We've designed this pack for big adventures so you can go long in terms of storage, comfort, and functionality. The Adventure Pack 20L features a zipper secured roll top and compression system which allow it to adjust from 15 to 21 liters, and make it versatile from short adventures to epic! Most notably is our load leveling system which stabilizes by compressing the pack vertically and horizontally. 

Front: The chest pockets fit plus sized phones and 600ml soft flasks. The two small pockets in front of the flask pockets are for gels/trash/etc and the two shoulder pockets are for your phone, chapstick, and nutrition. The elastic chest harness works wonderfully for ladies and just as well for guys. Sizing is versatile from very petite up to about a 52" chest.

Right side: Has a 9" long zippered opening for access to maps, jackets, headlamps. The pocket reaches across the pack which creates an interior baffle as well as a large pocket. 

Left Side: Features a large pocket which holds most any water bottle or flask, and the 1" bar tacked nylon on the back works great for holding trekking poles with our optional Trekking Pole upgrade. 

Bottom: Features a 20mm attachment system for sleeping pads and additional gear. 

Interior: The interior has 3 compartments. 1st is the bladder pocket which holds a 2L bladder (included) but can hold a 3L also. 2nd is the main cargo for bulky gear, and the third is for light jackets. 

Note: The default pack does not come with Trekking Poles.
