Overview
A car campsite or hunting base camp with two sleepers is where this queen-size bag belongs. It has a polyester shell over SuperLoft Elite fill, a zipper closure and a stuff sack for storage.
The reason to buy is the shared space and the family-friendly size, which suits cold-weather camps where a couple wants one bag. The limitation is the heft and the unclear temperature information, since the listing does not give a plain rating.
Who it's for
Couples and families at a base camp or hunting camp will use the extra width. Hikers who carry their gear, or anyone wanting a tapered mummy shape for warmth, should look elsewhere.
Pros and cons
- Fits two people
- Water resistant shell
- Compression sack included
- Three season use
- Heavy to carry
- Temperature rating unclear
- Warranty limited to original owner
Performance notes
Fill traps air around the sleepers, and a larger volume takes more body heat to warm than a single bag. The rectangular cut allows movement but loses heat at the edges. A water-resistant shell sheds light moisture but is not a substitute for a tent.
