Sleep is a necessity – a sleepless night can result in fatigue and a low mood the next day. If you’re hiking, mountain climbing, or doing any other activity that requires focus and energy, then you’ll need to make sure you sleep well.
Temperature greatly affects the way we sleep – if we are too cold, we may not get any sleep at all. This is why we must have a warm sleeping bag when sleeping outdoors.
The best winter sleeping bag will keep you both warm and dry in cold conditions, and ensure you have a cosy night’s sleep.
We are going to review 5 of the best winter sleeping bags, and include a guide that will help you decide which sleeping bag is best for you.

How to Choose the Best Winter Sleeping Bag
It can be hard to know what to look out for when choosing a sleeping bag that’s right for you, so we’ve created a guide that will help you come to your decision.
A down-insulated sleeping bag is great for keeping you warm while weighing less.
It compresses well, making it portable and easy to carry around with you on your adventure.
The most common types are duck down and goose down, and both are as good as each other when it comes to insulation.
The loft of down creates lots of little air pockets, meaning that the warm air will be trapped and retained.
Down-insulated sleeping bags are best for cold and dry environments, as any moisture can make the feathers lose their insulating properties.
Synthetic bags can be cheaper, but tend to be heavier and have a larger pack-up size.
1 Season – These sleeping bags are super lightweight and it’s best to use them in warmer summer months, or when camping in hot climates.
2 Season – It’s best to use 2-season sleeping bags in early autumn or mild spring months – most sleeping bags you’ll find in supermarkets tend to be 2-season.
3 Season – These sleeping bags can be used in spring or late autumn – maybe even milder winter days. These are recommended for kids going on school trips or short-term stays.
4 Season – These sleeping bags are thick and usually super insulated. They are made for use in winter when temperatures can be sub-zero.
5 Season – These, as you can imagine, are super thick and known as expedition bags. Most mountain climbers use this type of sleeping bag, as they’re perfect for extreme cold temperatures.
Shape and Size
Square sleeping bags are just standard, basic sleeping bags. There’s wiggle room, and can come in double size.
They don’t do much to protect you from the cold, so bare this in mind when choosing the best winter sleeping bag for you.
Mummy sleeping bags are shaped how you’d picture a mummy being mummified.
Wider at the top and tapered at the bottom, this design of sleeping bag will keep warm air inside the bag and close to your body, without circulating around the bag and cooling down.
They’re perfect for use in sub-zero temperatures, and are usually super comfortable.
A lot of sleeping bags have pockets in the interior. This is great for storing valuables such as phones, watches or wallets.
A draft collar is just a tube of insulation that drapes over your chest and neck, sealing in the bags warmth. This is a cold-weather essential when choosing the best winter sleeping bag for you.
Insulating the collar of the sleeping bag will ensure that your body heat doesn’t escape via the top of the sleeping bag. Most draft collars will have an adjustable pull cord to tighten when needed.
A lot of your body heat is lost through your head, so when sleeping in colder climates, you’re best off keeping your face and head nice and toasty.
A shaped hood will help keep in the heat, and those with a drawcord closure allow you to tighten the hood to trap in the warmth.
In sleeping bags, perspiration can get trapped in the down or on the outside of the tent, which reduces the sleeping bags ability to insulate heat.
The last thing you need when trying to sleep in a sleeping bag in the winter is for the inside of your bag to be frozen. This is why it’s best to choose a waterproof sleeping bag made with water resistant fabric.
You may opt for a partial length zipper. This is great for saving weight, but can limit the ventilation inside the bag.
A snag free zipper prevents the side zipper’s teeth from tearing the fabric. If the fabric gets torn, it will spill all the insulation. The zipper is usually bordered by a stiffer fabric, which won’t tear easily. The best winter sleeping bag will have a snag free zipper.
Sleeping bags are essential for survival outside. Winter sleeping bags should be equipped with insulation, and waterproof features to help you brace the cold weather.
We decided that the best winter sleeping bag is the OmniCore Designs Multi Down Mummy Sleeping Bag.
This bag will keep you toasty in the coldest of conditions, and is thoroughly testing using a third party lab.
The 3-D foot box reduces tension in your feet, which is perfect if you’re a hiker or if you’ve been on your feet for a while.
The foot box will also keep your feet warm. Our feet play a big part in regulating our overall body temperature, so if your feet are warm, the rest of your body will warm up.
Thanks for reading. Hopefully now you’ll be able to choose the best winter sleeping bag for you!
