Core Fabrics |
UltraWeave™ / UltraStretch™
- Ultra™200X (Main Fabric): Made from UHMWPE fibers (similar to Dyneema), it is several times stronger than traditional nylon. Constructed with a three-layer composite structure (X-ply yarn + waterproof film), it offers lightweight durability, abrasion resistance, and tear resistance.
- Ultra™400X (Reinforced Base): Provides enhanced abrasion resistance, designed to withstand prolonged ground dragging and friction against rocks.
- UltraStretch™: A blend of UHMWPE fibers and Nylon 66, delivering high elasticity and durability.
Ergonomic Design | Comfort & Stability
- The Ultralight Composite Frame System features a dual-track aluminum alloy tube frame (22g each) for a lightweight yet sturdy structure. A carbon fiber rod enhances back panel stability, with adjustable height via the shoulder straps for an optimal fit—perfect for long-distance trekking.
- EVA High-Support Foam Padding in the shoulder straps and hip belt for enhanced comfort and weight distribution.
- Elastic Shoulder Strap Pockets for quick access to a water bottle without removing the backpack.
- X-shaped Hip Belt with an adjustable angle, ensuring a secure fit across different body types.
- UHMWPE Reflective Daisy Chain (Front Sides): Compatible with the AC-K03 bungee cord to secure trekking poles, umbrellas, ice axes, and other gear. The reflective feature enhances visibility and safety at night.
- UltraStretch™ Fabric Storage (Sides & Front): Convenient for storing rain jackets, insulation layers, water bottles, headlamps, and other frequently used items.
- Y-Strap Top Compression System: Secures items at the top of the pack with a detachable loop to prevent slipping.
