What You'll Learn
Sleeping mats inside or outside?
Sleeping mats can be placed either inside or outside a bivvy bag, depending on various factors. Some people prefer to keep their sleeping mats inside the bivvy bag for protection and to prevent themselves from rolling off the mat during the night. Additionally, placing the mat inside can be more comfortable, especially if you have an inflatable mat, as it keeps the mat dry and clean.
However, others argue that putting the sleeping mat inside can cause the bivvy bag to wear out quickly and take up valuable space. Inflatable mats can also be challenging to fit inside the bivvy bag, leading to a tight and uncomfortable sleeping arrangement.
When using an emergency foil-type bivvy bag, it is generally recommended to place the sleeping mat outside. This is because these bags are primarily designed to be waterproof and breathable rather than spacious. By placing the mat outside, you can also turn over more freely and have extra space to sit up in the morning.
Some people also choose to place their sleeping mats outside the bivvy bag to protect the bag from getting muddy or damaged by sharp objects on the ground. This can be especially important if you plan to sleep without a tarp, as it helps to keep your bivvy bag clean and dry.
Ultimately, the decision of whether to place your sleeping mat inside or outside your bivvy bag depends on your personal preferences, the type of bivvy bag and sleeping mat you have, and the specific circumstances of your camping trip.

Bivvy bags vs. tents
Bivvy bags are a minimalist alternative to tents. They are lightweight, waterproof bags made from fabric such as nylon, that you sleep inside. They are perfect for those looking to lighten their pack weight. They are also a good option for those who don't feel comfortable sleeping in the open but don't want the bulk of a tent.
Bivvy bags are quick to set up and can be placed almost anywhere, requiring just a flat spot as big as your sleeping mat. They are also cheaper than tents. However, they offer limited space, with little room to do anything other than sleep. They can also be claustrophobic, especially if you need to close yourself in during bad weather.
Tents, on the other hand, offer more space and protection from the elements. They are more comfortable and better suited for multi-day trips. You can keep your backpack and other gear inside a tent, protecting them from the weather and animals. However, they are heavier and more expensive than bivvy bags, and they require more space and time to set up.
Some bivvy bags are like small, single-person tents, with poles that allow them to breathe and hold more gear. These can be a good option for those who want the lightweight portability of a bivvy bag but with a little more space.
When using a bivvy bag, it is important to consider condensation, which can be a problem if the bag is not well-ventilated. It is also recommended to leave a gap of about 6 inches when closing yourself into a bivvy bag to prevent suffocation.
In terms of sleeping mats, some people prefer to place them inside the bivvy bag, while others opt to keep them outside. Placing the mat inside can cause the bag to wear out more quickly, but it offers more freedom to turn over and move around. Keeping the mat outside allows you to sit up more easily in the morning and provides extra space.
Ultimately, the choice between a bivvy bag and a tent depends on your specific needs and preferences. Bivvy bags are ideal for those seeking a lightweight, simple, and affordable option, while tents offer more space, comfort, and protection from the elements.

Waterproofing and condensation
To minimise condensation, it is essential to select a bivvy bag made from breathable fabric. This allows moisture generated during sleep to escape while preventing external moisture from entering. Argon and Nobul are examples of highly breathable non-waterproof fabrics, while eVent fabric is considered more breathable than Gore-Tex. The Montbell Breeze Dry-Tec Bivy Bag 6.4 oz is also mentioned as a product that effectively prevents condensation.
The colour of the bivvy bag also influences condensation levels, with black bivvy bags radiating and condensing more than lighter colours.
Additionally, the temperature can significantly impact condensation. At temperatures below freezing, condensation turns to ice, which can be brushed off and managed more easily. In contrast, temperatures hovering around freezing tend to result in higher condensation levels.
To address condensation, some individuals recommend using a Vapor Barrier Liner (VBL) or a waterproof sack inside the sleeping bag to manage moisture. This approach is particularly useful in colder temperatures, allowing users to carry a thinner sleeping bag. However, it is important to note that VBLs can feel warm and clammy.
Proper setup and site selection can also reduce water exposure. Choosing elevated ground helps avoid pooling water, and using a tarp or tent over the bivvy site provides additional protection from the elements.
Finally, it is worth noting that condensation can occur due to external factors such as rain, leaks, or bringing wet clothing into the bivvy bag. Therefore, it is essential to stay dry, keep your gear off the ground, and avoid getting into the bag with wet clothes.

Safety concerns
Bivvy bags are a great alternative to tents when camping outdoors. They are thin, lightweight, compact, and flexible, allowing you to sleep almost anywhere. However, there are some safety concerns to be aware of when using a bivvy bag.
Firstly, it is important to choose a safe spot to set up your bivvy bag. Select a flat area free from rocks, roots, or other hazards such as falling tree limbs. It is also crucial to consider the terrain and choose a spot that will not flood in the rain. Additionally, look for a location with a nearby water source, as access to water is essential for hydration and cooking during your camping trip.
Another critical safety concern is the risk of suffocation when using a bivvy bag. It is vital to leave a gap of about 6 inches when enclosing yourself in the bivvy bag to prevent asphyxiation. Bivvy bag makers typically include this warning, as there have been reported cases of people dying from suffocation inside their bivvies.
Furthermore, condensation can build up inside the bivvy bag, especially if you breathe inside it. This condensation can dampen your sleeping bag and impact its insulation properties, leaving you feeling cold. To mitigate this, ensure your bivvy bag is well-ventilated and consider using a tarp or groundsheet underneath to protect your gear from moisture.
Additionally, it is worth considering the security aspect of sleeping in a bivvy bag. While some people feel safer in a bivvy bag as they can see their surroundings, others may feel more vulnerable, especially if they are alone. If camping solo, consider your location and choose a spot that offers some privacy and seclusion from passers-by.
Lastly, when packing your bivvy bag, ensure even weight distribution and easy access. Since the bivvy bag is soft and flexible, you can use it as padding between hard, bulky objects in your backpack. Also, consider waterproofing your bivvy bag and sleeping bag to minimize the risk of getting wet during your camping trip.
In conclusion, while bivvy bags offer a flexible and lightweight option for outdoor sleeping, it is important to be aware of potential safety concerns. By choosing a safe location, preventing suffocation and condensation, addressing security concerns, and properly packing and waterproofing your gear, you can enhance your overall safety when using a bivvy bag during your outdoor adventures.
