What You'll Learn

Sleeping bag liners
Liners come in two main types: mummy-shaped and rectangular (also known as travel sheets). Mummy-shaped liners are designed to slip inside a mummy-shaped sleeping bag, which is tapered towards the bottom to provide a closer fit and extra warmth. Rectangular liners, on the other hand, are designed for use on their own or inside a rectangular sleeping bag. They provide more room for sleepers to stretch out and can sometimes be completely unzipped and used as a comforter.
In addition to their practical uses, sleeping bag liners can also provide protection against insect bites, especially in bug-infested areas. Liners with built-in bug protection, such as the Insect Shield® offered by Sea to Summit, can be a valuable addition to your sleeping setup.

Warmth retention
Sleeping bags are designed to provide warmth and comfort during sleep in outdoor environments. While some bags are designed for classic camping, others are tailored for backpacking trips, offering lightweight and snug designs. Sleeping bag liners are also available and can be used to enhance warmth retention.
Fleece sleeping bag liners are a popular choice for those seeking additional warmth. They are constructed from hollow-core Thermolite® fibres, arranged in a grid pattern to maximise heat retention. This design, coupled with a drawcord footbox, allows users to regulate the temperature within the liner. The footbox can be opened or closed for optimal comfort, and it integrates seamlessly with the footbox of specific sleeping bag models.
Fleece liners are an excellent option for backpackers and travellers who may encounter varying temperatures during their journeys. They provide a significant boost in warmth, particularly when used in conjunction with an appropriate sleeping bag and pad. The liners are also treated with odour control technology, ensuring they remain fresh even after extended use.
Additionally, fleece liners offer versatility in their ability to be used independently as a stand-alone sleeping bag in warmer weather. This feature is especially useful when travelling in multiple seasons or climates. The liners are designed in a mummy shape, which maximises thermal efficiency, and they are equipped with shoulder zippers for further temperature regulation.
Overall, fleece sleeping bag liners are a valuable accessory for those seeking enhanced warmth retention and flexibility when sleeping outdoors. They can be adjusted to suit varying temperature conditions and integrated with compatible sleeping bags for optimal comfort during outdoor adventures.

Odour control
Washing and Cleaning
Firstly, it is crucial to maintain good personal hygiene when using a sleeping bag. Before entering your sleeping bag, ensure you are clean by wiping down with baby wipes or wet wipes, especially your feet, face, and underarms. Additionally, consider changing into clean clothes, such as a clean t-shirt, underwear, and socks, to prevent body oils, sweat, and dirt from transferring onto the bag.
Regularly washing your sleeping bag is essential for odour control. Machine washing is an option for most sleeping bags, but always check the care instructions provided by the manufacturer. Use a gentle cycle with cold or warm water, and avoid using regular detergent, as it may not be suitable for the specialty fabric of sleeping bags. Instead, opt for specialist technical down cleaners or gentle cleaners designed for synthetic or down-filled bags. You can also add an odour eliminator or deodorizer to the wash to target bacteria causing unpleasant smells. Remember to run an extra rinse cycle to ensure no soap residue remains.
If machine washing is not possible, consider spot cleaning stains or dirty marks with a gentle cleaner and a toothbrush. For more comprehensive cleaning, you can fill a tub with cool water and add an odour eliminator, following the product instructions for dilution. Submerge the sleeping bag, saturate it with the solution, and soak it for the recommended time before removing and drying.
Drying and Airing
After washing, drying your sleeping bag properly is crucial for odour control. Air drying is generally recommended, especially for down sleeping bags. Hang the bag outside in a breezy location, preferably in the sun, to allow fresh air to eliminate any remaining odours. If you need to tumble dry, use a large machine dryer on low to medium heat, adding wool dryer balls or tennis balls to speed up drying and break up down clumps. Ensure the bag is completely dry before storing it away.
Between uses, it is essential to air out your sleeping bag daily. Hang it up to air out after each night's use, turning it inside out to dry any moisture trapped inside. If you've been in bear country, avoid using products like Febreeze, as they may attract wildlife.
Liners and Protection
Using a sleeping bag liner can provide an additional layer of protection against odours. Liners made from cotton, silk, wool, or polyester act as a barrier between your skin and the bag, keeping it cleaner. They are lightweight and easy to wash, adding convenience to your camping trips.
Additionally, be mindful of other sources of odours, such as sunscreen, cooking odours, and dirt from the ground. Wipe off any sunscreen residue before entering your sleeping bag, change out of clothes you cooked in, and consider placing a pad on the ground before setting up your sleeping bag outdoors.
By following these comprehensive odour control tips, you can maintain the freshness and longevity of your sleeping bag fleece, ensuring a pleasant and comfortable outdoor experience.

Fleece vs other materials
Sleeping bags are available in a variety of materials, each with its own advantages and disadvantages.
Fleece
Fleece is a soft, moisture-wicking, and quick-drying fabric. It is also bulky, especially the mid- and heavyweight varieties. Fleece liners can add up to 12°F of warmth to a sleeping bag. They are ideal for use in varying temperatures. For instance, if you're camping at a base camp that is much warmer than the higher-altitude camps, you can sleep in just the fleece liner at the base camp and use the sleeping bag at the higher camps.
Down
Down sleeping bags are made of small down feathers from ducks and geese. They are lightweight, durable, and pack down well, but they are also more expensive. Down is warmer for its weight than synthetics, so it is often used in backpacking bags. However, wet down will not maintain warmth and is difficult to dry once wet.
Synthetic
Synthetic sleeping bags are more affordable, dry faster, and can provide warmth even when damp. They are ideal for camping near civilization but not for backpacking because they are bulkier than down sleeping bags.
Cotton
Cotton sleeping bags are strong, durable, and absorbent. They are economical but not the lightest or most compact. Cotton liners are ideal for hot and humid conditions. They are also easier to launder than an entire sleeping bag.
Silk
Silk sleeping bags are very lightweight (around 5 oz) and compact. They help insulate in cold weather but are also absorbent and breathable in warm weather. Silk liners are ideal for cold conditions, but they are more expensive than other options.
Microfiber
Microfiber sleeping bags are moisture-wicking and breathable, making them suitable for humid conditions. They also offer some stretch, which is ideal for restless sleepers.

Backpacking bags
A sleeping bag fleece is a liner that can be used to add warmth to your sleeping bag. They are great for backpackers and travellers who sleep in hostels, and they can also be used on their own in hot climates. Sleeping bag fleeces are heavier than silk liners but provide more warmth.
When choosing a backpacking bag, there are several factors to consider. Firstly, you should think about the frame type, the location of important pockets, padding, and ventilation. It is also important to ensure that the bag fits your torso length and hip circumference correctly. You can seek advice from a fit expert in-store. Backpacking bags can range in price from under $200 to over $500.
The capacity of your bag will depend on the duration of your trip and the gear you need to bring. Bags can range in capacity from 30 to 70+ litres. It is important to consider the weight of your pack, which can be tricky to determine. However, an REI pack-fit pro can help you figure out the ideal weight and provide tips for reducing weight.
There are several types of sleeping bags available, including synthetic and down options. Synthetic bags are more affordable, dry faster, and provide warmth when damp. On the other hand, down bags are lightweight, durable, and compress into a small size. Backpacking bags are generally lighter and snug compared to camping bags, which offer more room to move around in. The most common sleeping bag shapes are rectangular, semi-rectangular, mummy, and double. Rectangular bags allow plenty of room for movement, while mummy-shaped bags offer a compromise between warmth and roominess.
