Discounts (USD):



This is a frameless 40L + 16L (side pocket) capacity pack that is designed so you should place a closed cell mattress at your back to give the pack structure. (e.g. Thermarest Z-lite Sol or cheaper Naturehike equivalent)


Pros
  • Excellent affordable entry level pack
  • Solidly built with thick shoulder straps and thick hip belt 
  • 3 colours (blue, grey, orange)
  • Lightweight at 950 grams, can cut weight further by removing surplus straps
  • Large volume, with generous side pockets
  • Mesh front pocket
  • Roll top closure

Cons
  • Somewhat heavy for a frameless pack
  • Not very water resistant
  • Only one back length (6" height OK)
  • Rigid hip belt - uncomfortable if not using sleeping mat as frame
