Pros & Cons

Update Pros and Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

Works well to keep you comfortable on a backpacking or bikepacking trip on warm nights. Never seem to get all tangled up in it if i shift my position while sleeping.

Competitiveness

I use an r7 rated sleep pad from costco with the bag and this liner.
