Lost Ranger 3N1 15°

Took this out for a crisp fall night and the modular setup meant I could shed the outer layer once temps rose around midnight. Switching between the three configurations mid-sleep was way easier than I expected, and the whole thing packed down small enough to fit my pack without a fight.

Woke up at 3am to check the temperature—32 degrees—and I was honestly toasty, the dual-layer setup really earns its name. Swapping between the three configurations is intuitive and takes under a minute, which I appreciate when I'm half-asleep. This is the most versatile bag I've owned.

I slept through a 28-degree night without waking once, and the fact that I could unzip the outer layer and use just the inner bag the next night made the whole trip feel effortless. The three-in-one setup means I don't have to own three separate bags for different seasons.
