What You'll Learn
Sleeping bag type and compressibility
The size of the stuff sack for a sleeping bag depends on the sleeping bag's size, shape, and fill. Sleeping bags filled with down are more compressible than synthetic-filled ones and require smaller volume stuff sacks. Synthetic insulation-filled sleeping bags, on the other hand, do not compress as well and require larger volume stuff sacks. The type of insulation is the primary factor determining the size of a sleeping bag when it is in its stuff sack.
Down sleeping bags are highly compressible and ideal for backpacking as they are lightweight and take up minimal volume when compressed. They are also suitable for car camping if moisture resistance is not a concern, as they maintain their insulating properties even when wet. However, they may be more expensive. An example of a highly compressible down sleeping bag is the Swallow, which is extremely light, warm, and compressible, but it has a narrower cut and is quite pricey.
Synthetic sleeping bags are typically more affordable and widely available under various branded names. They are suitable for car camping and damp climates as they continue to insulate when wet. However, they are bulkier and less compressible, making them less ideal for backpacking. The compressed volume of synthetic sleeping bags can vary depending on their filling density and weight. For example, a bag with 150 g/m2 polyester fibre fill will take up more volume and weigh more than a bag with 80 g/m2 fill, while providing similar warmth.
Some sleeping bags feature a blend of down and synthetic insulation, with synthetic insulation on the bottom for better compression resistance and down on top for better loft. However, this design advantage is lost if the bag is rolled onto its side.
When choosing a sleeping bag, it is essential to consider factors such as temperature rating, sleep system, insulation type, weight, and cost. The warmth-to-weight ratio is particularly crucial for backpackers, as a cold backpacker will not sleep well. It is recommended to choose a sleeping bag with a temperature rating slightly lower than the anticipated low temperatures of your backpacking trips. Additionally, look for ""compressed volume" specifications to better understand the size differences between different sleeping bags.

Dry bags for weather protection
Dry bags are an essential piece of kit for any outdoor adventure, from camping in unpredictable weather to kayaking and canoeing. They are designed to keep your gear dry and dust-free, offering protection from the elements.
When choosing a dry bag for your sleeping bag, it's important to consider the size and shape of the sleeping bag, as well as the fill. Down-filled sleeping bags, for example, are more compressible and require smaller volume stuff sacks than synthetic-filled bags. If you're planning to camp in winter conditions, a compression sack is recommended to reduce the volume of your sleeping bag inside your backpack.
Zpacks offers a range of dry bags in different sizes. Their full-size roll-top dry bag, for instance, can accommodate larger sleeping bags, multiple clothing items, or other soft bulky items. It fits well in their backpacks, either vertically or horizontally, depending on the pack volume. The wide opening makes it convenient to access your gear.
For shorter trips, Zpacks also offers a 3-4 day Big Food Bag, which can be used to store food items and keep them protected from the elements. This bag is made from thicker 1.6 oz/sqyd Dyneema® Composite Fabric to withstand abrasion and resist small rodents.
Other notable dry bags on the market include the Ortlieb Dry-Bag, which is durable, watertight, and available in multiple sizes. The Marchway Floating Waterproof Dry Bag is another affordable option, offering five different sizes to choose from. The 10-liter bag, for example, can easily accommodate supplies for a day on the water, including a towel, book, snacks, and other essentials.
Whether you're camping, kayaking, or canoeing, dry bags provide essential weather protection for your gear, ensuring that your items stay dry and safe during your outdoor adventures.

Ultralight stuff sacks for weight reduction
Stuff sacks are essential for keeping your backpack organised. They are especially useful for storing sleeping bags, tents, and other gear. The type of stuff sack you need will depend on the size and shape of your sleeping bag, as well as its fill. Down-filled sleeping bags, for example, are more compressible than synthetic-filled ones and will require a smaller volume stuff sack.
If you're looking for an ultralight stuff sack to reduce weight, there are a few great options available. Zpacks offers a range of lightweight stuff sacks made from Dyneema Composite Fabric. These sacks are perfect for organising miscellaneous items, small clothing items, or larger items like sleeping bags, tents, and bulkier soft goods. The rectangular shape of their Big Stuff Sack fits perfectly in larger backpacks, either vertically or horizontally, and can fit multiple clothing items or a bigger sleeping bag.
Hyperlite also offers a range of premium ultralight Dyneema stuff sacks, pods, and waterproof gear, ideal for thru-hikes and backcountry adventures. Their products are designed to be lightweight and durable, with only the essential features, making them perfect for minimising pack weight.

