MSR AC Bivy

All-condition bivy protection with maximum breathability.

When weight and space really count, the AC Bivy shelter is the best and most efficient way to get the all-condition protection you need. Maximum waterproof-breathable fabric coverage on top delivers the best possible breathability, while an extra-tough floor with 10,000mm DuraShield^™ coating lets you rest confidently through anything. A zippered shoulder entry with mesh allows excellent bug-free ventilation and makes the bivy shelter easy to get into and use while sitting up.
