Sleeping Bags Have Flex Panels?--Flash Sale

Who knew?  Apparently sleeping bag design has now incorporated flexible portions to move with you during the night.  I'd like to replace my bag soon.  If you're also in the market, check out The Clymb's current flash sales on Sierra Designs.  Other current lines include Kastle skis, Bolle helmets, Spot Brand bikes, Schwalbe cycling tires, Easton snowshoes, and more.
