How to Choose the Best Camping Bivy Sacks
Weight and Packability
For backpacking and minimalist trips, the weight and packed size of a bivy sack are paramount. Look for models made from lightweight materials like ripstop nylon or polyester. Consider how small it packs down; it should easily fit into your backpack without taking up excessive space.
Waterproofing and Breathability
A bivy's primary function is protection from rain and dew. Check the hydrostatic head rating (HH) for water resistance – higher numbers indicate better waterproofing. Equally important is breathability to prevent condensation buildup inside. Look for bivies with vents or made from waterproof-breathable membranes like Gore-Tex or similar technologies.
Durability and Features
While lightweight is good, durability is crucial for longevity. Inspect the fabric denier and seam sealing. Some bivies offer features like bug netting at the opening, tie-out loops for stability in wind, or a slightly larger design to accommodate a sleeping pad and bag comfortably. Decide which of these extras are essential for your needs.
