We've taken a look at extra large cold weather sleeping bags and want to let you know about them.

They are usually designed with a draft collar, keeping warm air in and cold air out. They feature draft tubes, which run the length of the bag behind the zipper to help prevent warm air from escaping. Typically made with feather down, cold weather sleeping bags will compress down easily, while still being providing excellent thermal insulation. They are made from thicker materials than smaller and shorter sleeping bags, so they are very comfy and cozy to sleep in. They are very spacious, designed for taller campers and those that prefer a bit of extra shoulder and leg room.
