Poler Napsack Sleeping Bag BlueThe 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.FITS UP TO 5’8" to view our entire selection of Poler products
