Things to Consider When Buying the Best Sleeping Bag for Warm Weather
Like all other products, buying for the best sleeping bag for warm weather involves different factors for consideration. Below are the things that might generally affect your buying decision.
1-Temperature Rating
As you can observe, all of the sleeping bags here on the list has temperature rating. Actually, this aspect is highly important as it tends to be the legal standard for sleeping bags which was developed by the European Advisory. This aspect was adopted eventually by numbers of countries around the world in which some may use the term “comfort level”.
Generally, the term temperature rating or comfort level for sleeping bags describes the lowest possible temperature that the bag is made for. The said temperature can able to withstand by the sleeping bag prior to the average individual will feel cold. Usually, most sleeping bags show the EN or European Norm Lower Limit which is equivalent to 10 to 15 degrees lower than the EN Comfort Rating.
However, when you decide to choose the appropriate temperature rating for the sleeping bag, there is no exact science to use for it. Keep in mind that there are lots of factors affecting the warmth inside the sleeping bag. These factors generally include the clothing of the individual, sleeping pad insulation, altitude, hydration, and nutrition.
Increasing Temperature Rating
Additionally, there is also the so-called increasing temperature rating that comes in the sleeping bag. This is also a crucial thing to remember when buying warm weather sleeping bags. Always remember that you can basically elevate the warmth inside the sleeping bag most of the time by adding extra layers.
For instance, a jacket with a hood will relatively increase the warmth inside the sleeping bag as you will sleep with it. Wool base layers, gloves, or warm hats will also basically contribute to achieving extra warmth. You may also consider eating prior to getting inside the sleeping bag or keeping yourself well hydrated. Moreover, placing hot water inside the sleeping bag on the feet will also do the trick.
2-Season Rating
Aside from the temperature rating, sleeping bags are also described in terms of the season ratings. Well, this aspect tends to be a simpler one as you will have to check the following codes for the ratings:
| Rating | Season Condition | Temperature |
| Season 1 | Summer | +5 degrees and above |
| Season 2 | Spring / Summer | +0 degrees |
| Season 3 | Spring / Summer / Autumn | 0 to -5 degrees |
| Season 4 | Year-round | -12 degrees and lower |
| Season 5 | Extremely cold | – |
Based on table, it only shows that camping on hot places would generally necessitate you to go for Season 1 or Season 2 rating.
3-Material
The material of the sleeping bag and even of any camping gear dictates if the gear really fits in your purpose. Generally, in the market, majority of the sleeping bags come with either synthetic fabric or down. Comparing the two, a synthetic sleeping bag is the ideal sleeping bag of choice for going into hot places. This is due to the less insulation feature that it has compared to that of the down.
Additionally, the synthetic type of material for sleeping bags is actually budget-friendly and requires lesser care and maintenance. In terms of the down sleeping bags, this type tends to be more compact than the synthetic one. Moreover, down sleeping bags are also light in weight making it comfortable to carry along.
The fabric lining is also an added consideration here. Flannel linings basically have high insulating capabilities making it undesirable for hot weather conditions. With that, great alternative would be light and breathable materials like the cotton. You may also consider using a silk sleeping bag liner which offers incredible coolness during an extreme hot weather.
4-Shape, size, and weight
Generally, the sleeping bags have different shapes and sizes. Along with this is the variation in weight. There are two most common shape types of the sleeping bags. These are the envelope-shaped or also known as the rectangular and the mummy-shaped or the tapered sleeping bags.
MUMMY-SHAPED SLEEPING BAG
From the name itself, the mummy-shaped sleeping bag basically fits around the body and makes you look that you are mummified. This sleeping bag is usually tapered which provide better retention of heat. The mummy-shaped sleeping bag also has a lesser weight compared to the other type.
Moreover, this bag also features a stuff sack having a drawstring and toggle. The purpose of such accessories is to allow the bag to get compressed. That’s the reason why the mummy-shaped sleeping bag tends to be an ideal one for backpacking as it is much easier to carry. So, it is better to go for this type of sleeping bag when you want to pack an ultralight backpack.
ENVELOPE-SHAPED SLEEPING BAG
Also known as the rectangular sleeping bag, this usually comes with zippers along both sides. This generally means that the sleeping bag can be turned into a blanket due to its fully opened feature. Meanwhile, as it tends to zipped up, this envelope-shaped sleeping bag offers additional space for individuals to move around.
This sleeping bag also features a less insulating property that basically permits the movement of air. Yet, in terms of weight, this is actually heavier than the first type. Typically, the envelope-shaped sleeping bag does not include a compression sack making it bulky to carry. Because of that, using this for backpacking is a no-no.
*Which sleeping bag shape is better for warm weather?
Well, warm weather backpacking usually necessitates you to choose a mummy-shaped sleeping bag that has the lightweight feature. Make sure that it compresses in a smaller size and made with a full-length zipper to have better ventilation especially during extremely warm weather. Moreover, you can also consider using an envelope-shaped sleeping bag provided that it is also lightweight and has a stuff sack to avoid bulkiness.
5-Zipper
Sleeping bag zippers also need to take some things for considerations. These are the following:
- Left or right-handed zipper – having the appropriate zipper will allow an individual to easily hop out from the bag at night during an emergency. A left-sided zipper is generally ideal for right-handed backpackers and vice versa.
- Two-way zipper – this sleeping bag is highly ideal for warm conditions because it produces extra ventilation.
- Half-length or full-length zipper – warm weather sleeping bags with full-length zipper is the perfect one for hot places due to its feature of fully opening up the bag and allowing the heat to get out from the inside.
6-Length
Moreover, you should also consider the length of the sleeping bag as it should fit in your height. Being on the edge means that you will have a better fit if the size of the sleeping bag is longer.
7-Price
Obviously, this has something to do with your set budget. So, it is better to check on its price carefully and always go for the one that you can generally afford.
8-Personal Preference
Since we are all different individuals, we also have different tolerance when it comes to the weather or temperature. There are some who can able to take the heat compared to others. That’s why this factor should also be taken into account when buying a sleeping bag for warm weather. Check on the individual’s ability to deal with the heat.
In case you are comfortable working in warm conditions, better to consider this factor and choose the Season 2 sleeping bag. Moreover, in terms of gender, women have the ability to feel the cold easier than men. Additionally, women also have lower body temperature during the night. This means that female campers or backpackers should go for a slightly warmer sleeping bag.
9-Durability
Some sleeping bags are treated with durable water repellent in order to make the water bead up into the outer layer. However, this kind of treatment will eventually wear off over time. With that, reapplication is needed. Perhaps, this is a great feature to consider. Although it doesn’t make the sleeping bag totally waterproof, it will still incorporate added protection.
10-Add ons
Sleeping bags with inner pockets are actually another thing to consider here. This is most likely true if you are staying within a hostel. The ideal location of the inner pockets should be on the top portion of the sleeping bag. This will generally offer security and safety of valuable items like cellphones or wallets.
