Stay warm with
insulating clothing

No matter what activity you enjoy, staying warm is just as important as being comfortable or having fun! In fact, staying warm is a matter of safety. Read on for valuable insights into the power of insulation during cold weather. 

Down vs synthetic

Different activities and types of weather demand different types of insulation. Both down and synthetic filling have pros and cons worth learning more about when deciding what to wear on your next adventure.


Down insulation

Down is not the same as feathers. It's a material from the undercoat of birds, a natural material with amazing warming and ventilating capabilities. In production the down is formed into clusters that both keeps the warm air trapped while at the same time allowing the air to travel through so that you don’t get overheated. Down clothing is also “feathery” light keeping you flexible and comfortable all day without weighing you down. Down clothing is optimal in dry conditions, a downside is it takes longer to dry and isn’t as efficient at repelling moisture. The warming capabilities of down clothing are often described by its fill power.

Synthetic insulation

Synthetic insulation is made of synthetic fibers that are formed into similar types of clusters as those in down clothing. This means synthetic insulation works in similar ways as down, keeping the heat from escaping too far away from your body. Clothing made in synthetic materials are sometimes a little heavier than down clothing but are much more resistant to moisture and also dries faster. 50-100 g/m² is usually enough insulation for mid layer-clothing whilst 100-200 g/m² will keep you warm during those really cold days.

Synthetic jacket
A material made for more intense activities. It keeps you warm and dries faster.
+ More resistant to moisture
+ Dries faster
+ Effective for highintensity activities
- Heavier than down

What is fill power?

Down fill power describes how effective the garment is at retaining heat while still feeling lightweight: in other words, its quality. A higher fill power results in a fluffier feel and warmer jacket. This occurs when the down clusters are fully expanded inside the garment. A general tip is to look for a jacket with a fill power rating of at least 550, then it will be both warmer and more comfortable. 

What is fill weight?

The fill weight of down describes how much down the product contains. Just like fill power, fill weight plays an important role in the warmth and comfortability of a down product. The fill weight indicates how soft or firm a product is, as well as how easily it can be compressed. A light down jacket is easier to compress, whereas a heavier down jacket is warmer.
