Named After a Feather

People ask what BROOD, COVERT, HACKLE and PREEN mean. They are not invented words. Every one of them is a term from bird anatomy, and each names the piece that does the equivalent job in our range.

This is not a naming exercise we did at the end. It is where the range came from.

A raven does an alpine winter in three layers

Corvids hold their body temperature through a Sierra Nevada January without a down jacket, without a change of kit, and without going indoors. They do it in air that regularly sits well below freezing, while flying — which is to say, while working hard, generating heat and moisture, and then stopping and needing to not freeze.

That is exactly the problem a layering system solves. The bird solved it first, and it solved it structurally.

The anatomy, layer by layer

Down and brood feathers — against the skin

Underneath everything sits a layer of fine feathers held directly against the body. On a breeding bird, the brood patch is the area kept in closest contact of all. This layer is not the weatherproofing and it is not the bulk. It manages the immediate microclimate at the skin.

BROOD™ is our baselayer. Worn against the skin, midweight, cut so it is not compressive, moving moisture away from the body before it can cool. First layer of any cold-weather system, doing the same job in the same position.

Coverts — the layer over the base

Covert feathers are the small, overlapping feathers that cover the base of the wing and tail. They are the layer between the insulating down and the flight feathers — the smoothing, structuring, warmth-holding layer in the middle of the stack.

COVERT™ is a midlayer. Synthetic insulation, worn over the baselayer and under the shell. Same position in the stack, same job.

Hackles — the throat

Hackle feathers sit at the throat and neck. On a raven they are unusually long and shaggy, and the bird can raise them — a display when it wants to look larger, and a genuine thermal mechanism when it wants to trap more air around the core.

HACKLE™ is our other midlayer, and it exists as a jacket, a hooded jacket and a vest. The vest is the one that carries the metaphor properly: core insulation, arms free, warmth exactly where the bird puts it.

Preening — maintaining the outer layer

Preening is not a feather. It is the behaviour. A bird works oil from a gland at the base of the tail through its outer feathers, and that maintenance is what keeps the outer layer shedding water. A bird that stops preening does not stay waterproof, however good its feathers are.

PREEN™ is a lightweight packable waterproof parka. It is the extra shield you put on over your kit when the weather turns, and it is named for maintenance because that is what it is: not the main technical layer, the thing you do to keep the system working.

The idea carries into how we ask you to look after everything else. DWR is not permanent. Water repellency is a behaviour, not a property. You preen a shell by washing it and reactivating the finish, and a shell that is never preened stops working long before it wears out.

Talons — the part that has to hold

Talons are the one part of the animal that takes real mechanical load. Everything else is insulation, structure or surface. The talons are where it grips.

TALON™ is the 3-layer hardshell. 20K/20K, fully taped, helmet-compatible hood, pit zips, built Loose to go over the whole system. It is the piece that has to hold up when nothing else will.

The rest of the range

ROOST™ — where a bird settles for the night, insulated and windproof, built for the end of the day rather than the middle of it.

PERCH™ — the urban insulated jacket. Not the mountain, not the nest. The place in between where you actually spend most of your time.

MURMUR™ — from murmuration. A 2L insulated system that works as one piece, the way a flock behaves as one thing.

SHEEN™ — the iridescence on a corvid's wing, only visible at the right angle. A waterproof parka cut for the city, where the surface is what people see.

LEDGE™ — North, South, East and West. Ravens nest on ledges, and the four parkas are named for the four aspects, which in the mountains determine how much sun a face gets and how cold it stays.

Why bother

Because a naming system that maps onto function is a discipline, not decoration. If a new piece cannot be placed in the anatomy — if we cannot say which layer it is and what it does that nothing else does — then it is a piece we do not need to make.

That is the actual reason the range is twenty-seven pieces and not two hundred. The bird is a fairly strict editor.