When choosing an ultralight stuff sack, it's important to consider the size and shape of your sleeping bag, as well as the level of compression you need. For winter weather sleeping bags, for example, a more complex compression sack may be necessary to reduce the volume in your backpack. Additionally, switching from nylon to Dyneema Composite Fabrics can significantly reduce weight, as Dyneema is known for its lightweight and waterproof properties.

Size and shape of the sleeping bag
The size and shape of a sleeping bag are important factors to consider when choosing a stuff sack. Sleeping bags are sized primarily by their length, which should correspond with the height of the sleeper. For example, a 6-foot-tall person should consider a sleeping bag that is around 6 feet 8 inches long, allowing for extra room for a correct fit. Sleeping bags generally come in small (5 ft. 6 in.), regular (6 ft.), and long (6 ft. 6 in.) sizes.
The shape of the sleeping bag also plays a role in determining the size of the stuff sack required. Mummy-shaped sleeping bags are tapered towards the feet, making them the warmest and most lightweight option as they minimise the amount of air that needs to be heated. This shape is ideal for backpacking due to its packability. Rectangular sleeping bags, on the other hand, offer more room for the legs and arms to stretch out and are popular for car camping due to the freedom of movement they provide. They are less efficient at heating but can sometimes be completely unzipped and used as a comforter. Semi-rectangular bags, also known as "modified mummy" or "barrel" shapes, offer a compromise between warmth and roominess. They are less warm than mummy bags but can still be efficient for shorter backpacking trips.
The type of insulation in a sleeping bag also affects its size and the volume of the stuff sack required. Sleeping bags with down insulation are more compressible and require smaller volume stuff sacks, including regular dry sacks, whereas synthetic-filled bags are less compressible and need higher-volume stuff sacks, possibly including compression sacks. The weight of the insulation is also a factor, with more efficient insulations delivering greater warmth for less weight.
Therefore, when considering the size and shape of a sleeping bag in relation to choosing a stuff sack, it is important to take into account the length, shape, and insulation type of the sleeping bag, as well as the height and intended activity level of the sleeper.

Storage of multiple items
The size of a stuff sack depends on the volume of items you wish to store. For example, a small stuff sack is suitable for a down jacket, rain jacket, pants, and other small items, while a medium-sized stuff sack can accommodate toiletries, snacks, and other miscellaneous items. A large stuff sack, on the other hand, is ideal for storing multiple clothing items, larger tents, bigger sleeping bags, or other soft bulky items.
When considering the storage of multiple items, it is recommended to use a combination of stuff sacks and other storage solutions. Some essential stuff sacks to consider are:
- A sleeping bag sack: This is essential for keeping your sleeping bag dry and clean. The size of the sack will depend on the type of sleeping bag you have, with down sleeping bags requiring smaller sacks due to their higher compressibility.
- A clothes sack: This will help keep your clothing items organised and protected. The size of the sack will depend on the amount and type of clothing you plan to bring. For example, a 3-season clothes bag will be smaller as it typically holds fewer items, while a larger sack may be needed for bulkier clothing.
- A food sack: This is crucial for storing your food securely and safely. The size of the food sack will depend on the amount of food you need to store and the duration of your trip. For example, a 20-litre sack can hold enough food for 3-4 days.
- A ditty bag: This smaller sack is perfect for storing essential items such as a first aid kit, compass, spare matches, a wallet, and other small items that you want to keep organised and easily accessible.
In addition to stuff sacks, utilising other storage solutions can further enhance the organisation and protection of your gear. For instance, using trash compactor bags or heavy-duty trash bags as liners for your backpack can provide waterproofing for all your items. Additionally, utilising ziplock bags or waterproof sleeves for smaller items, such as electronics, can ensure they remain dry and secure.
Ultimately, the number and size of stuff sacks you require will depend on your personal needs and the gear you plan to bring. It is recommended to consider the duration of your trip, the expected weather conditions, and the specific items you wish to store when determining the appropriate stuff sack sizes for your multiple items.
