Zpacks Arc Haul Ultra

The Arc Frame uses a curved carbon fiber structure to pull the pack away from your back, creating a ventilated air gap that significantly reduces sweat buildup. It also helps transfer the weight of your gear directly to your hips rather than resting it on your shoulders.

Yes, Ultra 100X is engineered specifically for high abrasion resistance and tear strength while remaining incredibly lightweight. While it is much tougher than standard ultralight fabrics, it is still a technical material that requires basic care to avoid sharp punctures.

The Arc Haul Ultra 60 is not designed with a dedicated internal hydration sleeve or hose port. Most users prefer using water bottles in the side pockets for easier access and to keep the pack's interior streamlined.

The pack is rated for a maximum load capacity of 40 pounds. However, because it is an ultralight frame, it performs best when your total base weight is kept low, typically carrying between 20 and 30 pounds for optimal comfort.

The roll-top design is highly water-resistant and will keep your gear dry during standard rain showers. However, it is not fully submersible, so we recommend using a pack liner or dry bags for critical items like your sleeping bag if you expect heavy, prolonged downpours.

The pack features an adjustable torso height system that allows you to slide the shoulder harness up or down the frame. This ensures you can dial in the fit to match your specific back length for better weight distribution.
