The Decathlon Trek 100 down puffy jacket is designed to be lightweight and packable while still providing plenty of protection from the elements.
The Trek 100 jacket has 800-fill down insulation that meets the Responsible Down Standard, and the jacket packs away into its own pocket. Not only that, but it has a water-resistant finish to keep out light rain and snow.
That, combined with a killer price, landed this jacket on our list of the best down jackets of 2021. The jacket is also available in synthetic versions.
