Not all insulated jackets are created equally and one of the first steps to choosing the right jacket for you is understanding the different types of insulation available.
Insulated jackets typically fall into one of either two categories, “down fill” which are natural fibres taken from the underside of a duck or goose, or “synthetic” which features man-made, polyester fibres packed tightly together.
No one type of insulation is necessarily better than the other and choosing the right type for you will depend on the task at hand. This article will help explore some of the key structural and performative differences between down fill and synthetic insulation in order to help you pack the right jacket for your next expedition.
