It is similar and lighter. So far with my test runs I am pleased. Carrys very well. I almost popped on a bLaze last year. I am glad i didnt I think it may be a bit more than I need? Looks to be a great pack though, Frankly, When I wanted a Blaze I could not find one in stock. I found my crown vc and jumped. Now I am glad i did! I will give a better reveiw in 3 weeks on return from the AT.
