Thrush false bottom 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. Venting is accomplished with the top drawcord and/or with the optional bottom drawcord at the footbox. It is possible to build with a bottom zip upon request. This design pushes weight savings well below traditional bags and even below quilts, but performs totally draft free like a full sleeping bag. The drawcords provide plenty of venting for most people without the weight, bulk, and complication of zippers but it should be noted thatone can be installed, initially or post sale. 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 balaclava or can be used with other types of head insulation.
This can be paired with a Merganser overbag that clip together with it

All sleep systems are 80% overstuffed over the baffle height for dense chambers. Combined with vertical split baffles, there is very little down migration.
