Learn how to attach, remove, and configure the fleece liner on the Polara 3-in-1 sleeping bag for optimal warmth across seasons. Step-by-step instructions included.
Quick Answer
Attach the fleece liner to the Polara 3-in-1 sleeping bag using the two-way zippers and Velcro tabs. You can combine or separate the layers to create seven temperature configurations from 60°F down to -10°F.
Why the Fleece Liner Matters
The Polara 3-in-1 sleeping bag is designed for year-round use. The fleece liner is the key to that versatility—it adds warmth in cold weather and can be removed for milder nights. Without understanding how to attach and detach it properly, you risk cold spots or a bag that's too warm.
The liner attaches with no-snag two-way zippers and secure Velcro tabs, so it's easy to switch configurations even in the dark. Knowing the right setup for your conditions makes the difference between a comfortable sleep and a restless one.
How to Use the Fleece Liner: Step-by-Step
- Unzip the main bag completely: Lay the Polara sleeping bag flat on a clean surface. Unzip the main outer bag's full-length zipper so both layers are fully open and accessible. Common mistake: Trying to attach the liner while the bag is partially zipped can cause the fabric to twist and the zippers to jam.
- Align the fleece liner with the outer bag: Spread the fleece liner on top of the outer bag, matching the foot end and the zipper tracks. The liner's zipper should run parallel to the outer bag's zipper. Check that the Velcro tabs on the liner and outer bag are facing each other before zipping.
- Zip the liner into the outer bag: Starting at the foot end, engage the liner's zipper with the outer bag's zipper track. Pull the zipper slowly upward, keeping the fabric flat. Secure the Velcro tabs at the top to prevent the liner from shifting. If the zipper snags, back up slightly and smooth the fabric. Never force it—this can damage the teeth.
- Choose your temperature configuration: For warm weather (60°F), use the fleece liner alone. For mild conditions (30°F–40°F), use the outer bag without the liner. For cold weather (0°F and below), zip the liner inside the outer bag. You can also use the liner as a standalone blanket or sleeping bag. The Polara offers seven total configurations. Test the setup at home before your trip to know which combination works for your comfort level.
- Remove and store the liner: To detach, unzip the liner from the outer bag and release the Velcro tabs. Fold the liner separately or stuff it into the included compression sack. Store both layers in a dry place away from direct sunlight. Never store the liner compressed for long periods—this can reduce its loft and insulating ability. Use a large cotton storage sack instead.
