In the topsy-turvy world of insulated jackets, synthetic fills have improved markedly in recent years and are now nearly as warm, and almost as compressible and light, as down insulation. Meanwhile, down treated with a hydrophobic coating is edging out the synthetics’ warm-when-wet advantage.

Insulation

Once bulky and non-compressible, synthetic insulation has come a long way and now offers similar performance to down insulation. At the same time, down is being treated with hydrophobic coatings which prevent it from clumping so it dries more quickly and can still perform, sub-optimally, when wet. Overall, down still offers superior warmth to weight.

When choosing a down insulated jacket, take note of the loft, or 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 with less fill required to achieve it. 

Baffles 

Down jackets use baffles to keep the fill from moving around. Some synthetic garments also use baffles as well as other innovative techniques like quilting and tuck stitching to hold the insulation in place. New seamless baffles reduce heat loss through stitching.

Hoods

Insulation-filled hoods trap warm air around your head without blocking visibility. Jackets suitable for climbing will have hoods that can be worn over or under a helmet.

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. Some are lined with a fleece-like fabric for comfort and house the zip in a ‘garage’. 

Pockets 

Two handwarmer pockets and a chest pocket are the norm. Some jackets have internal organiser pockets. The lighter, more compressible jackets will stuff into one of the pockets when transporting. 

Fabrics 

The shell fabric should have a durable water repellent (DWR) coating to increase water-resistance. Breathable high thread count fabrics prevent down poking through the garment. Some are windproof to better trap warm air inside.

Storage

All insulated jackets – whether down or synthetic – should be stored out of their stuff sacks to encourage maximum loft and long-term performance.

Where down insulation comes from 

Most of the world’s down comes from China, where feathers are collected as a by-product of the meat industry. Once birds are slaughtered for food, their feathers are removed and cleaned for use in products such as clothing and bedding. 

Some companies claim to only use down which can be traced from farm to feather. Patagonia uses what it calls the ‘Traceable Down’ method, and The North Face, Arc’teryx, Outdoor Research and Montane partner with Allied Feather and Down, which follows the Responsible Down Standard, auditing each step of their supply chain to ensure animal welfare.

Macpac and One Planet use the International Down and Feather Laboratory to audit their down and assure it is ethically-sourced. Cactus Outdoor’s down is ethically harvested from Germany, while Earth Sea Sky and Marmot source their down from China. 

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