More than just a bed, the sleeping bag will protect you during a night out in nature. Feeling cold in the middle of the night or even dying of heat to the point of not letting you sleep does not mean that you did not buy a good sleeping bag but rather that you bought the wrong bag… For being a key item, Choice is imperative.
And for that, you need to take into account a number of details and tips, which we listed below.
But before that, it is important that you consider how you intend to use your equipment, on what occasion and situation, etc. Are you going to camp near the car? Will you use it in wild encampments and therefore need to carry it inside the backpack? Do you only camp on beaches and in warm places?Need a ‘multi-function’ outfit that turns a duvet into the beach house or wants a sleeping bag that supports negative temperatures?
Before buying a sleeping bag, a good rule of thumb is to think about the cooler night you are going to have to deal with, and then go down about 5 degrees Fahrenheit. Remember that it is harder to stay warm in a sleeping bag made for warmer temperatures than cooling in a sleeping bag for colder temperatures-a fully opened zipper usually solves this problem in a matter of seconds.
Some situations of using the sleeping bag:
Camping – being very close to the car, the weight and the volume are not significant, being able to choose models that offer more comfort, like the rectangular ones that, open, they saw a great duvet.
Trails-will be carried in the backpack by trails that may require one to several overnight stays. The volume to weight ratio should be much lower than the equipment used in the campsite.
Expedition-in addition to being carried in the backpack, they demand a high performance and will be chosen according to the region to be visited, and can vary between -15oC to -50oC (top of the line in the world, with very few users. Not even Everest demands such a powerful bag).
Details to consider before buying a sleeping bag:
1-Format-There are two main formats of sleeping bags: a – Camping-are the rectangular ones. They usually open entirely, becoming a duvet. Some come with a hood, which facilitates in colder places but, in general, are bags for hot places, because the larger opening lets out the heat more easily. For those who are a little claustrophobic or get a lot of moves at night, these models are the most indicated. B-Mummy-accompanies the shape of the body and heats better, in addition to being lighter and more compact. All of these Tracks & Rumos bags have zippers and allow them to be made into a double bag (make sure you have bought zippered bags on opposite sides so they can come together).Some come with compressor tapes to shrink when stored.
2-Temperature-In addition to the name, what differs from the models is the minimum temperature at which it allows you to sleep comfortably inside it-this is not an exact science and you will only effectively see the difference between bags from the same manufacturer. Some factors should be taken into account, such as tiredness, the presence of wind, hunger, humidity and personal factors, since there are hot and cold people (generally people with lower blood pressure and body fat tend to feel colder) . The temperatures indicated on the sleeping bag package give a measure of comfort, but you must always consider some margin, you can say that our indications serve about 80% of people, always remembering that the use of an insulated mat together is indispensable , Since the body weight reduces the insulating efficiency of the fibers under the weight of the body. In the packaging the temperature is defined as comfort, tolerance and extreme. “Comfort” is the temperature at which you will feel good in the sleeping bag without the use of very heavy clothes. “Tolerance” indicates that it would be necessary to be dressed in the same type of warm clothing that you would wear outdoors at that temperature (when we sleep or are inactive, we need more protection from the cold). And “extreme” indicates that it is necessary to wear extra warm clothing to feel comfortable yet at the temperature indicated inside the sleeping bag. Try to lie down fed by a hot meal and you will have a better night. And most importantly, try to have a sleeping bag a little longer than the minimum temperature you plan to face. If you use your sleeping bag wrapped by a blanket or an emergency aluminum bag (ref 8235, Coghlan’s), its thermal insulation improves by up to 5 ° C, also protecting it from moisture. The emergency blanket is a useful and inexpensive accessory that should not be missing inside backpacks…
3-Thermal collar and hood-we lose at least 25% of the heat by the head and to keep you warm, our sleeping bags have hoods that close enough to allow you to breathe but do not let the heat generated by your body leave .The thermal collar prevents heat from the body from escaping through the opening in the neck area, keeping your body warm. It is worth remembering here that all equipment for cold does not “manufacture” heat, but have the function of not allowing the heat produced by the body itself to dissipate, thus maintaining its thermal comfort. These items usually do not exist in rectangular sleeping bags, but are essential in bags that withstand low temperatures.
4-Hot seams-seams can be an important way to lose heat, through the micro holes made by the needle. Thus sleeping bags for colder temperatures have “mismatched” seams between the inner and outer layers, not allowing the hot air to escape.
5-Zipper-the zippers should be easy to handle and open to both sides.Remember that you may have to handle them with gloves on cooler nights. Sleeping bags designed for lower temperatures will have a ‘flap’ between your body and the zipper, so you do not allow your heat to go out there. Some of the sleeping bags in the Tracks&Rumos line have seen a double bag just by joining the zippers, which must be on opposite sides. You should check this BEFORE you buy them…
6-External and internal fabric-normally, are made of nylon/polyester (external) and tactel or microfiber (internal). The outer nylon is not treated with waterproofing because your body perspires a lot at night and this steam needs to come out somehow, so as not to condense inside the bag and end up wetting it.
7-Filling-here is the difference of most sleeping bags… here is how much a sleeping bag supports temperature. The air is the biggest insulation we have and the ability of the fibers of the filling store air is what will make it more or less hot. The fibers can be natural (goose chiffon feather-duvet or down-and wool) or synthetic. Synthetic fibers come in various shapes and names, according to their manufacturer, and seek to ‘mimic’ the insulation and compression capability that the goose feather offers. However, the goose feather does not work when wet, takes time to dry (and drying is the most delicate part of goose feather use), and maintaining a sleeping bag made from this material is quite delicate. In addition, it usually has a shorter service life than synthetic fiber. This, in turn, is heavier than the feather, but still keeps the heat even wet, dries faster and maintenance is a little easier, but still requires some important care (see the next Tips for Use). The technology that exists behind synthetic fibers does not stop improving, making them ever closer to the goose feather in weight, heating capacity and compression. One of the ways to measure the thickness of the synthetic fibers is through the denier. A hair has 20 denier, for example. The larger the number, the thicker the yarn. The basis for this research was sheep’s wool, and today synthetic fibers seek to imitate it. Fibers thinner than a hair and with one, four or seven holes in each of these filaments. Fine fibers, infinitely thinner than a hair, creating a tangle of yarns that can be compressed and back to normal, and create pockets of air that make them very efficient. Short or long fibers, fiber shape, shape and size of holes within the fibers. Density, weight and thickness. The manufacturers can create and vary a lot on these issues and who wins is you!
The news that Trails & Rumos, always attentive, brings you! -Trilhas & Rumos is bringing a revolutionary fiber called Micro-Tec to Brazil. Micro-Tec is a recent evolution of insulating fibers, made of micro filaments of only 0.7 denier, that manages to retain more air, similar to the one obtained with goose feathers. Some properties of this fiber: warm even wet, do not retain so much water, which lets it dry faster than other fibers, and have a good thermal insulation with less volume, resulting in a much more compact sleeping bag for transport.
Another great novelty that Tracks&Rumos brings to you is the ‘loose-shell’, which means that this sleeping bag will not have seams on the front and back, to avoid heat loss through the micro-holes made by the needles. seam. The filling of the bag is covered by a layer of fine insulation fabric and attached only to the sides
