The Phantom 2.0 builds on the genius conception of the best-selling Phantom pack which became an instant hit for hyperlight, intense excursions like peak bagging, trail running and long alpine rock routes. Front compartment, side mesh pockets, accessory mesh pockets on the waist belt and shoulder straps, new light and strong fabrics, and new materials for the shoulder straps and back panel to increase breathability and comfort. The Phantom 2.0 is a perfect summit pack for multi-day climbing excursions or long alpine hikes where the layering systems hit both ends of the spectrum. When not in use, the Phantom 2.0 packs into its own internal security pocket that can then be carried around the waist or in the lid of a larger pack. The main compartment is 15 liters of open stowage and the new front zipper pocket adds an additional 3 liters for 18 liters total. Extra layers and essentials can be carried in the side mesh pockets and small accessory pockets on the shoulder strap and waist belt. The waist belt and chest strap maintain a very low profile for a minimalist fit, especially useful when being worn with a harness. Bungee straps on the back help with load compression or can be used to carry extra layers. Lightweight bungee straps to carry trekking poles, reflective highlights for low light visibility and full hydration compatibility round out the features on this welcome new addition to the Essential line.
