Pros: Tons of storage space and well proportioned pocket sizes, 3 liter resevoir and the bite valve are the best I've ever used, obvious attention to detail, looks great

Cons: Padding

Recommendation: I really loved everything about this pack except the padding on the back. It's rubs my back raw (as in bloody) if I don't adjust the straps precisely right. Nobody else seems to have had this problem though so maybe i'm just lucky?

Pros: Love the Nalgene reservoir. This pack fits me great and doesn't feel bulky despite its decent storage capacity. Super high vis.

Cons: The rigid reservoir can be uncomfortable if you don't have the pack adjusted correctly. The sternum strap seems to loosen itself during the ride.

Recommendation: This is a great pack with many features you won't find on those other hydration packs. A magnet to hold the bite valve in place? Brilliant! Good price for a high quality pack that's great for MTB and trail running.
