On amazon I have found a S.O.L emergency bivy. It says it’s reusable. I have a Sierra Design omega double wall tent and planning on a klymit insulated static v pad. My question is how much can I cheat with a low end sleeping bag. Planning on late season rifle hunts due to work restrictions. Just starting to buy collect and use gear. Going to do late season MN backpacking trips b4 heading out west so have plenty of time for failures just wondering where to get a start. Would rather spend money for pack, boots and clothes but looking to save/cheat on other gear.
