Ever heard of bivy sacks? They’re a secret weapon for those who want to reduce their gear weight without giving up protection from the elements.
In this post, we’ll cover all you need to know about bivy sacks. Whether you’re a curious explorer or a seasoned adventurer, you’re in the right place.
A bivy sack, which stands for bivouac bag, is a clever piece of outdoor gear that, believe it or not, has been around for centuries but started to gain popularity in the 20th century when soldiers began using them in combat. Essentially, it’s like a lightweight, waterproof cocoon for your sleeping bag.
The term ‘bivouac’ means to camp without a traditional tent or shelter, and that’s precisely what bivy sacks allow you to do. They’re designed for those who want to travel light and don’t mind embracing the open air. On average, an ultralight bivy sack is 30-40% lighter than an ultralight 1-person tent.
However, bivy sacks are not just for extreme mountaineering adventures; many outdoor enthusiasts use them as their primary shelter. If you choose to go this route, remember that they only add about 9 to 18 degrees Fahrenheit of insulation. So, consider using a warmer sleeping bag if needed.

Like any outdoor gear, bivy sacks come with their own set of disadvantages. Understanding these is crucial before deciding if a bivy sack is right for you.
TLDR: Bivy sacks are ultralight and enable you to sleep in tight spots where larger shelters won’t fit. Nonetheless, having a well-defined strategy to deal with condensation and wet weather is essential.

Yes, a bivy bag is designed to be waterproof. These compact shelters are typically constructed with waterproof or water-resistant materials, making them effective at shielding you and your gear from rain, snow, and other moisture in the outdoors. However, it’s essential to note that the level of waterproofing can vary among different bivy bags, so it’s advisable to check the specific product’s specifications and choose one that suits your intended outdoor activities and weather conditions. Proper usage, such as securing the bag’s openings and managing condensation, also plays a role in ensuring its waterproof capabilities.
When choosing between a down or synthetic sleeping bag for bivy camping, it depends on your specific needs. Down sleeping bags offer excellent warmth-to-weight ratios, making them great for cold conditions, but they lose insulation when wet. Synthetic bags, on the other hand, are more water-resistant and maintain insulation when damp, making them suitable for wet or humid conditions. Your choice should align with the expected weather conditions and whether you prioritize warmth and weight or moisture resistance.
