The Warmth Layer You're Missing

Winter dressing in Australia is underestimated. Not because it doesn't get cold — it does — but because most people are working with the wrong tools. TAION makes the one piece that changes the equation: a Japanese inner down, cut slim, filled with 800FP down, and designed to disappear under whatever you're already wearing.

A Japanese Brand With One Obsession

TAION was founded in Japan in 2016 with a single focus: inner down, done properly. The name comes from the Japanese word for body temperature — 体温 — and that's the whole brief. Not outerwear. Not fashion. The layer that sits between your base and your outer, managing warmth without adding bulk or changing the silhouette of what's on top.

At the time, this category barely existed as a considered product. Lightweight down for layering was either prohibitively expensive technical gear from outdoor brands, or cheap fill that compressed immediately and lost its loft. TAION identified the gap and built into it — garments with high-grade fill, minimal construction, and a cut engineered specifically to be worn under other clothing.

Why Fill Power Matters

Fill power is the measure of how much space one ounce of down occupies — the higher the number, the better the down's ability to trap air and insulate without adding weight. Standard down products typically run around 600FP. TAION's Military line uses 800FP, which puts it in the same territory as technical alpine gear at a fraction of the weight and profile.

The practical difference is significant. A 600FP inner down at the thickness required to actually keep you warm adds visible bulk under a jacket. An 800FP piece at the same warmth rating is noticeably thinner. When you're wearing a Merz b. Schwanen tee, an overshirt, and a chore coat, an inner down vest or jacket at 800FP adds meaningful warmth to that stack without changing how any of it fits.

The Military Line

TAION's Military line is the one we stock at The Rake, and it's the range that best represents what the brand does well. The silhouettes are restrained — V-neck zip jacket, vest — in a nylon shell with a matte finish and a close, intentional fit. Nothing decorative, no unnecessary seaming, no logo placement that announces itself. The military reference is present in the palette and the cut, but worn quietly.

The V-neck opening is a considered detail. Most inner down pieces use a standard crew or mock neck, which creates a visible collar above a shirt or jacket opening. The V-neck sits below the neckline of almost any outer layer, which means there is no visible layering tell. From the outside, the stack just looks right. From the inside, you're considerably warmer.

How To Layer It

The TAION vest is the more versatile starting point. Sleeveless, it adds core warmth without restricting arm movement or adding bulk at the shoulder — the two places where layering most commonly goes wrong. It works under a shirt worn as an overshirt, under a structured jacket, or under a Carhartt WIP chore coat on a cold Newcastle morning.

The jacket adds sleeve coverage for colder days and works particularly well under a less structured outer — a coach jacket, a canvas overshirt, or a lighter wool layer. The 800FP fill means neither piece needs to be thick to be effective. They pack flat, they wash easily, and they last.

A practical winter stack: Merz b. Schwanen 215 as the base, TAION vest over the top, Universal Works overshirt over that. On colder days, swap the overshirt for a heavier outer. The TAION is doing its job invisibly in the middle — which is exactly the point.

Sizing

TAION runs on Japanese sizing, which tends to be cut closer than Australian or European equivalents. For the inner down to function correctly — sitting close to the body, not bunching under outer layers — you want it fitted but not restrictive. If you're between sizes, go up one. Come into the store and we'll size you correctly.

A Note On Care

TAION pieces are hand washable at home in cold water. Dry flat or hang — do not tumble dry on high heat. The down will re-loft naturally as it dries. Store uncompressed when not in use to maintain loft over time.
