Have long sought "equipment" for affordable transportation option for matching my little paintball. In this case fits my playing Tippmann A5, Hopper, running, HP 0.8L bottle, mask, gloves and a small parts assortment purely without having to squeeze it in! From the perspective of an amateur photographer, I would say that at least 2 DSLR Bodies (eg EOS 7D), to at least 1 Tele and 3 to 4 smaller lenses, flash, charger, memory cards, batteries and data cables, see no problem hiding in this case. Case is very stable and torsionally rigid with circumferential seal. Hinges snap closures and carrying handle make a very solid impression.
