On warm summer weekends, we spend our nights at car-accessed campsites cuddled up in the Catena Sleeping Bag. This cozy, synthetic-stuffed bag offers us the warmth and weight we need to get a good night's rest when we use the earth as our mattress. Its rectangular shape lets us stretch and adjust in ways a mummy bag won't, and its full-zip design easily transforms into a blanket when we need more room or a little fresh air.
