|I purchased this backpack in October 2008, not for "field use" but for everyday use. I'm a diabetic and a techie so I have to carry a lot of tools and accessories around for both my health and my work. I wanted a one shoulder back pack with the capability of carrying both a laptop and a hydration system, that had enough internal pouches to hold all my medical supplies and simple hand tools.
I've now owned this backpack for nearly 4 years, and I've used it almost daily since then. It's been through freezing winters, and hot humid summers, traveled to Mexico and Canada and has been through 8 airports. I wear it while riding my scooter to and from work and other locales. I carry diabetic blood sugar monitoring tools, insulin, medicine bottles, glucose bottles, laptops, hydration systems, tools, notebooks, tablets, phones, shoes, books... I've packed it pretty heavy. I've even had occasion to utilize the MOLLE system with several different MOLLE pouches attached to carry even more.
Through nearly 4 years of abuse, it's never failed me. All the zippers still work perfectly, all the clasps still work perfectly. I can still see several more years of use before I would want to replace it. I think it would likely last me a full decade.
Well worth the relatively low price.|
