His camera compartment is big enough and can be customized for the most part. I have the 60D with attached 17-85, which housed safely 70-300 lens, the 50mm, the lens hood, a flash + diffuser, memory cards, USB and HDMI cables and the battery charger. Since you the SD card, the cable and the charger is also very well can accommodate in the overlying compartment where I stowed also a Lenspen and a blower, so it stays quite still space for additional lenses.
The workmanship is as expected very good and the straps on the shoulders and hips can be very easily and adapt well.
The Notebookfack "swallows" my 17.3 "laptop though only with some effort, but it fits in and seated, without having this fear must be that something will scratch or gouge. The upholstery is at this point very well.
And situated in the upper part daypack compartment offers several organizer functions of your mobile phone, pens, paper, etc. and provides next even for my needs enough space for additional accessories or easily packable clothes (a 1.5 liter bottle of water I have with getting cross placed there without the to use all the space here).
On the right side you can accommodate a 1 liter bottle in a secured network with drawstrings loose.
The zippers are water resistant under a flap and the material can easily penetrate even no water, and dries very quickly, so I can do without the missing rain protection.
In its dimensions the Fastpack 350 is yet surprisingly compact, yet offers enough space for all matters in his inner life, is therefore also suitable for a more extensive equipment.
Clear recommendation!
