Critter Potato Sack: The Ultimate Warmth Boost
Elevate your sleep system with the Critter Potato Sack, the ultralight secret weapon for a warmer, cleaner, and more comfortable night outdoors. This sleeping liner uses the advanced Polartec® Alpha Direct fabric, known for its active insulation and incredible performance.
The unique lofted fiber construction delivers an impressive thermal boost while remaining ridiculously lightweight and highly compressible, packing down easily into your backpack. Unlike traditional liners, Alpha Direct is exceptionally breathable, regulating your temperature so you don't overheat or feel clammy as you sleep. It actively manages moisture, is fast-drying, and feels soft and cozy against your skin. It’s more than just a liner—it protects your sleeping bag from dirt and body oils, extending its loft and lifespan.
On warmer nights, the liner can even function as a standalone ultralight blanket or summer sleeping bag, making it a truly versatile piece of gear for any trip.
The regular size is 29"x72" and fits someone up to 5' 10".
The regular size is 29"x81" and fits someone taller than 5' 10".
The foot is 22" wide for both sizes.
