When preparing for outdoor activities such as camping, it is important to know whether your sleeping bag can catch fire. Fire outbreaks are a major risk when outdoors, and choosing fire-retardant gear is one way to minimize this risk. Sleeping bags are made from three layers: an outer layer, an inner layer, and fill material. The outer layer is typically made from synthetic fibres such as nylon, polyester, or DryLoft material, which are less flammable than natural fibres. However, some sleeping bags are treated with fire retardant chemicals, usually on the outer surface, to prevent or slow down the burning process. While most sleeping bags are coated with a layer of DWR (Durable Water Repellent) to repel moisture, some bags are also treated with fire retardants. This has sparked a debate about the safety of using such chemicals, with some companies choosing to produce sleeping bags without any chemical treatments.
| Characteristics | Values |
|---|---|
| Fire-retardant treated sleeping bags | Most sleeping bags are coated with a layer of DWR (Durable Water Repellent) to repel moisture and combat condensation. However, some sleeping bags are not treated with DWR and are instead labelled as "fire-retardant". |
| Fire-retardant chemicals | Some sleeping bags have fire-retardant chemicals applied to them to resist fire. However, this is debatable as some companies claim that they do not apply fire retardants to their sleeping bags. |
| Fire-resistant options | Sleeping bags that are fire-resistant without the use of chemicals are considered safer for use. Down-filled sleeping bags are not considered flammable and are one of the least flammable bedding materials. |
| Flammability | Synthetic-filled sleeping bags have a low flammability rating as they require more heat to ignite. When on fire, these materials can melt unless they are specially treated to resist fire. |
| Fire safety | To minimize the risk of fire outbreaks while camping, it is recommended to maintain a minimum distance of 3 meters between the campfire and your sleeping bag. |

Fire-retardant chemicals are applied to sleeping bags to resist fire
Some companies apply fire-retardant chemicals, usually to the outer surface of sleeping bags, because they believe the chemicals slow down or prevent the burning process if a sleeping bag catches fire. Whether they do or not is debatable. Manufacturers are required to ensure their products pass a flammability test before going to market. The American Standard Test Method of Flammability (ASTM F1955-20) outlines the process. Washing or dry-cleaning sleeping bags multiple times may increase their flammability as the protective coating can wear out. They are also tested following tight storage conditions, which might impact the rate of fire spreading.
Some sleeping bag companies, such as Wiggy's, do not apply fire retardant chemicals to their fabrics. Instead, they use pure finish fabrics, which means there are no chemicals applied to them, making them safe for chemically sensitive people. Other companies that offer sleeping bags without fire retardant treatments include Jacks 'R' Better, Wildkin, and Holy Lamb Organic.

Fire-retardant sleeping bags are not fireproof
Many sleeping bag manufacturers treat their products with fire-retardant chemicals, and some government regulations require the fabric burn rate of all sleeping bags to be tested. However, it is important to note that fire-retardant sleeping bags are not fireproof. While these treatments can help slow down the spread of flames and give you valuable time to escape in an emergency, they will not prevent the bag from burning entirely if exposed to a large fire.
The key difference between fire-retardant and fireproof is that fire-retardant materials are treated with chemicals that enable them to self-extinguish when exposed to a small flame. On the other hand, fireproof materials have inherent properties that prevent them from catching fire, regardless of the size of the flame.
Fabrics treated with fire-retardant chemicals may also melt or drip when exposed to flames, which can be dangerous. Additionally, these chemicals can have negative environmental impacts, as highlighted by Greenpeace. Some of the chemicals used, such as organohalogen and organophosphates, can find their way into aquatic systems and marine life and persist without breaking down easily.
When choosing a sleeping bag, it is essential to understand the limitations of fire-retardant treatments. Even with these treatments, sleeping bags are not immune to fire damage. Always exercise caution when using a sleeping bag near any source of flame and follow the safety guidelines provided by the manufacturer. Additionally, consider exploring alternative options, such as naturally fire-resistant materials like Kevlar, which do not rely on chemical treatments for their fire-resistant properties.
While fire-retardant sleeping bags can provide some level of protection against small embers or flames, they should not be relied upon as a guarantee of safety. It is crucial to prioritize fire safety and maintain a safe distance from open flames when using any sleeping bag, regardless of its fire-retardant properties.

Down-filled sleeping bags are not considered flammable
When it comes to sleeping bags, safety is a key consideration, especially when camping near a fire. While sleeping bags are not fireproof, most are flame retardant, meaning they are not a fire hazard and will not easily catch fire. This is due to the outer layer or shell of the sleeping bag, which is typically made from materials such as nylon, polyester, or DryLoft, which have a low flammability rating.
Down-filled sleeping bags, in particular, are not considered flammable. Down is one of the least flammable bedding materials and exhibits significant resistance to fire. This is because down bags allow smouldering to move through the bag, rather than containing the embers and causing a fire. However, it's important to note that the outer material of a sleeping bag plays a crucial role in determining its flammability. Tightly woven synthetic fibres, for example, don't ignite easily but may melt and create a burn hole when exposed to fire.
The weave and weight of the outer layer are also important factors in sleeping bag flammability. Washing can wear away at this protective layer, so proper care is essential to maintain the flame-retardant properties of the sleeping bag. While some companies choose to treat their sleeping bags with fire-retardant chemicals, others, like Wiggy's, pride themselves on using pure finish fabrics without any chemical treatments, making them suitable for chemically sensitive individuals.
In terms of legislation, both the United States and Canada have similar guidelines regarding sleeping bag flammability. While specific requirements may vary across states and regions, the general consensus is that sleeping bags should burn at a slower rate to enhance consumer safety. For example, the United States Rate of Burn Standard for Sleeping Bags stipulates that sleeping bags cannot burn at a rate faster than 15 centimetres per minute. This standard is also followed in Canada, where it is known as the Standard Test Method for Flammability of Sleeping Bags.

Synthetic-filled sleeping bags have a low flammability rating
Sleeping bags are made from three layers: an outer layer or shell, an inner layer or lining, and fill material. The shell is typically made from nylon, polyester, taffeta, ripstop nylon/polyester, or DryLoft material. The inner layer usually consists of nylon, synthetic, cotton, or poly-cotton material. The fill material provides insulation and is typically natural (down, cotton, or wool) or synthetic (poly fibre).
Washing or dry-cleaning sleeping bags multiple times may increase their flammability as the protective coating can wear out. In Canada, the Standard Test Method for Flammability of Sleeping Bags (ASTM F1955-20) tests the burn rate of sleeping bag materials. The American equivalent is the Rate of Burn Standard for Sleeping Bags (CPAI-75:1976A). A sample of the sleeping bag material is set on fire under specified conditions, and the burn rate is denoted in centimetres per minute.
Many sleeping bags are treated with a Durable Water Repellent (DWR) finish. This is an industry measure of durability that suggests that 80% of the DWR is retained after 20 washings. However, this rating is for laboratory test procedure only and is not realistic for home washing. Some sleeping bags are filled with down that has a water-repellent treatment to combat down's loss of insulating efficiency when wet. Synthetic insulation also offers solid performance when wet, as it continues to insulate when damp.
