Down & Synthetic

Insulated gear uses either down or synthetic insulation, although some use both of them in their design.

Get Down with Down

Down are the fluffy clusters that are found underneath the tougher outer feathers of ducks and geese. If it’s good enough to keep them warm, then it’s good enough for us.

When people talk about down, they may often refer to it as feathers. However, feathers are only a very small proportion of the insulation. We use far more down than feather in our gear. 

What’s so great about down?

Down is made of very fine fibres that provide the lightest and most efficient means of trapping and holding air in position.

This trapped air provides an incredibly efficient thermal barrier. Its performance is unrivalled by any other natural or synthetic equivalent. Individual down clusters expand (or loft) to fill an area that is vast relative to their size. The down’s volume is then made almost entirely of trapped air, so any down filled gear remains incredibly lightweight and compressible.

Down Cluster Ratio

This is the amount of feather and down mix that is found in your down clothing.

The higher the ratio, the more down the item contains.

For our duck down gear, we have a cluster ratio of 80:20, where there is a maximum of 20% feather content. For our goose down items this ratio changes to 90:10, where the minimum down content is 90%.

The higher the percentage of down, the better warmth for weight.
