Introducing the Zenbivy Pack Liner

Simplify your packing process. The Zenbivy Pack Liner is a fully waterproof, easy-to-compress dry sack that holds all your sleep gear in one compact layer at the base of your pack—saving time, maximizing space, and eliminating frustration.

It's the Better Way to Pack

  1. Multiple dry sacks waste time and space.
  2. Oversized liners are awkward and hard to compress.
  3. Trash bags? Not reliably waterproof.

The Zenbivy Pack Liner solves all of those problems. Pack your gear like a traditional dry sack—outside your pack, in the comfort of your tent—compress it with the high-speed valve, and slide it straight into the bottom of your backpack. Hike easy knowing your sleep essentials will remain dry.

Shaped to Fit Your Pack Perfectly

The Zenbivy Pack Liner completely fills out the bottom portion of your pack—eliminating dead space and giving you a solid foundation to pack the rest of your gear on top of.

Keep it simple. Pack all of your sleep gear—quilt, sheet, mattress, pillow, clothes, and anything else you want to keep dry until you reach camp—in one easily compressible, waterproof bag.

What Size Pack Liner Do You Need?

Use a flexible tape measure to wrap around the outside of your pack a few inches above the base—typically just above the hipbelt or taper. Make sure exterior pockets are flattened and straps or cords are out of the way for an accurate measurement. It can be easier to pre-stuff the pack and measure the outside of your pack, or you can measure the inside of an empty pack.
