2020’s best insulated jackets

Featured jacket: Outdoor Research Illuminate Down Hoody $399.99. Distributed by
Everything you need to know before buying an insulated jacket.

There are two types of insulation: synthetic or down. Synthetic insulation is cheapest and will keep the user warm even when wet. It is bulkier and heavier than down, but also more durable. Modern synthetic fills are coming close to equalling down in weight and compressibility. Down still offers superior warmth to weight and now that most down insulation is treated to make it hydrophobic (it resists soaking and dries more quickly to avoid clumping), it is also able to perform in wet conditions – though not to the same degree as synthetic.

When choosing a down jacket, take note of the fill power (the volume that one ounce of down fills when full of air) – it is usually measured between 500 and 800. The higher the number, the greater the warmth and less fill required to achieve it.

Hoods improve warmth considerably by trapping warm air around your head without blocking visibility. Hoods on alpine or climbing jackets will be helmet-compatible.

Down jackets use baffles to keep the fill from moving around. Some synthetic garments also use baffles amongst other techniques to hold the
insulation in place. Seamless (welded or seam sealed) construction reduces heat loss through the stitching.

Collars and cuffs
Cuffs keep out wind and snow and can be self-closed or elastic. Insulated collars should zip up under or just over the chin. They may have a soft comfort lining at the chin.

Two hand warmer pockets and a chest pocket are the norm, though some ultralight models may just have one chest pocket. Internal pockets can be used to store items close to your body. Lighter and more compressible jackets will stuff into one of the pockets or a separate stuff sack for transport.

The shell fabric should have a durable water repellent (DWR) coating to increase water-resistance – some models even use a waterproof fabric to protect the down. Breathable high thread count fabrics prevent down poking through the garment.

Responsible Down Standard
Most manufacturers using down insulation adhere to the Responsible Down Standard (RDS) administered by the nonprofit Textile Exchange. The standard ensures:

  1. The removal of down and feathers from live birds is prohibited
  2. Force-feeding of birds is prohibited
  3. Holistic respect for animal welfare of the birds from hatching to slaughter
  4. Each stage in the supply chain is audited by a third-party certification body
  5. Only products with 100 per cent certified down and feathers carry the RDS logo

Now you know what to look for, it’s time to choose your jacket.
