MSR E-Bivy

Jump to: Our Verdict / Features / Specifications

This ultralight emergency bivy sack offers the ideal amount of protection for wide range of situations without adding much to your pack—making it the perfect backup shelter.

MSR says:

The diminutive, ultralight and weather-resistant E-Bivy sack can be tossed into a pack lid on any trip, providing essential protection for an unplanned night in the hills, or added warmth and comfort when used under tarps or on open bivies. Its silicone-coated fabric top blocks wind, dew, spindrift and precipitation, making it the perfect emergency shelter.

Our Verdict

MSR’s E-Bivy is MSR’s lightest and most compact, water resistant bivy, now 25% lighter than the previous version. It does exactly what a good bivy should; it offers protection from wind, damp ground surfaces and morning condensation, all without burdening your pack with excess weight. The pack size is excellent too, packing  smaller than a Nalgene bottle so it doesn’t take up valuable room in your pack.

If you’re looking for a minimalist camping shelter you can combine it with a tarp and lightweight sleeping bag to provide a warm and dry nights sleep. It can also be tossed into a pack lid on any trip, providing essential protection for an unplanned night in the hills.
