🏷️ Product Features

Patented Arc™ Curved Ventilated Carry System: Tension-adjustable carbon fiber frame arcs the pack away from your back, creating a ventilated air gap that drastically reduces heat and sweat buildup while efficiently transferring weight to the hips.
Revolutionary Ultra Woven Fabric: Woven with UHMWPE (Ultra-High-Molecular-Weight Polyethylene), offering an incredible strength-to-weight ratio, superior abrasion and tear resistance compared to traditional Dyneema® (DCF) or Cordura®, and exceptional waterproof performance.
Fully Precise Sizing Adjustments: Torso length and hip belt size can be independently selected and fine-tuned for a perfect fit regardless of body type, ensuring an exceptionally stable load-carrying experience.
Ergonomic 3D Padded Shoulder Straps & Thick Lumbar Pad: Equipped with highly breathable mesh and thick cushioning to evenly distribute pressure, prevent chafing, and ensure anti-slip stability during long hikes.
Factory Fully Taped Waterproof Seams: All interior seams are factory seam-taped to effectively seal out rain and moisture.
Roll-Top Waterproof Closure & Compression System: Roll-top design combined with top and side V-compression straps allows flexible volume adjustments to compress and secure the center of gravity.
Forward-Slanted Single-Handed Bottle Side Pockets: Angled side pockets enable smooth, single-handed access to water bottles or trekking poles on the trail without taking off your pack.
High-Capacity Durable Front Mesh Pocket: Features a heavy-duty, abrasion-resistant elastic front mesh pocket for quick storage of wet tents, rain jackets, or frequently accessed gear.

💡 Sizing Guide

1. How to Measure Torso Length:

Measure along your spine from the C7 vertebra (the most prominent bone at the base of your neck when looking down) to the imaginary line connecting the tops of your hip crests.

2. Hip Belt Sizing Advice:

Measure around your hip bone circumference, not your pant waist size. The removable hip belt of the Arc Haul Ultra efficiently transfers load weight to your hips, relieving shoulder strain.

💡 Usage & Care Guidelines

Packing & Arc Tension Adjustment: Pack your gear and seal the roll-top closure first, then pull the Arc frame adjustment straps to flex the frame into the ideal ventilated arc shape for your back.
Cleaning: Wipe off dirt with warm water, a soft cloth, and mild soap after trips. Air dry in a shaded, well-ventilated area. Do not machine wash, tumble dry, or use harsh detergents.
Storage: Release the tension on the frame adjustment straps before storing. Store in a cool, dry place away from direct heat and sunlight to preserve the Ultra fabric and interior seam tape.
