With over 30 bags to choose from we have made it easier for you to choose the best fitting bag. Start by judging your body size, or what kind of room you need to stay comfortable throughout the night.

Our wide cut semi-rectangular bags are named after North American Forest Trees. This is the choice for people needing lots of room regardless of weight. Some of these bags have hoods. Our wide cut mummy bags run 62" to 66" in shoulder girth and are named after North American Mammals. This is the standard cut bag for most lightweight mountaineering.

We also have a series of narrow cut mummy bags and they are named after our North American Indian Tribes and Nations. These bags provide the most savings in weight and are the most temperature efficient. They are also a more compressible package to carry around.

Our EXTREMELITE bags are easily identified by the suffix "LITE". These are the lightest weight bags available and are meant for those activities when extreme compressibility and weight are an issue.
