The Napsack has zippers at the shoulders, so you can stick your arms out, and a cinch at the bottom so that you can open it up and stick your legs out. Hike it up to your waist, cinch it, and wear it like a puffy coat around the campfire, and then crawl right back into your tent without ever having to leave the warmth of your bag.
