The main compartment has an array of adjustable padded spaces including space for a camera with lens attached (up to about 35 cm long), and space for about 4 more lenses or flash units. All the spaces can be adjusted by moving the velcro-edged spacerts, and the entire interior is heavily padded to ensure lenses don't knock into eachother and cause damage. There are strong elastic velcro straps to hold your camera in place to ensure it doesn't fall out when you open the bag.The smaller front compartment has even more space for storage - great for things like spare batteries, memory cards, lens cleaner, car keys and anything else you might need to carry on your photographic adventure! As a bonus, there's also a waterproof cover on a little tether that can be unfurled and wrapped around the bag to protect it form the heaviest of downpours.Outside the bag, there are pockets on either side. One boasts straps that allow you to carry a tripod.The pack, fully loaded or otherwise, is very comfortable to wear, even for extended periods, making it ideal for the travelling photographer.The bag exudes style and quality, with attractive branding and flashes of orange trim making it stand out from the competition. I have no qualms about using it to carry my full kit valued at around £2000.
