REDCAMP Ultra Lightweight Sleeping Bag

The Redcamp Ultra Lightweight sleeping bag is made from polyester and offers high-quality and durable fabric which stands up to years of use, which will comfort you during the challenging times.

How Ultra is the Ultralight?

An ultralight sleeping bag, before anything else, needs to be just that – ultralight. The lightness of the sleeping bag is extremely important when looking at the ultralight range. The typical ultralight sleeping bag usually weighs just under 2lbs. Sleeping bags, teamed up with a tent and a backpack are all part of the “Big 3” structure that any survivalist out there follows. The three items ideally should weigh 9lbs, which will help to save as much weight as possible, adding to the ease when you are on your feet. The weight of ultralight sleeping bags vary by several ounces, but if you plan to be on foot during your survival experience then the weight of the sleeping bag is definitely a focus to emphasize.


If you’re on the run, the last thing you want added to your journey is a weight burdening your limits. That’s why you should always consider the ways in which you can get rid of the bulk of the sleeping bag. However, the climate you find yourself in with contribute to your final decision. It all varies depending on your warmth and insulation requirements, i.e., a summer bag will compress smaller than a winter bag due to nonessential insulation.

Sleeping Bag Temperature

We all come in different shapes and sizes and our bodies produce different levels of insulation, so it is good to consider your own body heat during your hunt. The desired temperature of the ultralight sleeping bag will vary based on the weather conditions you will be enduring. As well as this, you need to consider if you are a hot or cold sleeper, what attire you like to sleep in and whether you will be in the tent while using the sleeping bag. The temperature rating of the individual sleeping bag will vary depending on the region or country you are in, so it’s always best to check the product description before purchase. Consider if the sleeping bag is designed for the summer, winter or is three-season. Sometimes the quality and warmth of the ultralight sleeping bags is sacrificed because of how feather-like they are.

Spacious Interior

Ultralight sleeping bags are known to be narrowly designed, which can be a problem either way. The more space the sleeping bag has reduces the airflow circulating around your body. The less space also interferes with the fidgitting survivors out there battling for rest. Length, shoulder girth and hip measurement are the three key measurements to take into consideration when choosing the best sleeping bag for you. Regular and ultralight sleeping bags tend to come in two sizes, for both male and female. The sizes vary in length and width, and all really comes down to your own personal size and preference. Shoulder girth and hip measurement are crucial to comfort and will determine whether or not you get a good night’s sleep. How spacious the sleeping bag is will either dampen your experience or will give you the comfort to carry on and push yourself further.

Getting In and Out of the Sleeping Bag

Manoeuvering in and out of your tent, especially during the nighttime, is inevitable and therefore an easy entry and exit is something to review throughout your search. With sleeping bags zippers, it all comes down to preference. Long length zippers are considered to be more practical, say if you were reading during your winding-down time, or if you are a heavy sleeper who doesn’t mind constriction then the short length zippers are for you.

The Battle of Down vs Synthetic

In the survival world, the ultimate battle is choosing between down or synthetic insulation. It is one of the biggest backpacking debates, and here’s why: Down feathers are lighter, warmer and pack smaller compared to synthetic insulation options. You should consider what time of year you are venturing out because down also has an Achilles heel, which loses loft and insulation ability in wet conditions. We discussed earlier the importance of temperature ratings when on the lookout for a new ultralight sleeping bag, and checking the type of insulation used is vital. Overall, down insulation is suited to those on a budget and the synthetic insulation tends to be of a premium range.

Storage Advice

Less loft means less insulation for an ultralight sleeping bag and therefore how you store your sleeping bag when not in use is essential to the longevity of the product. If you desire to keep your sleeping bag for a long period of time then it is suggested to keep it in a fluffy state as much as possible, rather than flattened away decreasing the loft of the bag.


Ultralight sleeping bags are arguably one of the most essential components to a survival kit, without one, you wouldn’t receive the warmth, comfort and protection from the outdoors, to survive the unknown. With many ultralight sleeping bags on the market, it can be a challenge to not only find the best of the best but one that will entertain your own personal needs. Despite being spoiled for choice, my pick for the best ultralight sleeping bag would be the Nemo Men’s Riff Down Sleeping Bag. This ultralight sleeping bag has climbed to the top of the list for a variety of reasons. It is three season which makes it suitable for various weather conditions with its down filling which covers you all year long. The footbox included helps to withstand tent and bag condensation, which is crucial to It is a contemporary design which will appeal to all generations. It is, compared to the rest, of a premium price but for quality and longevity, this is the one I recommend. However, all of the choices we have analysed throughout would make excellent options for an ultralight sleeping bag.
