Why Thindown
The next generation of down insulation — your innovation partner.
Thindown is an innovation partner. We don't just supply insulation — we build long-term partnerships with the brands, manufacturers, and organisations that shape cold-weather performance.
Innovation & IP
The most important innovation in down insulation in a century.
Thindown is a patented continuous-layer insulation technology — the world's first down fabric — manufactured in Italy today, with New York State production planned for Q1 2027.
The next generation of Thindown launches with our new NY facility. This is not an incremental update — it is a new direction, with new capabilities for brand partners and a new benchmark for what continuous-layer down can do.

Product Performance
Warmer. No cold spots. More comfortable.
Thermal Efficiency
Warmer than any synthetic at equal weight. The most thermally efficient insulation in a uniform, continuous layer.
No Cold Spots
Loose down migrates under movement, washing, and compression. A continuous Thindown layer holds its position, delivering consistent warmth across every centimeter of the garment — no cold spots at the quilt lines.
Breathability & Comfort
Thindown enables the use of more breathable fabrics than traditional downproof constructions. Body heat penetrates the down layer; water vapor moves out. Down's natural climate control, finally unlocked.
Unparalleled Design Freedom
Design without the workarounds.
Traditional down construction is a series of compromises: baffles to contain the fill, dense downproof fabrics to prevent seepage, quilted channels that interrupt the silhouette.
Thindown removes those constraints.
- → Any shape — from jackets to gloves to sleeping bags
- → Cleaner silhouettes - quilting not required
- → Breathable — Thindown can be used with breathable fabrics
The Thindown Technology
One technology, many uses.
From 30gsm to 180gsm, with 180gsm exclusive to HiLoft. Goose or duck. Standard, blended, or custom. FR, DWR, or odor-control finishes. The same continuous-layer technology serves every cold-weather category.
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

Specialty Treatments
Unlock new frontiers in down performance
Performance finishes available across all Thindown variants for programs with specific functional requirements.
Water Repellent
DWR Repel
Durable water repellency — moisture beads off the surface, keeping the insulation dry and thermally effective through wet conditions.
Odor Control
Fresh
Anti-odor treatment for sustained-wear programs — workwear, athletic, and uniform applications where garments are worn across extended shifts.
Flame Resistant
FR Rated
FR finish for law enforcement and industrial programs requiring flame-rated insulation without sacrificing warmth or comfort.
