Backpacks: When selecting a backpack, decide which type you are in the market for. Do you need simple bags to carry snacks, special outdoor gear for backpacking or hydration packs for hiking? Backpackers should look for a large enough backpack to carry all of their outdoor camping equipment. Remember that the more outdoor gear you can fit into your backpack, the heavier it will be. Frames should be comfortable around your hip bones. Many backpacks will have a frame-sheet across the back. A good backpack should remain flexible and transfer weight effectively. A quality back panel will alleviate the discomfort associated with a sweaty back. Some panels have grooves for air flow, while others have reticulated foam.
