Rab Alpine Bivy

When you're planning on sleeping in tough conditions but aren't interested in carrying a tent, stick the Rab Alpine Bivy in your pack. It weighs only a pound and packs down to the size of a water bottle, so you'll never have to leave essential gear out of your pack to bring it along, and it zips up all the way to offer full protection from the alpine elements. The eVent 3L waterproof and breathable membrane keeps water out and prevents condensation from building up inside, and the tough nylon floor stands up to rough ground when you're sleeping in less than perfect conditions, so you won't wake up with your butt in the snow.
