Thindown · Down Without Compromise
A Revolution In Performance Insulation
Thindown is down without compromise — a uniform layer of real down in the form of a fabric that does not require quilting or baffles, and will not leak or clump. The result is incredible warmth without bulk, breathable comfort, and no cold spots.
Warmer
Thindown is substantially warmer than synthetic insulations and down construction of comparable weight. Stable, uniform loft without quilting means no gaps in coverage, thin spots, or holes.
No Cold Spots
A continuous insulation layer without stitch lines delivers uniform warmth across every centimeter
More Breathable
Thindown jackets can be more breathable than traditional downproof construction — unlocking down's natural climate control.
What is Thindown?
Down is the best natural insulator. We improved it.
Down is the world's highest-performing insulator, but down can shift and clump, creating cold spots. Thindown transforms premium down into a continuous insulation layer, the world's first down fabric.
Thindown provides even warmth, more breathability, and unparalleled comfort across a range of cold weather applications.
Thindown is the only down fabric technology in the world, and is protected by multiple patents.
Three Reasons Thindown Performs
Warmer. Breathable.
No Cold Spots.
01
Warmth without weight
Down is the most thermally efficient natural insulator on earth. Thindown delivers it in a continuous layer — no stitch lines, no cold channels, no fill migration. Warmer than both quilted down and synthetic fills at similar weights.
02
No cold spots.
Cold spots form at every seam in a quilted jacket. Thermal imaging shows the gaps clearly — dark patches where stitch lines interrupt insulation. With Thindown, warmth is uniform edge to edge.
03
Made to move.
Thindown can be used in any shape, quilted or quilt-free. A stable insulation layer opens up more breathable fabric options than traditional downproof construction. That means less sweat and faster dry times.
The Thindown Line
One technology, many uses.
Every variant is a continuous down sheet — engineered for different performance demands, from ultralight athletic layers to heavyweight sleep systems.
The original technology.
Thindown Core
Real down in a continuous sheet — goose or duck, any weight. The flagship thermal technology where most partnerships begin.
Goose or duck · 30–150gsm
View details →Maximum warmth-to-weight.
Thindown Ultra
Premium fill power down for the highest thermal performance per gram. Purpose-built for extreme cold and alpine programs.
30–150gsm
View details →Down + fiber blends.
Thindown Hybrid
A continuous layer combining down with other fibers. Sorona® and NAIA are optional blend choices; contact our team to discuss your program.
Down + fiber blend · 45–150gsm
View details →High-loft. Uniform coverage.
Thindown HiLoft
Engineered for extreme cold weather applications, sleep systems, and home use — visible loft with continuous-layer thermal performance. HiLoft series Thindown is manufactured with more distance between each cluster, leading to added loft at the same weight.
High-loft down · 60–180gsm
View details →Coming 2027.
Thindown Dimension
Thindown engineered for footwear and glove applications where dexterity, low bulk, and high clo are paramount.

Responsible Down Standard
All down fiber is RDS-certified. Geese and ducks are raised humanely, and the full down supply chain is traceable.
OEKO-TEX Standard 100 Class 1
The most stringent chemical safety tier — every component tested for harmful substances, from raw material to finished product.
Global Recycled Standard
Chain-of-custody verification for recycled-content variants. Available on Thindown Hybrid.
Built for Manufacturers
The insulation that handles like a fabric.
Thindown processes on existing cut-and-sew infrastructure — no filling equipment, no clean rooms, and significantly faster production time.
Cut & Sew Ready
Available in 145cm-wide rolls up to 50m. Cuts, sews, and integrates exactly like any woven fabric on standard cut-and-sew equipment.
Clean to Work With
No feather seepage, no fill migration during cut-and-sew. Clean, controlled production conditions across every run.
Made in Italy. US production planned for Q1 2027.
Manufactured in Italy today, with New York State production planned for Q1 2027. Domestic supply chain traceability will be available for qualifying programs.
Speed to Market
Up to 30% reduction in assembly time versus quilted down — no channel-stitching, no fill injection, no specialist equipment required.
What the industry is saying
The breakthrough technology of Thindown® — coupled with the textile innovation of Sorona® fibers — can further revolutionize down applications and create a new category of insulation.

Thindown is durable enough to be machine washable, and with the feathers bonded into the fleece, there is no risk of the filling seeping out of the material.
