Engineered for Performance

Double-Knitted Interlock Fabric

Built using a 270–290 GSM Double-Knitted Interlock Fabric, Fusion Series II provides dependable insulation while maintaining flexibility and durability. Its dual-layer knit structure creates a stable fabric that feels smooth against the skin and performs consistently through everyday use.

Multi-Fibre Inner Composition

The inner composition combines polyester, viscose, silk, wool and spandex, with each fibre selected for a specific purpose. Together, they create a balanced thermal that delivers warmth, softness, stretch, moisture management and lasting everyday comfort.

Fold-Free Construction

Traditional folded edges can create unnecessary bulk beneath additional layers. Fold-Free Construction uses precision-cut anti-fraying fabric at the neckline, sleeve cuffs and hem to reduce bulk, improve comfort and create a cleaner finish.

Flat Seamer Construction

Low-profile flat seams reduce friction and pressure points against the skin while increasing durability, making the garment more comfortable during extended wear.

4-Way Stretch Performance

The fabric stretches naturally in every direction, allowing unrestricted movement while helping the garment retain its shape after repeated use.

Moisture Management

The engineered fabric helps move moisture away from the skin to maintain comfort throughout changing winter conditions and long hours of wear.
