Lost Ranger 3N1 0°

The 3-in-1 setup is genius — I used just the outer bag on a mild night and zipped both together when it dropped below freezing. Took me a minute to figure out how the layers attach, but once I did it was seriously warm.

Took this on a 30-degree night and stayed warm with just the outer bag, then zipped both together for a colder trip and it worked great. Having three configurations in one bag means I don't need to own two separate sleeping bags anymore.
