How to Choose The Best Cold Weather Sleeping Bag

There are things to consider before purchasing a sleeping bag, such as insulation type, shape and provided features. Below we will briefly cover each one of them, but if you would like to know more about sleeping bags, make sure to look at our comprehensive article about different types of sleeping bags.


Shape

Sleeping bag shapes

Rectangular Sleeping Bags: They are more comfortable than other types of sleeping bags since they provide a great amount of space in the sleeping bag, but they are less efficient for warmth.

Mummy Sleeping Bags: Due to their tapered form they surround the user’s body, therefore, they provide more warmth. Since mummy sleeping bags have less fabric they are lighter but less comfortable than other types of sleeping bags.

Semi-Rectangular Sleeping Bags: They have a tapered form as well, but they are not as narrow as mummy sleeping bags at the bottom. For warmness, they are more efficient compared to rectangular sleeping bags, and they are more comfortable compared to mummy sleeping bags.

Double Sleeping Bags: This type of sleeping bag is made for two-person. They are perfect for camping with your partner.


Insulation

There are two types of sleeping bags when it comes to insulation which is down and synthetic.

Down: Insulation material for down sleeping bags is simply the down of goose or duck (the feathers which keep the egg warm). Down sleeping bags are much lighter and more compressible than synthetic sleeping bags, therefore they are the best type of sleeping bag for backpacking. They are generally more expensive than synthetic sleeping bags due to their warmth to weight ratio and compressibility. The most important thing to look for when purchasing a sleeping bag is fill-power. Fill-power represents the quality of the down insulation. Greater the fill power, the more “warmth to weight ratio”, you will get.

Synthetic: The second type of insulation for sleeping bags is synthetic. They are heavier and less compressible than down sleeping bags, therefore, they are more affordable than down-insulated sleeping bags. The biggest advantage of synthetic sleeping bags is they don’t lose their effectiveness in damp conditions as well.


Features

Cinchable Hood: Some sleeping bags have drawstrings on the hood, that feature allows the user to cinch the hood down to keep the heat inside. So look for a sleeping bag that has drawstrings to feel warmer in cold nights.

Hyke and Byke Snowmass 0

Zipper’s Heat Loss Protection: A sleeping bag’s weakest spot is the zipper area when it comes to heat loss. Therefore most of the quality sleeping bags provide a draft tube or a baffle behind the zipper to reduce the leat loss through it.

Two Way Sliders: Even though sleeping bags are made for protection from the cold, sometimes inside of the sleeping bag might be too warm. To obtain the optimum temperature some sleeping bags provide two-way sliders. With two way sliders, you can unzip the bottom of the sleeping bag for ventilation while keeping the upper area zipped.

Inner Pocket: It is not the most important feature to look for, but some sleeping bags provide an inner pocket to keep your valuables from the cold.
