Excerpt: The backpack is very sturdy, with one exception. I think the quick access flap (to get to your camera quickly) is pretty flimsy. Additionally, those zippers tend to open by themselves over time, which I don't like. Otherwise, the backpack is sturdy, there is plenty of room, and I'd recommend it.
Pros: Adjustable Harness, Roomy, Strong Construction
Summary: I needed a backpack for my Nikon D7000 with 18-105mm lens, 70-300 VR lens and 50mm prime. Plus i needed a back with seperate compartment for other items , and a bag that can accomodate my future lenses. Am more than satisfied with the bag. It still has space for 2 more lenses of medium size.
Summary: Cómoda, bien acolchado, mucho espacio, materiales de gran calidad, y encima tiene un diseño moderno y bonito. Tengo también una lowepro, que aunque pertenece a un segmento diferente, en cuanto a calidad y diseño gana vanguard de largo.
