Your Guide to Choosing the Best Bivvy Bag
When you need to sleep outdoors with minimal gear, a bivvy bag is your best friend. It’s a lightweight, waterproof cover that goes over your sleeping bag. Think of it as a one-person tent, but much smaller and simpler. This guide will help you pick the perfect bivvy bag for your adventures.
Key Features to Look For
When you’re shopping for a bivvy bag, keep these important features in mind:
- Waterproofness: This is the most crucial feature. You want a bivvy bag that keeps you dry. Look for a high waterproof rating (measured in millimeters, like 10,000mm or more).
- Breathability: A bivvy bag needs to let moisture escape. If it traps too much sweat, you’ll end up damp and cold. Look for a “breathable” rating or features like vents.
- Weight and Packability: You’ll be carrying this, so lighter is better. A good bivvy bag should be easy to fold up small and fit into your backpack.
- Durability: You don’t want your bivvy bag to rip on your first trip. Strong materials and good stitching make it last longer.
- Ease of Use: Some bivvy bags are simple to get into and out of. Others might have zippers or drawstrings that can be a bit tricky.
- Size and Fit: Make sure it’s long enough for you and your sleeping bag. Some bivvy bags have extra room for gear.
Important Materials
The materials used in a bivvy bag greatly affect its performance.
- Outer Shell: Most bivvy bags use nylon or polyester. These fabrics are strong and can be made waterproof. Ripstop versions have a special weave that stops small tears from getting bigger.
- Waterproof/Breathable Membranes: Many high-quality bivvy bags use special coatings or membranes. These stop water from coming in but let sweat vapor out. Gore-Tex is a well-known example, but there are other good options.
- Zippers and Closures: Waterproof zippers are important. Drawstrings or elastic closures at the openings help seal out the elements.
Factors That Improve or Reduce Quality
Several things can make a bivvy bag better or worse.
- Sealed Seams: All the seams on the bivvy bag should be taped or sealed. This prevents water from leaking through the stitching.
- Ventilation: Good ventilation is key. Look for mesh vents or roll-back openings that let air flow without letting rain in.
- Reinforced Areas: Areas that get a lot of wear, like the foot or elbow sections, might have extra reinforcement. This makes them more durable.
- Simple Design: While some bivvy bags have poles or complex shapes, simpler designs are often lighter and easier to set up.
- Cheap Materials: Using very thin or non-breathable fabrics will lower the quality. Poorly sealed seams are also a sign of lower quality.
User Experience and Use Cases
A bivvy bag is perfect for many outdoor activities.
- Backpacking: When every ounce counts, a bivvy bag is much lighter than a tent.
- Ultralight Camping: For those who want to travel with the absolute minimum gear.
- Emergency Shelter: It’s a great backup to have in your pack in case of unexpected weather.
- Bikepacking: Its small size makes it ideal for bike tours.
- Fastpacking: Combining running and camping often calls for ultralight gear.
Using a bivvy bag is straightforward. You lay it out, put your sleeping bag inside, and then get in. You can zip it up completely for maximum protection or leave an opening for airflow. It’s best used in fair weather or when you need a very light shelter. In heavy rain or strong winds, a tent might offer more comfort and space.
