People make fun of Slankets and Snuggies and that great Canadian invention, the Thuggie, but in fact, these things make a lot of environmental sense, as Insulating Your Body Is Cheaper And More Effective Than Insulating Your Home. Now there is a new, hipper kid on the block that can be used inside or out: the Napsack. It is a cross between a sleeping bag and a Snuggie.
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.
It is certainly more stylish than the usual slanket; I love how the model has Eames chairs in the kitchen, a classic Acorn fireplace and midcentury modern coffee table in the living room; Slanket and Snuggie people are always on big leather sofas watching big screen televisions.
Kris De Decker wrote in Low Tech Magazine about the importance of clothing as part of an energy saving strategy:
The energy savings potential of clothing is so large that it cannot be ignored - though in fact this is exactly what is happening now. This does not mean that home insulation and efficient heating systems should not be encouraged. All three paths should be pursued, but improving clothing insulation is obviously the cheapest, easiest and fastest way.
The Napsack is rated to 50 degrees F; Imagine the energy savings if you kept your thermostat set at 50 all winter and wore wore this around the house. Available at POLER.
