Description:

The Zero is built just like the other backpacks except that it has zero pockets.

• Use the smaller sizes as a food bag, or sleeping bag stuff sack that you can also carry on day hikes and peak bagging. You can compress the pack to any height with the draw cord - loop closure system.
   
• Add pockets below, or any of the standard Backpack Options to create a full featured pack.
   
• Available in 1.5 oz/sqyd Cuben Fiber or 1.3 oz/sqyd Sil-Nylon. Either version weighs about the same. Cuben is about twice as durable but either is fine for normal use.
  
  Note that the sil-nylon version weighs less than the equivalent sil-nylon packs (Zilch, Z1) because it does not have a black 2.4 oz/sqyd nylon base or side pockets.
   
• Size small folds up tiny enough to fit in a Ziploc bag as shown.
   
• 1 year warranty against defects in materials or workmanship.
