Temperature ratings
When choosing a sleeping bag, the key factor is its temperature rating. The temperature rating of a sleeping bag is the lowest temperature at which the bag will keep the sleeper comfortable. This is further divided into two ratings: the Comfort rating and the Lower Limit rating. The Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, while the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable.
The temperature rating of a sleeping bag is determined through independent testing protocols, such as the International Organization for Standardization (ISO) 23537 or the European Norm (EN) 13537 for older items. These tests are based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
When selecting a sleeping bag, it is recommended to choose one with a temperature rating below the lowest expected nighttime temperature during your trip. For example, if you are camping in an area where the temperature is expected to drop to 30°F, you should choose a sleeping bag with a temperature rating of 30°F or lower. This will ensure that you stay warm and comfortable throughout the night.
Additionally, different types of insulation, such as synthetic or down, will also affect the warmth of the sleeping bag. Synthetic insulation is typically more affordable and continues to insulate when damp, making it a good choice for wet conditions. On the other hand, down insulation is more expensive but performs better in cold, dry weather. It is also more lightweight and compresses into a smaller size, making it a popular choice for backpacking bags.
Both REI and The North Face offer sleeping bags with a range of temperature ratings, allowing you to choose the one that best suits your needs and preferences. It is important to consider the type of activities you will be using the sleeping bag for, as well as the expected temperature conditions, to make an informed decision.

Bag shapes
Rectangular sleeping bags offer ample room for legs and arms to stretch out, making them ideal for campers. They can also be completely unzipped and used as comforters.
Semi-rectangular bags, also known as modified mummy or barrel shapes, offer a compromise between warmth and roominess. They are suitable for those who want more space than a traditional mummy bag but don't need the full room of a rectangular bag.
Mummy bags have a snug fit to boost warmth and reduce weight. With this style, you roll over with your bag rather than inside it. Mummy bags are a good choice for backpacking as they are lightweight and pack down small.
Double sleeping bags are designed for two people and are ideal for couples. Alternatively, two rectangular bags can be zipped together to form a double bag, but they need to be the same model and brand.
In addition to the bag shape, other factors such as insulation type, temperature rating, and size (regular, long, or short) should be considered when choosing a sleeping bag. The North Face offers a variety of styles, including insulated down sleeping bags, bivy sacks, and mummy bags. REI sleeping bags are available in various shapes and temperature ratings, with options for camping and backpacking.

Insulation type
When it comes to insulation type, there are two main options: synthetic and down. Synthetic insulation is more affordable, dries faster, and still provides warmth when damp. It is a good choice for camping in cold, damp conditions. Synthetic insulation is also found in sleeping bags designed for backpacking because it is lightweight and packs down small.
Down insulation, on the other hand, is more expensive but performs better in cold, dry weather. It is lightweight, durable, and compresses small. For cold, damp conditions, down insulation that has been treated to be water-repellent can be a good option.
The North Face Furnace 20 sleeping bag is insulated with water-resistant ProDown, which dries faster than traditional down. It also features an anti-compression layer composed of Heatseeker™ Eco synthetic insulation along the bottom panel to eliminate cold spots.
The North Face Guide 20 sleeping bag features proprietary Heatseeker™ Guide insulation, a blend of cut-staple and continuous-filament insulation that is lightweight and long-lasting. This insulation is wrapped around the bag in efficient, compressible vertical baffles, making the bag 17% more compressible than similar options.
It's important to note that while down bags are generally considered warmer, the temperature rating is the best indicator of warmth as many factors contribute to the overall warmth of a sleeping bag.

Budget
When it comes to budget, REI and The North Face both offer sleeping bags at different price points. REI's budget sleeping bags include options for backpacking and car camping, with varying temperature ratings, packability, and weights. The REI Co-op Trailmade 20 and Kompact 30F are popular budget options, with the Kompact 30F offering exceptional spaciousness and comfort. The REI Co-op Trailmade 20 is lightweight and compact, making it ideal for backpacking.
The North Face also offers budget-friendly sleeping bags, such as the Wawona Bed 20, which is known for its comfort and build quality. However, it is heavier and bulkier than some other options, and it is not designed for backpacking or travelling far from your car. The North Face also offers a two-person version of the Wawona Bed, which is a more affordable alternative for couples or those willing to compromise on features and comfort.
In terms of price, the REI budget sleeping bags are typically priced at around $100 or less, while The North Face's Wawona Bed 20 is considered fairly priced but may be more expensive for some budget-conscious campers. Additionally, The North Face offers other budget options, such as the Coleman Brazos 20 and Teton Sports' Celsius, which are more affordable but also a step down in quality.
Overall, both REI and The North Face provide a range of budget-friendly sleeping bags, but the specific features, temperature ratings, and prices may vary between the two brands. It is essential to consider your priorities, such as weight, packability, warmth, and cost, when making a budget-conscious decision.

Features
When it comes to sleeping bags, there are several features to consider when deciding between REI and North Face. Here are some key attributes to help you make an informed decision:
Temperature Ratings
The most crucial factor when choosing a sleeping bag is its temperature rating. Select a bag with a rating that suits the expected nighttime temperatures during your camping or backpacking trips. Both REI and North Face offer a range of temperature-rated sleeping bags. For example, the North Face Furnace 20 is a 3-season backpacking bag, while the North Face Guide 20 is suitable for colder conditions.

The North Face Furnace 20 uses water-resistant ProDown insulation, a blend of synthetic and down insulation, to offer the best of both worlds.
Shape and Size
Sleeping bags come in various shapes, including rectangular, semi-rectangular (or modified mummy), and mummy. Rectangular bags offer ample room to stretch, while mummy bags are snug to conserve warmth and reduce weight. Some bags, like the North Face Furnace 20, feature a comfort-oriented shape that provides a balance between warmth and roominess. Additionally, sleeping bags come in different sizes, such as short, regular, and long, so you can choose the one that best fits your body type.
Additional Features
Consider sleeping bags with features that enhance durability, warmth, and functionality. For instance, a waterproof shell, a snug-fitting hood, draft-blocking details, extra zippers, and a stash pocket can improve your sleeping bag's performance and convenience. The North Face Guide 20 features a ripstop nylon shell for durability, while the North Face Furnace 20 has an anti-compression layer to eliminate cold spots.
Both REI and North Face offer an array of sleeping bags with distinct features to cater to different needs. Compare the available options and consider your specific requirements, budget, and intended use to make an informed decision about which brand and model best suit your camping or backpacking adventures.
