Some of the best cheap bivy sacks for keeping you happy outdoors.
  • REI Minimalist Bivy - REI's in house brand is a reliable go to when you want reasonably price backpacking, camping or hiking gear. The Minimalist bivy is a combination of a nylon upper treated with REI's Elements laminate. The bottom is much tougher taffeta nylon, for maximum protection from whatever you lay the bivy sack on. The face portion is bug proof, and has an impressive 6 zippers to create small gaps for ventilation. It also weighs reasonably little, at 15 ounces, or 430 grams. So while coated nylon is the most waterproof option, it's a good bivy sack for most conditions. It also comes in a longer size.
  • MSR E-Bivy - A cheap, if simple bivy sack from MSR. There's no bug net here, just a simple overlapped opening to keep you from getting rained on. The top of the bag is silnylon, while the bottom is tougher taffeta nylon with a waterproof coating, for more durable protection from the elements. So not entirely waterproof, but good enough for most weather. The whole thing does, however, weigh just 9 ounces or 255 grams, so it's definitely a lightweight bivy sack option.
  • Rab Storm Bivi - The Rab Storm Bivi is a 4 season bivy sack. It's both waterproof and breathable, thanks to the Hyperlite Storm fabric on top and the laminated nylon on the bottom. What stands out here is that the opening is along the top edge of the bivy sack, in a U shape, so that you can close the bivy sack up at night and be completely protected from the weather outside. So a better option for when the weather gets ugly, though you wont be able to see the stars at night. The whole thing weighs 17.2 ounces, or 490 grams.
