after a long, continuous 6-hour session with lots of hiking & no sitting/pack-off breaks at all, have to give the Gura Gear Kiboko 22L+ two enthusiastic thumbs up!
very well-designed & very light, took a few mins to get used to the design but everything makes sense & you can almost tell it was designed by a wildlife/travel photographer especially for long-lens shooting.. in particular, i was impressed with how easy it was to tighten the front straps on the fly & how easy it was to pop the bag on & off.. the butterfly zippers at the top is a great idea, i was able to keep the pack on one shoulder, reach in quickly with one zipper half opened to grab my extenders..
it balances much better than I thought it would, though my sore shoulders wouldn't tell you it distributes weight perfectly like a high-end hiking backpack might. this is a minor thing though, as I didn't expect a camera pack to compare with a full out extreme-survival backpack - plus i'm sure i'll rarely go 6 hours straight carrying the following:
1Ds3, 1DmkIV, 12mm Ext Tube, 1.4x III TC, 2x III TC, Zeiss 21mm, 135L & 500L (mkI) all snugly inside, plus a Manfrotto monopod & a large bottle of Gatorade on the left/right outside pouches..
got lots of keepers today so that makes me even happier =) hopefully over time i'll be able to say that the Gura Gear pack is durable + stands the test of time as well..
thanks everyone for the recommendations! (I'll definitely get a 30L when I size up on supertelephoto lenses in the future)
