Hat METTE with merino wool lining

All parents want to make sure their kids are safe and warm while playing outside. Layering clothes is very important and so is the right choice of materials. But an absolute must for autumn and winter hats is a merino wool lining. Why is it so important? Let’s explore.


It’s imperative that the first layers of anything, be it clothes or hats, could deal with various problems such as feeling cold, hot or wet. This places very high expectations on materials which means first layers should always:

  • help create and sustain warmth

  • regulate body temperature 

  • whisk away excess moisture


As said before, it’s imperative that cold season headwear could keep warm and fight off cold and moisture. In order to do that it must have the right type of lining. 

While cotton is a very comfortable, soft and skin-friendly fabric for warm seasons, it’s not a very “smart” material. Cotton doesn’t “know” how to regulate body temperature or deal with moisture. Therefore you shouldn’t use cotton hats in autumn and winter. Instead it’s best to opt for merino-lined hats and merino-lined hat-scarves. There's a whole blog post dedicated to merino wool. 

But how come merino wool is such a know-it-all? The trick is to contain lots of air molecules that create an air barrier preventing body heat from getting out and outside cold from getting in. Merino wool can also drive moisture away from skin, leaving it feeling warm and dry. There’s really no industrial material that’s better than nature’s very own merino wool.

Thick merino wool lining


Yes, we determined earlier that cotton is not as smart as merino wool but it doesn’t mean cotton doesn’t have its own wonderful properties. Cotton works really well as an overlay material, because it’s soft and stretchy and creates a great fit for any shape and size head. Cotton fibers are quite dense and help create a wind barrier and when combined with merino wool, it’s a really indestructible duo.

And to all who think proper autumn-winter hats should be thick and bulky – it’s a new day and a new dawn for the clothing and headwear industry. Merino wool can feel thin and airy but it works so much better than any artificial material ever created. It feels light and great and has the widest range of wearing temperatures which saves you actual money. What could be better than using the same hat during autumn, winter and spring? Win-win-win.


  • Thin merino lining. Thin merino wool works best between temperatures of -7 to +5°C / 19.4°F to 41°F. It’s best for kids who tend to sweat easily. 

  • Thick merino lining. Thick “heavy duty” merino wool comes in handy when the temperatures drop below -7°C / 19.4°F. It’s woven with a different method that enables the fibers to be more dense and therefore block cold and wind.

Merino wool and cotton are a match made in heaven. One can regulate body temperature, maintain warmth and whisk away excess moisture. The other supports and elevates these wonderful properties and creates a wind barrier. Now that you know these important things, it’s high time to go shopping. Do that in Breden's e-shop.

Merry merinos!
