Dakine Quest 28L Photo Pack
This one is not built for the part-timer. Customizable photo compartment with side and front entry makes the Quest worthy for even the most agro. Waterproof zippers keep unwanted moisture off your gear, while the rain cover can be thrown on if the weather turns.
The Quest is an amazing pack for the price. Pack the laptop, tripod and any other gear all with the security of waterproofed zippers.
