These guys make good stuff. I don't have any of it, but know a number of people who do and are very happy with their acquisitions. Not too heavy, but durable/functional. I went to the company home page; read about what they considered in the design of the pack. Sounds like they did their homework to me. Problem is I would want to see the pack in person before I fully committed. Check out the return policy or contact them to find the nearest rep.
