An ultralight sleeping system - consisting of an ultralight down mummy-style sleeping bag, down pants, and down jacket - is a core component of an ultralight backpacking gear kit, and it requires careful planning so the components are coordinated with each other and appropriate for the expected conditions. Such a system minimizes weight while providing maximum warmth and versatility without compromising safety or comfort.

There are definitely a lot more of these jackets around since our last review of lightweight down jackets in 2005. And they differ across a broad scale, ranging from minimalist jackets with a very high loft to weight ratio to multi-purpose jackets that balance light weight, warmth, and utility. This article on ultralight down jackets (in three parts) is the last of three coordinated articles covering the insulated components of an ultralight three-season sleeping system capable of handling colder temperatures.
