The size of your sleeping bag directly determines its thermal performance. Too big, and your body has to heat excess air and loses efficiency. Too small, and the down gets compressed at the feet and hood, exactly where it needs its loft to insulate.
A bag fitted to your height eliminates this dead space without crushing the fill. It also lets you keep cold-sensitive items close to your body: batteries, water bottle, gas canisters… which lose capacity or may freeze during the night.
