E-Bivy

Effective at repelling outside moisture while you slumber soundly under the stars, the MSR E-Bivy offers solid protection from damp ground surfaces and morning condensation, all without burdening your pack with excess weight and bulk. In fact, the E-Bivy tips the scales at a scant six ounces, packing down to the size of a soda can (7 x 4-inches) for minimalist carrying on ultra-light backpacking missions, long-distance bike tours, and even alpine expeditions where an emergency shelter offers extra peace of mind.
