3 best thermal sleeping bag

A thermal sleeping bag is a specialized type of sleeping bag designed to provide exceptional insulation and warmth, making it suitable for cold weather camping, hiking, and other outdoor activities. These sleeping bags are engineered to keep you comfortable and protected in frigid temperatures. Here are some key points about thermal sleeping bags:

  1. Insulation: Thermal sleeping bags are heavily insulated with materials like down or synthetic fill. These insulating materials create air pockets that trap your body heat, preventing it from escaping and thus keeping you warm in cold conditions.

  2. Temperature Ratings: These sleeping bags are typically rated for specific temperature ranges. The rating indicates the lowest temperature at which the bag can keep the average person comfortable. It's crucial to choose a sleeping bag with a temperature rating appropriate for the expected weather conditions.

  3. Shape and Design: Thermal sleeping bags come in various shapes, including mummy-shaped bags and rectangular bags. Mummy bags have a tapered shape that snugly fits your body, minimizing the amount of air inside the bag and maximizing warmth. Rectangular bags offer more room but may not be as thermally efficient.

  4. Shell Material: The outer shell of thermal sleeping bags is often made of durable, water-resistant or waterproof materials. This protects the insulation from moisture and helps keep you dry in damp conditions.

  5. Hood and Draft Collar: Many thermal sleeping bags feature hoods with adjustable drawstrings to cover your head and retain warmth. Some also have draft collars near the neck area to prevent heat from escaping.

  6. Zipper Design: The zippers in thermal sleeping bags are designed to minimize heat loss. Some bags have full-length zippers with draft tubes to prevent cold air from seeping through the zipper.

  7. Compression and Packability: Despite their insulation, thermal sleeping bags are designed to be packable. They often come with compression sacks or stuff sacks, allowing you to compress the bag for easier transport.

  8. Weight: Thermal sleeping bags tend to be heavier than bags designed for milder temperatures due to the additional insulation. The weight can vary depending on the type and amount of insulation used.

  9. Versatility: While thermal sleeping bags are primarily designed for cold weather, some models can be used year-round by venting them in warmer conditions. This versatility makes them suitable for various camping adventures.

  10. Price Range: Thermal sleeping bags are generally more expensive than standard three-season bags due to their specialized insulation and cold-weather features.The price can vary widely based on the brand, features, and materials used.

In summary, thermal sleeping bags are essential gear for cold-weather camping and outdoor activities. They offer excellent insulation and protection against the cold, helping you stay warm and comfortable even in harsh winter conditions. When selecting a thermal sleeping bag, consider the temperature rating, shape, and other features to ensure it suits your specific needs.

User questions & answers

Question: how small does it compress down to
Answer: When you get it new it is about 20x12 but I put it in a compression bag and got it down to around 12x12 . I t wasn't easy getting it that small I had to put my knee on it to smash it and really pull on the straps. It is a little heavy for hiking but it has kept​ me very warm into ​the mid teens in a two person hiking tent with a klymit insulated static v sleeping pad under me. I f you can carry the extra weight it is a decent alternative to a more expensive down bag.
Question: I need to know the weight of the sleeping bag please
Answer: It's brutally heavy. If you're asking about weight, this is NOT the bag you want.
Question: Can you wash it on washing machine
Answer: Technically yes. A standard wash may cause the internal insulating fill material to clump together during the spin cycle. This will cause the bag to be uncomfortable and loss it's ability to properly keep you warm. I've ruined sleeping bags this way years ago as a kid. My front loading washer machine was a "hand washing" setting selection with the option to turn the spin cycle off. I wash the bag twice (once with the soap reservoir about one-third full of HE Laundry Soap and a second hand wash cycle with just water to ensure the sleeping bag is properly rinsed. Use cold water on both washing cycles. Finally, let the bag drip dry on a drying line outdoors or indoors in your laundry room or garage. Make sure to turn the bag inside out after 8 to 12 hours of drying so it can finish drying properly. This washing/drying method keeps my sleeping bags from being ruined. Use a quad size washing machine at your local laundry mat to wash your sleeping bag(s) if your current washing machine is too small to handle this sleeping bag. Air dry on line at home. A tower fan pointed at the sleeping bag while it's on the drying line will help the bag dry much faster. Sleeping bag liners are a great way to help it stay clean. They are sold in cotton, satin, silk and various other materials. I find the silk bags are extremely comfortable. The sporting goods section at your local Walmart should sell cotton sleeping bag liners next to the sleeping bag section. Hope this helps you out.

Question: How do you get the sleeping bag back into the stuff sack? I bought is and we can't get it back in
Answer: Most if not all better quality sleeping bags I've bought came with a stuff sack and a storage bag. The storage bag is much bigger and breathes to help preserve loft. (An oversized cotton pillow case would work) As others have said, a stuff sack is for stuffing. Stick the foot in and start stuffing. Sometimes it's a bit of a challenge. I think manufactures tend to provide undersized bags so they can claim they pack down smaller. BTW, this would not make a good backpacking bag. It's heavy and bulky. It would be fine for car camping though. Or for short winter backpack trips if you're on a really tight budget.

User questions & answers

Question: The thermal bivy sack blanket looks big ,are they easily to store
Answer: If you freeze camping you need a warmer bag or more likely a warmer sleeping pad. A good sleeping pad will do more for warmth than any other piece of equipment. You can also add a sleeping bag liner, Alps makes an inexpensive one. A liner can add 5 to 10 degrees to your bags rating. You either sleep cold or warm when sleeping outdoors; if you are warm in a 35 degree bag when it's 35 degrees outside you sleep warm. Woman sleep colder than Men. A 20 degree bag for a Man might be comfortable for a Woman down to only 35. If you sleep cold and you expect to be in 35 degree weather, get a 20 degree bag and a pad with an r-value of 3.2 or above.
Question: How much does one camping bivy sack weigh
Answer: My personal answer is no way. 2 very skinny and exceptionally friendly people, perhaps. I carry a Texsport Saguaro in my sea kayak as an emergency bivy shelter and it serves that role very well. At these prices you could each have your own tent.
Question: Can this survival bag reused
Answer: I've used this tent in rain, sleet, hail and snow. Leaking has never been a problem.
Question: Would these be good for the homeless or would the sheeting be better
Answer: I still have mine since 2013 and i used it just about every weekend and so far no problems. You will love it

User questions & answers

Question: Is this a sleeping bag? The description is quiet elaborated so I’m confused if it’s a kit
Answer: It is a mylar emergency blanket in the shape of a sleeping bag. It is for emergencies, not in place of our addition to a sleeping bag.
Question: Is the sleeping bag make crunch noises
Answer: It is mylar, and mylar does make some sound when moving around on it. But mylar is absolutely the best emergency blanket/bivy material there is. Not something to use instead of a sleeping bag for camping, but the best thing you can keep around for emergencies.
Question: is this bivvy moisture-wicking
Answer: No. Temporary or emergency use only. Similar to what is utilized by the military or EMT personnel.
Question: Has anyone used it with a sleeping bag for extra warmth? I always freeze camping
Answer: If you freeze camping you need a warmer bag or more likely a warmer sleeping pad. A good sleeping pad will do more for warmth than any other piece of equipment. You can also add a sleeping bag liner, Alps makes an inexpensive one. A liner can add 5 to 10 degrees to your bags rating. You either sleep cold or warm when sleeping outdoors; if you are warm in a 35 degree bag when it's 35 degrees outside you sleep warm. Woman sleep colder than Men. A 20 degree bag for a Man might be comfortable for a Woman down to only 35.
