What is X-PAC Fabric? Complete Guide for Technical Bags and Backpacks

What is X-PAC Fabric?

X-PAC fabric is a laminated technical fabric widely used in high-end backpacks, bikepacking bags, and outdoor gear. It is known for its lightweight construction, high strength, and waterproof performance.

Unlike traditional woven fabrics, X-PAC laminated fabric combines multiple layers into one structure.

Typical X-PAC construction includes:

• Face fabric (Nylon or Polyester)

• X-PLY reinforcement layer

• Waterproof film

• Backing layer

This multi-layer construction makes X-PAC fabric stronger and more dimensionally stable than traditional fabrics.
