Quick Answer
When choosing a bivy bag for off-grid adventures, prioritize waterproof and breathability features, consider the weight, packability, and durability, and ensure it fits comfortably for extended wear.
Material and Water Resistance
When selecting a bivy bag, prioritize materials that offer a balance between waterproofness and breathability. Look for nylon or polyester fabrics treated with water-resistant coatings like Gore-Tex or eVent. These materials can withstand rain and wind while allowing moisture to escape, preventing condensation buildup inside the bag. A minimum 1,000mm water column rating is a good starting point for water resistance.
Size and Fit
A good-fitting bivy bag is essential for a comfortable and restful night’s sleep. Choose a bag with a generous interior space to accommodate your body, but not so large that it weighs you down. Consider a bivy bag with a torso length of at least 70 inches (178 cm) and a width of 28-30 inches (71-76 cm) to provide ample room for movement. When trying on a bivy bag, ensure you can sit up comfortably with your knees bent at a 90-degree angle.
Additional Features and Accessories
Some bivy bags come with additional features like integrated foot boxes, adjustable hoods, and attachment points for gear. Consider these features when selecting a bivy bag, especially if you plan to use it in extreme weather conditions. For example, an integrated foot box can help keep your feet dry and warm, while an adjustable hood can provide extra protection from wind and rain. Additionally, look for bivy bags with reinforced stitching and durable construction to withstand the rigors of off-grid adventures.
