Design & Durability
Designed with a dual zipper that allows the sleeping bag to open completely, this sleeping bag is compatible with other sleeping bag models for couples or campers with young children who want to create a larger sleeping space. The TerraLite takes into account that there is nothing more important to the quality and function of a sleeping bag than its insulation.
It is insulated with 850+ fill power premium goose down, the lightest and most compressible down available, and includes an insulated hood with adjustable draw closure and a three dimensional down filled draft tube for keeping the cold out and body heat in. A continuous baffle construction ensures that the down insulation doesn’t isolate to one side over time or after multiple uses.
Constructed with a 12 denier rip-stop nylon outer shell for durability and 15 denier nylon taffeta lining providing a plush and soft layer against your skin, the TerraLite is a comfortable mummy bag that keeps you protected from outside elements while you sleep soundly. The shell is treated with a surface durable water repellent finish which sufficiently shrugs off dew and condensation.
With a water repellent finish you can feel ensured that condensation from tent walls or sleeping outside under the stars won’t leave your sleeping bag weighed down with dampness. The finish can also be easily reapplied over time if it begins to wear.
It’s important to always keep the weather in mind when you’re choosing a sleeping bag. You want to choose a sleeping bag that is rated for the temperature range you plan to go camping in so know which seasons you plan to use this sleeping bag for. The TerraLite sleeping bag has a 25°F temperature rating making it ideal for spring and fall camping.

On cold nights the adjustable drawstring hood and insulated draft tube will help keep your body warmth in and the cold out. The wide mummy design of this sleeping bag also allows you to stay comfortable while sleeping with extra layers on if the temperature drops unexpectedly.
On warmer nights, take advantage of the dual zipper design which allows the sleeping bag to unzip completely. You can unzip it and sleep on top of your sleeping bag or keep your feet unzipped to let some cool air in. With all of the temperature control features that the TerraLite offers, you’ll be comfortable camping in almost any weather conditions. Keep in mind that sleeping bag manufacturers display the ideal weather use with a temperature rating, but these ratings are just guidelines so use your best judgment.

This mummy bag is designed for ultimate sleeping comfort, especially for those with a wide frame or who are often restless sleepers. Wide throughout the middle for side sleeping comfort, the mummy design offers a comfortable shape without added weight.

A full length YKK zipper to enable you zip up during the cold nights or zip down to let air in when it’s hot and a 6 inch right zip for the left handed campers. Additionally, there is a 5 inch loft that limits heat loss and maintains thermal performance of the bag.
We cannot forget to mention the continuous baffles that allow you to control the temperature in the sleeping bag by adjusting it to your desired warmth. They lack a side baffle which lets you shift the down during warm weather and three season use. When it’s hot, you should move some of the down towards the bottom to reduce insulation at the top of the bag. During cold nights, just move the down back to the top to increase insulation.
Weighing around 3.7 pounds, you might notice that it’s a bit bulkier than the TerraLite which weighs just under 2 pounds.

They also act as a barrier that keeps the down from migrating from the top to the bottom particularly in cold weather. The 800 fill power only goes to make it lighter, despite the weight.
With the price range of around $560 to $570, the North Face Inferno is much more costly than the TerraLite.
