Mountainsmith Cascade

Pros:

• Sturdy construction.
• Water resistant.
• Two Nalgenes fit in each side pocket.
• Front pocket converts to day pack.
• Zipper down the front makes stuff in the bottom accessible.
• Very comfortable.
• Lots of space (perhaps too much).
• Hydration compatible.

Cons:

• The buckles that secure the lid connect to the bottom of the back panel instead straight down which makes it awkward. Easily fixed with scissors and a needle.
• The lid hangs awkwardly of the front when the pack is not full.
• If you unzip the lid pocket while the pack is leaned against a tree, everything falls out.
