For large camera compartment:
The interior is characterized by different sized Velcro parts by very customizable.
Camera with 4-5 lenses and flash are not a problem. By flexible and variable fan sizes can also easily 300 or 400 lenses take (be it naturally less lenses!).
Also handy are 2 small Velcro pockets for SD cards and a zippered pocket.
Through a circumferential cushioning the equipment is well protected ...
Outside:
On each side a mesh pocket.
Front panel outside a large zipped pocket with various storage facilities for cleaning materials, filters, replacement battery, etc '
All in all a comfortable-quality camera backpack with flexible designable interior, for safe storage of camera equipment.
