Water repellent

  • Surface-treated outer fabric to prevent water from getting in. The water-repellent property of a fabric is its ability to make water run off its surface without absorbing it.
  • We recommend wearing a waterproof jacket if exposure to rain prolongs.
  • We recommend that you restore it after each wash.

Down benefits

  • Thermal insulation is provided by the air trapped in the down and feathers.
  • Ultra-low weight: Down is lighter than synthetic fill while offering the same degree of warmth. This saves even more weight in your backpack.
  • Ultra-compressible.

Caring for your jacket

  • 1. Machine wash, 30°F, with 2 or 3 tennis balls. Gentle spin cycle.
  • 2. Tumble dry with 2 or 3 tennis balls.

Fantastic jackets

I've had several of both the down and synthetic Decathlon offers, and they are outstanding. One note, however, they do run small. I normally wear XL or XXL, but I order these in XXXL. To the company, please keep these affordable, as the price point is perfect.

Fits like a glove, light like a feather

I saw many review mentioning that the jacket runs small and they got bigger than usual size. Most of my clothe (including jackets) is Large. Size Guide confirmed that I need Large size for this jacket and I'm glad I went with that size. It fits like a glove to my tall skinny-ish body (6'4" 194lb / 194cm 88kg). It's also noticeably lighter than REI 600 down jacket (no hood)Can't say anything about warmth as I'm yet to test it out this upcoming weekend, but so far I'm happy with the purchase.

Extremely versatile down jacket

I had to get this while it was on sale and the value of this jacket cannot be beaten. It's an ideal all season jacket in milder climates, perfect for casual hiking for using around town. Most definitely recommend sizing up for this jacket if you are used to US sizing. As someone who usually wears a men's medium, the large size was perfect for me and left a little room for some light layers underneath. The cuff design on this jacket is also excellent and seals in warmth quite well. Couldn't be happier with this jacket!
