Sierra Designs' Ultralight sleeping bag series consists of six bags with a similar design. Four are 800-fill down insulated and two are insulated with Primaloft Sport. These bags have an essential feature set, yet are made as light as possible with 20-denier fabrics, a small jacket-style hood, and a half-zipper. The Flash is the warmest of the four down bags. It's rated by the maker at 0 F, yet weighs only 2 pounds 12 ounces in size Regular. It's also a good value for a zero degree bag at $390. How well does the Flash perform as a winter sleeping bag, and is it suitable for milder conditions?
