Crevasse rescue kit with the Altitude harness. These are generally the pure basics I take with me.
Ski traverses are where the Altitude shines. Lightweight, uber-packable, and you can put it on without taking anything off.

And of course the pack size, but terrible photo. The harness is much smaller than a Nalgene, and when squished it fills maybe 380 milliliters of space.
