Overview

Layering two bags is the idea behind the Lost Ranger: a roomy rectangular outer bag that locks to the pad and a hooded inner bag made for side sleepers. Use one alone on mild nights and both together when it turns cold.

One purchase covers several seasons, since the outer bag, the inner bag and the combined pair each suit different temperatures. Without a stated temperature rating, buyers cannot match it to a forecast.

Who it's for

Backpackers and campers who sleep in mixed seasons and like to roll around at night. Those heading into hard cold need a bag with a clear rating.

Pros and cons

Pros
  • Three sleep setups in one
  • Inner bag suits side sleepers
  • Pad sleeve stops rolling off
  • Two-way zippers for venting
Cons
  • Temperature rating not listed
  • Pad sold separately
  • Height limit figure looks low

Performance notes

Layering the inner bag inside the outer adds loft, and offset quilting lines prevent cold spots where stitching would compress down. The base is a pad sleeve, so ground warmth depends on the pad you pair it with.
