Thrush false bottom down sleeping bag

The Thrush is a false bottom sleeping bag. This is a full sleeping bag that wraps all the way around the sleeper, just without the insulation in the bottom where it is compressed and has limited effectiveness in a traditional bag. This design pushes weight savings well below traditional bags and even below quilts, but performs totally draft free like a full sleeping bag. It is important with any sleep system that it is paired with a sleeping pad rated to similar temperatures. It is especially important with quilts and false bottom bags and it should be noted that pads that utilize empty spaces are generally not suitable for these types of sleep systems.

This should be used with a Waterbear hood or can be used with other types of head insulation.

All sleep systems are 20% overstuffed. Combined with vertical split baffles, there is very little down migration. A drawstring footbox that opens up for venting, wearing the system around, etc is optional for no extra charge. It usually adds .5 to 1oz to the finish weight of any given system.
