If you could only take one jacket on your next adventure, which would you choose? The answer largely depends on what activity you’ll be doing and what the weather conditions will be.
How to choose a winter coat
If you’ll be outdoors in cold to freezing conditions, choosing a down jacket is your best option.
Down is nature’s best insulator, providing exceptional warmth and breathability. A down jacket keeps you warm by trapping body heat and preventing it from diffusing into the cold air around you.
The performance of down fill is measured by fill power (learn more about fill power here). The numbers 550, 600, 750, for example, refer to the fill’s quality. Fill power is measured by the number of cubic inches that one ounce of down occupies in a climate-controlled test cylinder.
The more volume occupied by the down, the greater the amount of air trapped and the greater the insulation generated. A down jacket’s construction, such as the size of the baffles, also impacts your jacket’s insulation capabilities.
Choosing a down jacket is your best option if you want serious protection from the cold. Down jackets are ideal companions when commuting and travelling as they don't require you to layer up, but do the job of keeping you warm so that you can quickly take them off once you get to work or into a heated environment.
