What Thermore does

Thermore is a family-owned Italian thermal insulation manufacturer founded in 1972 in Milan by Lucio Siniscalchi and now led by second-generation Managing Director Patrizio Siniscalchi. The company specializes in the research, development, production, and marketing of thermal insulation for apparel, serving outerwear brands and garment manufacturers globally. It operates through two legal entities — Thermore S.p.A. (Italy) and Thermore (Far East) Ltd (Hong Kong) — with production facilities in both Europe and the Far East, and maintains 51-100 employees.

The company's core technology is built around low-density fiber structures in which trapped air (comprising up to 97% of insulation volume) acts as the primary insulating medium, conceptually similar to double-pane windows. Thermore sells two product formats: Rolled Goods (non-woven insulation fabrics in rolls, including Classic, Thermal Booster, Ecodown, EVOdown®, Freedom, and Invisiloft®) and Free Fibers (loose fibers in bags for blown garment application, including Ecodown Fibers variants T2T, Sync, Ocean, Marble, Light, 2.0, and Genius). The portfolio is anchored by proprietary patented technologies, most notably the SR (Special Reduction) process, which reduces insulation thickness by 50% while losing less than 10% of thermal value, and Thermal Booster smart insulation that delivers 20% additional warmth at lower temperatures. Sustainability is a defining differentiator: Thermore pioneered recycled insulation in the 1980s and now uses 100% recycled polyester across most SKUs, sourced from post-consumer PET bottles, ocean-bound plastics, and post-industrial textile waste, with certifications across GRS, OEKO-TEX, Bluesign, and OceanCycle.

Thermore operates as a B2B supplier selling insulation components to garment manufacturers and outerwear brands through a direct global sales network, supported by 20+ annual trade show participations (Milano Unica, Performance Days, Functional Fabric Fair, Munich Fabric Start, Fashion World Tokyo, and others) and a four-step retailer training and certification program. Revenue is generated through hardware sales of insulation products; pricing is not publicly disclosed. The company is privately held by the Siniscalchi family with no external institutional investment identified.

Core offering

Thermore researches, develops, produces, and markets thermal insulation products for apparel, supplying outerwear brands and garment manufacturers worldwide. The product range is split into Rolled Goods (non-woven fabrics sold in rolls) and Free Fibers (loose fibers in bags for blowing into garments), predominantly made from recycled polyester sourced from PET bottles and textile waste.

Product overview

Thermore is a thermal insulation specialist for apparel, offering two main product categories: Rolled Goods (non-woven fabrics packaged in rolls) and Free Fibers (fine fibers in bags for blowing into garments). The Rolled Goods lineup includes Classic (versatile insulation with 75% recycled content), Thermal Booster (intelligent insulation that warms 20% more in cold temperatures), Ecodown (100% recycled sustainable down alternative), EVOdown® (hybrid rolled/free fiber product), Freedom (stretch insulation for active wear), and Invisiloft® (maximum warmth-per-mm slim profile). The Free Fibers portfolio includes Ecodown Fibers variants: Ocean (from ocean-bound plastics), Marble (artistic multi-color), Light (packable warmth), 2.0 (extreme volume for large channels), Genius (self-warming after washing), T2T (from textile waste), and Sync (highest versatility). All products primarily use recycled polyester from PET bottles, with Far East production only.

Broad incumbents

• Freudenberg Performance Materials: Freudenberg produces nonwoven and technical textiles including apparel insulation materials (e.g., comfortemp). It serves the same outerwear OEMs as Thermore but across a broader nonwovens portfolio spanning automotive, construction, and apparel.
• Toray Industries: Toray is a large Japanese materials company producing technical fibers, textiles, and insulation materials for apparel. It is a broad incumbent supplying outerwear brands with both fibers and finished textile solutions overlapping with Thermore.
• Teijin: Teijin is a diversified materials manufacturer with aramid, polyester, and performance fiber lines used in apparel and industrial textiles. Its technical-fiber capabilities intersect with Thermore's specialty-insulation positioning.
• DuPont (Sorona): DuPont's Sorona bio-based polymer is used in apparel insulation and fill fibers. It is a broad incumbent in performance materials with an overlapping customer base in sustainable outerwear.

Direct peers

• Allied Feather + Down: Allied supplies both natural down and recycled down alternatives for outerwear insulation. Its recycled down (RePET) program competes with Thermore's Ecodown and Ecodown Fibers lines in the sustainable-insulation category.
• PrimaLoft: PrimaLoft is a leading manufacturer of synthetic insulation for outerwear and apparel, including recycled and bio-based product lines (e.g., PrimaLoft Bio). It directly competes with Thermore in thermal apparel insulation serving the same major outerwear brand customers.
• Polartec: Polartec produces a wide range of performance fabrics including insulation and fleece technologies for apparel. It overlaps with Thermore in technical thermal materials supplied to outerwear and activewear brands.
• 3M Thinsulate: 3M's Thinsulate is a globally distributed synthetic thermal insulation used in outerwear, gloves, and footwear. It competes head-to-head with Thermore in apparel thermal insulation, leveraging 3M's scale and R&D resources.

Emerging players

• Unifi (REPREVE): Unifi produces recycled polyester fibers (REPREVE) from PET bottles, the upstream feedstock for many sustainable insulation products. It is an enabling supplier to Thermore's category and competes indirectly via recycled-fiber offerings sold to apparel brands.
