Its triple compartment design neatly manages the key components of digital photography with a rear compartment for a notebook computer (fits most 17" models) and files, and a lower compartment that accommodates a digital SLR with lens attached (up to a 105mm f/2.8), plus 2-3 additional lenses or flash units. The upper compartment holds personal accessories and cables. Tuck an MP3 player into the quick access front pocket, thread the headphones through the unique headphone port and listen to your favorite music even on the go.
