Review on 🌧️ Grizzly Gear Weatherproof Lite Reflective by Jason Rodman

I used a mylar bag as a mid layer over my regular sleeping bag (an old sleeping bag that might not be rated for very cold weather) and under a fleece outer sleeping bag. Warm and cozy all night in 30 degree weather. During the day I had to turn my sleeping bag and Mylar bag inside out to dry. I didn't notice any moisture while I slept. Just a bit annoying having to redo the 3-layer setup every day after drying. but it was worth it, because I was warm at night.
