The Backcountry Bed has a firm focus on comfort. The oversized design uses an extra wide quilt-like front that allows you to wrap up warm or vent heat quickly depending on conditions.  

Sierra Designs says:

Sierra Design's Womens Backcountry Bed 20 Down Sleeping Bag uses some innovative and versatile features with an oversized design to give you maximum comfort. The spacious dimensions feel even bigger due to the innovative zipless front which has a wide opening with a blanket style front. This is the main feature as it allows you to wrap it tightly around your shoulders or fold it right back to dump excess heat in milder conditions. There is a small chord across the front of it that helps keep it in place but it can be removed depending on what you need.

The bag also features the self sealing foot vent that has been hugely popular on some of the other sleeping bags from Sierra Designs which again makes it great for keeping comfortable on warmer nights. There is a sleeping pad sleeve on the rear of the bag to help keep your mat in place and increase comfort and ease of use. The range of features combined with the oversized design mean that this isn't the lightest of bags and is more suited to car or base camp use but it is still packable enough for overnight hikes for anyone after the space and added luxury it provides.
