I have tried many many back packs and bags. Recently, I found Vanquest and liked them so much I became a dealer for them. I know that’s a weird thing. I am not trying to say buy a bag from me but check out their bags. They are durable and easy to open. I tried 5-11, maxpeditions, and a few others. Vanquest stuck out to me online and even better in person. Thanks Josh http://www.redlineprep.net
