Good for the price
I bought this for car/summer camping where nighttime lows are usually high 50's or low 60's. I figured it couldn't hurt to have a 20 degree bag just in case I needed the extra warmth. Recently experienced mid 30's and i'm glad I brought tons of extra clothes because I needed them in this thing. At 35 degrees, I felt base layers and socks were insufficient to stay warm. A lot of that might have to do with a lack of hood but that was my choice. I hate mummy bags and their constriction.
