Quick Answer
Bivy sacks can be a viable option for couples in the backcountry, but they require careful planning and a willingness to compromise on space and comfort.
Bivy Sack Considerations for Couples
When considering a bivy sack for a couple, it’s essential to prioritize space and comfort. Look for a model with a width of at least 60 inches (152 cm) and a length of 80-90 inches (203-229 cm) to accommodate two people comfortably. Models with a rectangular shape and a full-length zipper can provide more usable space than traditional, tapered designs.
Emergency Space and Shelter
In a survival scenario, every inch of space counts. Bivy sacks can be used to provide a windbreak and some degree of rain protection, but they typically don’t offer enough room for both partners to sit up or move around comfortably. To mitigate this, consider using a space blanket or emergency bivvy sack as a supplementary layer, rather than relying solely on the bivy sack. This can help maintain body heat and provide additional protection from the elements.
Shelter and Sleeping Bag Considerations
When using a bivy sack in conjunction with a sleeping bag, make sure the two are compatible in terms of temperature rating and design. Look for a sleeping bag with a temperature rating that matches the expected low temperature in the area, and consider a model with a built-in bug net or mesh panel to improve ventilation. In a survival scenario, it’s also crucial to have a reliable shelter, such as a tent or tarp, as a backup option in case the bivy sack becomes wet or compromised.
