I had looked at all comparable products from Vanguard, Lowpro and Kata and sometimes can also test by friends and again I have to say TOPTOPTOP. For me it was crucial that a 13 "notebook with a thickness of 35mm fit in. In general, the Tamrac provides a firm footing on the ground, protects all equipment perfectly. He has perfectly accompanied me on many photo trips and with his techn. FeatureN always surprised and support. For me, the Evo 8 is nothing for the times "photo holiday," he sits stable but is also a bit stiff in comfort. Just when is still a book in the back pocket. The carrying system is oversized and resemble a parachute equipment. It can accommodate about 300mm for a full-size, 2 to 50 mm lens and a telephoto until then. Also, until he suffered a small equipment and lightning are reingepackt above. All competitors I mentioned above can be wear more comfortable, but do not offer the protection and also partly not storage space as the Evo8. Suitable for a to 2-day tours, for more you need just the Evo9 or Expedition9 is only suitable for extreme tours.
