User Review: Sierra Designs Lite 'n Up
Fill: synthetic polarguard?
Temperature Rating: 20 F
Weight: ~4 lbs.
Price Paid: $160
The list price is about $160, I got it for $110 on sale. Very warm, nice loft. I especially liked the fabric that it was made of. It wasn't the itchy or really rough nylon, but it felt almost like silk. I enjoyed sleeping in it.
