Which of Our Sleeping Bag Liners is Right for You?

We just launched our long-anticipated sleeping bag liners for 2026 and we're here to help you find the right one for your next adventure. Whether your next adventure is in your backyard or on two wheels in the middle of the desert, we've got a liner for you. 

The UL Recovery Sleeping Bag Liner

Want to feel rested and wake up with fresh legs ready to hop back on the bike or crush the miles you have planned for you next day? Try out our UL Recovery Liner. It's made with integrated CELLIANT® technology, which helps you sleep longer, and better, while supporting faster muscle recovery. 

The UL Recovery Sleeping Bag Liner has been an employee favorite in the field. It's been tested in our local Colorado mountains and used to recover after long days on the Kokopelli Trail. The best part of the UL Recovery Sleeping Bag Liner is that it's only 11.5 ounces or 12 ounces, depending on the size. We think it's totally worth the extra ounces. 

Alpha Direct Fleece Sleeping Bag Liner

Looking for even sweeter dreams in the backcountry? Or an extra layer on a long travel day? The Alpha Direct Liner has you covered. This fleece liner adds 5-10 degrees of warmth and cozy comfort to your sleep setup while also protecting your sleeping bag from dirt and oils after long days on the trail. The Polartec® Alpha™ Direct fabric is lightweight, breathable, and highly compressible, making it easy to pack for travel or toss into your backpack for your next adventure.

Cotton Sleeping Bag Liner

The cotton liner has always been a best seller and for a good reason. This is the most versatile liner we make. Crafted from a cotton and polyester blend, it's ready for just about anything and deserves a spot in your backpack or travel bag. 

Here are some of our favorite ways we like to use the Cotton Liner: 

• Creating a cozy barrier that keeps our sleeping bags clean and oil-free to minimize washes while also adding a bit of warmth 
• Bringing to hostels or when renting a sleeping bag
• Staying warm and comfortable during long flights when cabin temperatures drop 
• Packing for warm camping nights when you only need a minimal layer 

From rugged trail days to long travel nights, our sleeping bag liners are built to meet you wherever your adventures take you. Choose the one that fits your trip and your sleep goals for a restful night.
