Lose inches with a single easy cinch. Compression sacks are great for reducing the volume of sleeping bags and insulated clothing, but most require tightening multiple straps. The Z Ultralight uses a pulley system to let you pull a single cord and give you a three-to-one mechanical advantage for easier, more complete compression.
- Fabric is not waterproof, but will protect against light showers
 - Bound seams on end for durability
 - Stuff pocket holds excess cord when the bag is compressed
 - Built-in bottom stuff sack stores compression bag when not in use
