This Vanguard camera backpack is meant for adventure. It easily holds a DSLR or full frame mirrorless camera with 24-70 f/2.8 attached and up to 5 additional lenses, plus has an upper gear compartment to hold lunch and a jacket and other stuff. Camera access is from the rear or the top. Easily reconfigurable to hold a camera with long lens attached -- at least a 150-500, with access through the top compartment. It is very lightweight at just 2.3 lbs. but still offers robust build quality and great gear protection. Multiple tripod attachment points and stretch pockets on both sides hold large Nalgene bottles. Tons of exterior attachment points and straps. Nicely padded shoulder straps and waist belt. Exterior dimensions 23 x 11 x 9. Fits underseat on most commercial airlines. Includes built in rain cover. It is in great condition. No rips, tears or stains. Nice medium blue color.
