a fleece top are recommended.
• Below -5 °C (very cold): Here, boiled wool should be combined with warming layers – e.g., thermal underwear, fleece, and a boiled wool hat. 🧢

Important: Pay attention to the layering principle and your child's activity level. A child in a stroller needs more warmth than one who is actively playing.

Properly caring for boiled wool 🧼

With proper care, boiled wool clothing lasts for many years. The most important principle: wash less, air out more often.

1. Air out instead of washing

Boiled wool partially cleans itself. Simply hang the garment outdoors overnight – preferably in cool, damp weather. This reliably removes odors and protects the fibers.

2. Gently remove stains

Light soiling like mud or dust can be easily brushed out after drying – preferably with a soft wonder brush. For more stubborn stains, treat with lukewarm water and a little bar soap, mild wool detergent, or baby shampoo (neutral pH protects the fibers).

3. Hand wash – gentle & effective

If washing is necessary, always do it by hand:

1. Fill a basin with lukewarm water (max. 30 °C) and wool detergent.
2. Submerge the garment and let it soak for a few minutes.
3. Gently press it through the water – never rub or wring!
4. Rinse thoroughly with clear water.
5. Gently squeeze out excess water, then dry lying flat on a towel – not on a heater or in the sun.

4. No washing machine! ⚠️

Please never wash boiled wool clothing in the washing machine – especially if there is an embroidered appliqué. The fabric will warp, lose its shape, and its valuable properties will be lost.

5. Lanolin treatment for renewed freshness 🧴

After several washes or if water repellency decreases, a lanolin treatment helps:

• Dissolve 1 tsp lanolin in 1 liter of warm water, add a dash of wool detergent as an emulsifier.
• Soak the garment for 5–10 minutes, gently squeeze it out, and dry it lying flat.
• For lined clothing: Pour the solution into a spray bottle and spray the outside evenly.

6. Remove pilling 🧶

Small knots (pilling) can form due to friction. These can be easily removed with a lint brush or a fabric shaver, and the item will look new again.
