Dimension-Polyant will debut two new sailcloth-derived X-Pac hyperTEC laminates at Performance Days in Munich on October 13-14, targeting mountaineering, climbing, skiing and bikepacking equipment makers with ultra-light constructions built on 100% Ultra-PE face fabrics.

The German-US technical fabrics producer, owned by Belgium's Sioen Industries since its 1966 founding, will show the first UX10 and UX20 sT constructions in Europe at booth M16. Belgian bikepacking specialist Moga Bags is one of the first commercial adopters, and the company says further brand collaborations are in development — though those remain announcements rather than confirmed programs.

What do the new laminates offer?

Both constructions pair a 100% Ultra-PE face fabric with X-Pac's Ultra-PE X-Ply reinforcement. The laminate construction provides inherent waterproofing without a separate membrane layer, according to the company.

"Using advanced fibres allows us to produce laminates that are ultra-light and have a tremendous strength-to-weight ratio, while maintaining the durability and reliability that X-Pac is known for," said Dimension-Polyant president Kenneth Madsen.

The two versions split along weight-versus-strength lines:

• UX10 — translucent white; positioned as the more versatile option, balancing low weight and durability for packs across a range of outdoor applications.
• UX20 sT — black; emphasizes strength and load-bearing performance for highly stressed uses. The "sT" denotes a single polyester taffeta backing layer placed behind the polyester film, improving handling and durability and making the lightweight laminate more opaque.

For sourcing teams, the split matters: brands specifying packs for high-load applications get a dedicated construction rather than over-engineering with heavier fabrics, while weight-sensitive programs can specify UX10.

Where does the technology come from?

X-Pac fabrics originated in Dimension-Polyant's high-performance sailcloth business, which applied precision lamination techniques to pack and equipment fabrics. The launch extends that crossover from competitive sailing into alpine and bikepacking end uses — the same transfer logic the company has used since it began adapting sailcloth constructions.

Production runs at the company's facilities in Putnam, Connecticut, and Kempen, Germany, giving buyers two regional supply points for the new laminates.

What about recycled options?

Also on display in Munich: X-Pac RX30, a three-layer laminate manufactured entirely from recycled materials. The construction combines:

• a post-consumer recycled polyester face fabric made from PET bottles;
• recycled X-Ply reinforcement;
• a lightweight recycled polyester film backing;
• a non-fluorinated durable water-repellent finish.

RX30 targets both outdoor and urban applications and ships in a wide colour range including black, white, slate, cayenne, coyote brown, evergreen, ocean blue, alpenglow, bluebell, goldenrod and plum. The non-fluorinated DWR finish aligns with tightening PFAS restrictions in outdoor gear supply chains.

Finished packs using hyperTEC and RX30 will be displayed alongside the established X-Pac VX21 at the booth, giving product developers a direct comparison across the three tiers of the range.

With Moga Bags already commercializing hyperTEC and additional collaborations in development, Dimension-Polyant appears positioned to expand X-Pac's share of the technical pack fabrics market beyond its sailing and bikepacking base.
