Way more comfortable, better looking, and holds more stuff, more securely than my old, 1st generation Mule. Also, the vent back feature is outstanding. The expansion capability will be a big factor in the colder months when I shed layers as the day warms.
It might hold too much (is that a bad thing?). I find I am tempted to carry more items than I would have with my old Mule.
Overall, a great hydration pack from the masters, CamelBak. The Blowfish is highly recommended.
