When my SO began backpacking last year, we elected…

Rating: rated 3 of 5 stars
Design: Semi-rectangular
Fill: synthetic
Temperature Rating: 20 F
Price Paid: ~$120

When my SO began backpacking last year, we elected not to purchase a sleeping bag for her. Instead we went with the Cascade Designs Therm-A-Nest system.

Basically, the system consists of a big pouch that holds two Therm-A Rest mattresses side by side onto which zips an opened up Cascade Designs sleeping bag.

The system is compatible with a number of Therm-A-Rest pads (we use a full-length and 3/4 length pad) and a number of different sleeping bags. We purchased a semi-rectangular bag that is rated to +20F. We actually used it on a 5F trip, although we needed a wool liner blanket to stay warm. We've since purchased the 0 F bag which we'll try this winter. The pouch contains no insulation so the only insulation under you is afforded by the mattresses.

It is not a cheap system when you add up the cost of the two pads (but we already had them and would have needed them anyway), the pouch and the compatible sleeping bag. But, it does have a couple of advantages. One is the obvious advantage of sharing a single sleeping bag. The other is that we only need carry one bag between the two of us. Saves weight overall.

I'd be interested in the experiences of anyone else who has tried this system.
