Designed for longer days in the backcountry, the Yagi 35L can keep up with you from dawn 'til dusk.
The top zipper design allows for easy loading, where the self-locking side zip allows for quick access. With the 35, you now also have the carry option of A-frame along with the diagonal quick carry system.
The additional 10 liters will also free you of the internate debate of whether or not to bring that extra puffy or gloves!
