THINGS TO CONSIDER WHEN BUYING A SLEEPING BAG

Warmth: Ensure Your Chosen Bag Will Cater for Your Typical Hikes

The warmth of a sleeping bag is determined by its temperature rating, which is often indicated as a "comfort", "lower limit" and “extreme” range. The "comfort" rating is the lowest temperature at which an average person (in thermals) will feel comfortable, while the "lower limit" rating is the lowest temperature at which a standard male (in thermals) can sleep in a curled up position and maintain thermal equilibrium. The “extreme” rating is the range where there is a risk of health damage by hypothermia or strong sensation of cold, a sleeping bag should only be used in this range in an emergency.

To choose the right bag, consider the lowest temperatures you are likely to encounter on your trips and select a bag rated slightly lower than that to account for unexpected cold snaps (the coldest temperature ever recorded in Australia was -23°C at Charlotte Pass in 1994). Remember that other factors, like the type of sleeping pad you use, your personal metabolism, and even what you wear inside the bag, can also affect warmth. It's also important to know whether you sleep warm or cold, as this will influence the temperature rating you need.

Bag Shape: A Balance Between Comfort and Warmth

Sleeping bags come in various shapes, each designed for different types of sleepers and conditions. Mummy bags are the most thermally efficient because they contour closely to the body, reducing dead air space and retaining heat more effectively. However, they can feel restrictive, especially for those who like to move around while sleeping. Semi-rectangular or tapered bags offer a compromise, providing more room in the shoulder and leg area while still retaining some warmth. Rectangular bags are the roomiest, ideal for those who prioritize comfort over heat retention. For those looking for the best of both worlds, consider bags with adjustable features, like drawstring hoods or extra-wide shoulders.

Fill Material: Down Vs. Synthetic

Choosing between down and synthetic fill depends on your specific needs and the conditions you plan to encounter. Down is the best choice for cold, dry climates due to its excellent warmth-to-weight ratio and ability to compress into a small size. However, it loses its insulating properties when wet and can take a long time to dry (some down-insulated sleeping bags at Tom’s are hydrophobically treated, boosting their ability to stay loft and dry in ). If you plan on hiking in wet or humid environments, synthetic fill is a better option. It retains warmth when wet and dries faster, though it is bulkier and heavier compared to down.

Additionally, down comes in various quality grades, often measured by "fill power"—the higher the fill power, the better the quality and warmth-to-weight ratio. Consider hydrophobic down, which is treated to resist moisture, if you want the benefits of down but expect damp conditions.

Features: The Sky Is the Limit Here

Sleeping bags come with a variety of features that can enhance comfort, convenience, and performance. Look for draft collars and draft tubes along the zippers to prevent heat loss. A hood with a drawstring can trap heat around your head, which is crucial in colder conditions. Some bags offer different zip options (full-length, half-length, or double zippers) for better ventilation or to use as a quilt. Internal pockets can store small items like a phone or a flashlight. Additionally, some bags have water-resistant outer fabrics to protect against condensation and light moisture. While these features can add value, they might also increase weight and cost, so prioritize according to your needs.

Weight and Size: Light and Compact Is Better

The weight and packed size of a sleeping bag are crucial factors for hikers and backpackers who need to minimize their load. Generally, a lighter bag is easier to carry, but this often means sacrificing some comfort or warmth. Down bags tend to be lighter and more compressible than synthetic ones, making them ideal for long-distance trekking. However, if you prioritize durability and moisture resistance, synthetic bags may be the better choice. When choosing a sleeping bag, check the "stuff sack" size to ensure it fits well into your pack and consider a compression sack to further reduce bulk.

Your Budget: Buy the Best Bag You Can Afford

While it may be tempting to buy a cheaper bag, investing in a high-quality sleeping bag can pay off in the long run. Better materials, higher-quality insulation, and more refined construction often lead to a longer-lasting and more comfortable sleeping bag. Think about your intended use: if you're just starting and plan to hike occasionally, a mid-range bag might suffice. However, if you’re a frequent hiker or planning extreme adventures, it’s worth spending more on a bag that offers superior warmth, weight, durability, and features. Remember that a good sleeping bag is an investment in your comfort and safety while outdoors.
