If you need to camp in a bivy sack on a multi-night trip that offers no opportunity to dry out your gear during sunny mornings, the Mountain Laurel Designs eVENT Soul Bivy is just about the only bivy sack we recommend. For what it offers – significant condensation resistance (because of the 3L eVENT fabric used on the upper), a durable DCF floor, zippered side entry, noseeum netting option, and a stiffened brim – it’s one of the best all-around bivy sacks on the market.
