Fur. Goose down. Wool. There are a lot of natural materials that help keep us warm. But when it comes to days that start before the sun comes up and end after it goes down, you need insulation that’s lighter, tougher and warmer: synthetic insulation.

Let’s take a look at how synthetic insulation works and why it’s better than natural options.

The Basics of Insulation Technology

All insulation works the same way – it creates air pockets that trap heat next to your body. It also prevents cold air from getting through the barrier to your skin.

Synthetic insulation in jackets is made of tiny fibers that are great at forming pockets for trapping air. Not only does it provide warmth just like goose down or wool, it lasts longer – through tough days, long nights and more washes.

Why is Synthetic Insulation Better?

The many talented engineers and scientists who developed synthetic insulation designed it to address some of the disadvantages of down. Down can be expensive and bother the folks who have allergies. Synthetic insulation, on the other hand, is cost-effective and hypoallergenic. The biggest disadvantage of down? It becomes dramatically less effective at keeping you warm when it gets wet.

Even with water-resistant coatings, synthetic is still the gold standard for moisture-resistant insulation technology. If you think you’ll be encountering wet weather or working in an environment with lots of moisture, then insulated jackets with synthetic technology is your best friend.
