Sierra Designs Lullaby

Honestly, I had to get this bag because it was green and it was Sierra Designs. Fortunately, it performed well beyond its green qualities. My favorite part of this bag is the fleece chin guard! I've used this bag in temps below 35 with a microfleece liner and the performance was superb. It's a great summer and spring bag, and when I get too warm, I just unzip at the foot and let my feet out. The stretch feature allows a few extra inches to sprawl out in, but not so much that you get cold spots. Great green bag!
