A bivy bag is much lighter than a tent and will help you shield your sleeping bag while keeping you comfy and dry. They're especially useful for outdoor camping. Many people, from campers, and hikers to military personnel use these. This is why a military buvy bag is a popular choice. It's not just their camo, but also made of breathable and waterproof fabrics, that will make sleeping outdoors a breeze.
What's a Military Bivy Bag
Bivvy bags are like waterproof shields for your sleeping bag, keeping you cozy and dry while you camp outside. They're a top choice among military folks who prefer them over tents because they’re lightweight, compact, and easy to haul around on hikes and backpacking trips. Plus, a bivy bag is cheaper than a tent and takes up much less space. You can set it up in tight spots where a tent wouldn't fit, making it super convenient. Unlike a tent, which can feel like a cramped indoor space, a military bivy bag lets you connect with the outdoors. You can feel the fresh air, gaze at the stars before drifting off, and wake up to stunning views. It adds a sense of adventure and wildness that you just don't get with a tent.
How to Use It?
To use a bivvy bag, just slide it over your sleeping bag. When you’re ready to sleep, pull it up over your head, but leave a little opening for your mouth to help reduce condensation. You can keep your sleeping mat outside, but if the weather’s really bad or you have a bigger bivvy bag, you can try putting it inside. Don’t forget to bring a big waterproof bag, like a trash bag, to stash your other gear at night. You can use your boots and backpack as a makeshift pillow. Keep in mind that a bivvy bag can be chillier than a tent, so pack some warm clothes.
Types of Bivy Bags
Traditional Bivy Bag
Think of the traditional bivy bag as the classic choice for outdoor adventures. It's built tough with waterproof materials to shield you from the weather. This style usually has a tube shape that wraps around your sleeping bag, leaving just a small opening for your face to stick out.
Hooped Bivy Bag:
Now, the hooped bivy bag is like the upgraded version of the classic. It features a lightweight pole that creates a dome shape above your head, giving you extra space and preventing the bag from smothering your face. Imagine it as your own little outdoor lounge, where your sleeping bag is the main attraction!
Ultralight Bivy Bag:
For those hardcore backpackers and hikers, ultralight bivy bags are the way to go. These are crafted from super lightweight materials and are often minimalistic, focusing on just the essentials to keep your pack as light as possible.
Modular Bivy Bags
These bags feature a flexible design that lets you mix and match them with other gear like tarps or mosquito nets, making it easy to set up a full-on shelter system.
Double-Walled Bivy Bags
With a waterproof outer layer and a breathable mesh inner layer, these bivy bags keep you dry while allowing air to flow, reducing the chance of condensation inside.
Emergency Bivy Bags
Built for tough situations, these bags are perfect for hikers or backpackers who find themselves lost or stranded. They’re typically made from super reflective materials, making it easier for rescue teams to spot you.
Bivy Bag Anatomy
Fabric
When it comes to bivy bags, the fabric can differ quite a bit, but you want something that's tough yet breathable. Ripstop nylon is a go-to option, but if you're expecting rain, make sure it has a waterproof coating. Some brands use Gore-Tex or similar waterproof-breathable fabrics, which might cost a bit more but provide fantastic protection.
Zippers
Zippers are crucial for a good bivy bag experience. You’ll want a sturdy zipper that won’t get stuck or break on you. A double-sided zipper is a nice touch, making it super easy to get in and out of your bag.
Poles
If you’re going for a hooped bivy bag, it usually comes with poles to give you some extra headspace. These poles are typically made from lightweight materials like aluminium or carbon fibre. Just ensure they’re strong enough to handle windy weather but light enough for your backpacking trips.
Guy Lines
Guy lines are the ropes that help keep the bivy bag tight and secure, especially for hooped designs. Look for a bivy bag with several attachment points for guy lines, as this will allow you to adapt to various terrains and weather. And if you want to add a little flair, you can even find guy lines in different colours to match your gear.
Things to Consider When Picking a Bivy Bag
Weather and Climate:
A bag that works great for a warm summer night might not cut it when the temperature drops and snow starts falling. Look for bags that offer waterproofing, breathable materials, and solid insulation to keep you cozy and shielded from the elements.
Terrain and Activities
Think about the kind of terrain and activities you’ll be tackling on your trip. If you’re planning to hike a lot with your bivy bag, go for something lightweight and compact that won’t slow you down. But if you’re camping in rocky or uneven areas, a bivy bag with sturdy poles for extra support might be the way to go.
Size and Weight
Aim for bags that are lightweight and compact, yet spacious enough for your body and sleeping gear. Just remember, a bigger bag might feel nicer, but it could also be heavier and trickier to lug around.
