One can find plenty of space, both in the main compartment and above the storage space for "normal goods".
The main compartment is a bit inflexible divide because the supplied partition walls are not so easy to peg bar as with other products that I already had. But the Velcro is so strong that you can be all right bend.
What's also good is that (ie the side to open, without removing the backpack) him as Slingshot can use.
And a tray is above gewidment the raincover, which I find well (especially because it is not particularly immune to rain, according to statements of various reports)
What I do not like so much is that it laterally for 0.5 liter bottles are not clamping power - just like my Tamrac Adventure 7 (why have saved I do not understand, should be in the price already in it).
And the tripod mount is a joke and not actually useful - one can but the value truncated something with their own belts.
But the absolute failure is the "tightness" in the interior. When I was back on a sunny day to walk and as usual had my 2 small thermos flasks in the upper compartment and the Sony A77 rausholte after an hour with 16-50mm lens, everything was soaking wet. Disk - but the lid of the thermos had jumped and therefore become leaky - so as I wandered, is "thank God" only mineral water completely in the lower compartment secured. Thanks to the Weathersealing the camera and lens that only a "teaching program" and no longer. The camera will continue unabashedly and without a murmur and the sun has dried out the unit within 10 minutes again. As you start to sweat.
Conclusion: Anyone looking for a spacious backpack with good workmanship and in no need of tightness of the backpack (exterior and interior) sees may drag it into consideration. But it is way overpriced for this service, as it would have also brought almost a few thousand euros to water damage.
Who is like to go outside and wants to worry about the weather and sometimes in the rain enjoy adventure experiences, you should look for another product.
