Down hood designed for wearing over your mountaineering helmet, adjustable with 2 systems at front and rear of jacket
Reinforced forearms
Durable component has been selected to reinforce jacket's forearms. Because these areas are heavily used during practice, the chosen component is more robust than the main component of the jacket.

    Very comfortable, lightweight and protective

    I have used this duck down jacket for 2 winter seasons in Boston, US and northeastern states. The temperature often goes below -20 degree C in winter here. The design of this jacket is so perfect that I absolutely didn't face any issues during winter with this jacket on. Sometimes I would just wear a half sleeve shirt inside and still would feel comfortable. The only drawback is, this jacket is NOT waterproof/ water-resistant. It'll get soaked in water quickly, which would be undesirable. So, you may have to remove the accumulated snow over it (during snowstorms etc). I also have washed this jacket in a laundromat washer and dryer. No issues there too.

    Malaku II Down Jacket - Red Simond

    Good size and fit, well made with good materials, light and warm. Pockets seal with zips, spacious inside pockets too. The hood fits well and the tougher material used on the forearms is a good design idea. All this at a very reasonable price, as usual from Decathlon.
