I've been using this pack for about 4 to 6 months now. It is a very versatile bag. The longest ride I've used it in has been about 3.5 hours long and its never been a burden to carry it even with the full 3 litters of water. I use it when on long rides for the water and spare parts needed and also when commuting to work to carry a spare change of clothes. I like the zippered compartement on the outside where it has a keychain holder. I keep a key ring with quick-release there for my lock key. Also keep my train tokes there. Very practical. The padding is very good and makes the weight a non-issue. The smaller compartment is very usefull for all your small things like patch, CO2 cartridge, cell phone, etc. The big compartment I haven't used other than for clothing and carrying files to and from work. The side net-pockets are almost useless. I have dropped many things from them as the drawstring has no way of staying drawn. I expexted ventilation to be better. The little ad says the cushion creates a "channel" for air to ventilate your back. Truth is witht the weight of the water and everything you are carrying there is no such channel and your back will no doubt sweat. Good part is that if you carry cold water at least at the begining your back will be cool. All in all I like this bag and would buy it again.

No zippered pockets inside or out to secure small items. Could use more reflective material. Chest strap too short for big guys/layered clothing in winter. Expensive.

A capacious pack that can easily handle your water, a change of clothes, a binder, day and night shades, pen, pump, patch kit, chain oil, keys, and your supper! I work long overnight shifts, so this is critical. Of course, this thing''s heavy... Very comfortable on the back, with only fair ventilation.
