Jason is going camping and needs a backpack that will replace the one that he lost last year. He is going on a trip that will last 4 to 5 nights depending on how bad the mosquitos get. It has been raining in the area and the warm weather makes has really added to the number of mosquitos out there. It will likely rain on the trip and he needs to keep his gear as dry as possible. The long hikes mean that he wants to travel light and stay hydrated. The ability to use his hydration bag & tube are important to staying on the trail. The pack should have all the necessary straps to secure the pack, especially because he will be on steep climbs and balance is important. He has a budget of $350 but wants to make the best purchase.
