**NOTE:** Product's length is 'Long Length' Marmot sleeping bags are world renowned for their quality and comfort. The NanoWave 45 is a perfect bag for when temperatures will not drop below 55 degrees. In Colorado’s high country​,​ that’s pretty much never. However​,​ most of the Eastern Seaboard of the United States has 3 or more months when average lows are 60 degrees or above. And​,​ it’s a great bag for indoor applications because it doesn’t have all that extra insulation. GEEKTIP: Remember how I said this bag may not be warm enough in Colorado’s high country​,​ well I use it all the time there. Long underwear buys me about 10 degrees and if its going to be a bit colder I will add a sleeping bag liner sheet to buy me another 5 degrees. This bag is so light weight and tiny at 8″x 8″x 6″ it’s size makes it practically irresistible to me.
