Slightly heavier than some of our other bivi's but the second lightest to use eVent fabric. eVent fabric is very durable and ideal for protecting your sleeping bag in damp environments.

The design is pretty simple as there's no zips at all which means you will have to do a little more squirming to get inside with your sleeping bag. But again, not using zips does save on weight. It has drawcords on either side of the head hole to tighten once in and there's an overlapping hood to cover your head. This provides unrestricted ventilation as the bag cannot fully close.
