Pack Smarter, Not Harder

Instead of juggling multiple dry sacks, struggling with oversized liners, or using unreliable trash bags, the Zenbivy Pack Liner keeps it simple.

Pack and compress your gear like you would in a traditional dry sack—outside your pack, in the comfort of your tent.

Slides Right Into Your Pack

Once stuffed, compress it down with the high-speed valve for a tight, compact fit. Then slide the liner straight into the bottom of your backpack.

Create a Stable Foundation

The final step: push the Pack Liner full of gear into the bottom of your backpack to compress it again and completely fill out every corner, maximizing space and creating a solid foundation to stack the rest of your gear on top of.

Your Pack Is Shaped—Your Liner Should Be Too

Zenbivy Pack Liners fit your pack’s shape. Others don’t. That means no wasted space—just a cleaner, more efficient pack.

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.

36" or under? Medium
Over 36" diameter? Large
