I need some suggestions on a new backpack, and was hoping that the wonderful tipb forum members could help me. I need a new backpack for carrying on a plane and also taking to an amusement park or something like that. So I was looking for whats the most comfortable straps, back ventilation since I will be carrying it for hours in the hot sun some days. But I also want to use it to carry on the plan and hold my gadgets. Laptop, phone, water, etc. For awhile I was looking for a backpack with a small slot for my canon digital rebel, but most photo backpacks are for more advanced people then me that have several lens. So I decided to just use my small camera pouch inside a nice comfortable backpack that has a good storage, lightweight, good back ventilation, etc. Your suggestions are always greatly appreciated.
