Crafting an Ultra-Light Bivy Sack for Less Than a Dollar

The Quest for an Affordable Bivy Sack

Bivy sacks, short for bivouac sacks, are minimalist shelters for backpackers who prioritize weight and simplicity. While commercial bivy sacks can cost upwards of $200, there's a frugal and lightweight alternative for the budget-conscious adventurer.

The High Cost of Commercial Bivy Sacks

Commercial bivy sacks are known for their compact size and ability to protect against the elements. However, they can also feel restrictive and come with a hefty price tag. For those looking to save money and reduce pack weight, there's a creative solution that doesn't compromise on functionality.

A DIY Approach to Bivy Sacks

After purchasing a $20 emergency bivy and experiencing a surprisingly dry night under the stars, I realized that a bivy sack is essentially a large, durable plastic bag. This epiphany led me to create my own bivy sack using two extra-large garbage bags and some duct tape. By cutting open one end and sealing the rest, I crafted a three-foot by seven-foot bivy sack that weighed a mere four ounces.

Comparing Weights and Costs

| Item | Weight | Cost | |---------------------|----------|---------| | Commercial Bivy | Varies | ~$200 | | Emergency Bivy | 8 ounces | $20 | | DIY Garbage Bag Bivy| 4 ounces | <$1 |

The Advantages of a Homemade Bivy Sack

• Weight: At just four ounces, the homemade bivy sack is significantly lighter than even the lightest commercial options.
• Cost: For less than a dollar each, these DIY bivy sacks are incredibly cost-effective, especially since they can last for a week of nights with careful use.
• Disposability: Given their low cost, these bivy sacks can be disposed of after a trip, eliminating the need for maintenance and storage.

Using Your DIY Bivy Sack

While the homemade bivy sack is not without its drawbacks—such as potential dampness in the morning—it's well-suited for dry environments and can be a viable option in more humid climates with some adjustments. It's important to dry out your sleeping bag during breaks, taking advantage of the sun's warmth to remove any residual moisture.

Tips for a Comfortable Experience

• Ventilation: To minimize condensation, ensure proper ventilation by keeping your head outside the sack or using a small umbrella for shelter.
• Care: Handle your DIY bivy sack gently to extend its usability beyond a single trip.
• Drying: Lay your sleeping bag out to dry whenever possible to maintain comfort and warmth.
