Understand More About Cold Weather Sleeping Bags:
A Few Shapes That Sleeping Bags Come in
Barrel Sleeping Bags

Looking to purchase a new all-purpose sleeping bag? We have six barrel sleeping bags available. Click here to take a look at one now. With a super spacious design, barrel sleeping bags are ideal for those who like plenty of room to stretch out. They accommodate varying sleeping positions, making them ideal for people who are particular about sleeping in certain positions such as their sides or stomach. Barrel sleeping bags are a great compromise between the more fitted mummy shape and the roomier rectangular sleeping bags, so they are a great choice for something spacious while not compromising warmth.

Rectangular Sleeping Bags

Looking to purchase a new sleeping bag that will offer tons of room to stretch out? We have 133 rectangle sleeping bags available. Click here to take a look at one now. With a spacious design, these sleeping bags are ideal for those who like plenty of room to stretch out. They come with double zippers, making them very versatile, doubling as a blanket or attaching to another sleeping bag for combined body heat on extra cold nights. These sleeping bags accommodate varying sleeping positions, giving you plenty of room to get comfortable, regardless of your sleeping position. Something to consider is that they are quite heavy, so they aren't good for when weight is a concern. On top of that, they don't trap and heat the air around your body as well as other designs do, creating extra space inside which can weaken the bag's ability to keep you warm.

Mummy Sleeping Bags

Trying to pick the most suitable mummy sleeping bag for you? We will help you make an informed choice by providing you with the pros and cons. Mummy sleeping bags weigh less than rectangular bags, so they are best when you need maximum warmth and minimal weight. They create a snug and tight fit that helps seal in warmth, providing maximum warmth, since their tight fitting cut is designed to trap body heat. Something to consider is that they provide less space to move around, making them less suitable for sleepers who toss and turn. Decided on which shape is perfect for you? Then have a look at this fantastic product.

Which Size Best Suits Sleeping Bags

Single Sleeping Bags

If you're looking for a sleeping bag in single, then you should consider this great sleeping bag.
