A sleeping bag is one of the most important pieces of kit you will take with you on your outdoor trip. But with so many sleeping bags on the market, it can be an overwhelming decision when trying to decide which one to buy. That is why I recently tested out the Winner Outfitters Mummy Sleeping Bag to give you an honest and in-depth review so you can see before you buy.

Key Features

There are many important factors to consider when buying a sleeping bag. Lets look at them in more detail:

3-4 Season

One thing I can say about this sleeping bag is that it is warm. Falling into the 3-4 season category, this means that the sleeping bag can withstand autumn/winter weather which includes frost and light snow. This is backed up by the temperature rating of 35°F to 40°F. I was using this sleeping bag in my camper-van during a winter trip where the temperature was as low as 30°F and it kept me warm throughout the night.

Insulation

The insulation for this sleeping bag is synthetic compared to down. This is often regarded as the inferior insulation as it is typically  heavier and not as warm as down sleeping bags. However, in terms of performance, this Mummy Sleeping Bag uses a special quilting system that prevents cold air from getting inside. In my opinion, it does just fine with the synthetic insulation which is made up of 200g of Hollow Fibre filling.

On a side note, I did notice that the stitching had come away on the inside of the sleeping bag, exposing the insulation underneath. This was unexpected as it has only been used around 10 times. I’m sure that I will have no trouble getting a replacement under warranty, though this is a slight inconvenience.

Outer Material

The sleeping bag outer layers consist of high-quality polyester, with a 350T polyester shell and lining. This, I found was soft and comfortable on the skin. The exterior is also water-resistant with a rip-stop cover. The water resistance was an important factor for me due to condensation in the van and the sleeping bag had no problems coping with it.

Size/Design

This sleeping bag measures 87 inches in length and is 32 inches wide. These fairly narrow measurements are usual for mummy-style sleeping bags and are great for containing body heat. The lower part of the bag is also box-shaped allowing for more movement. The hood pulls over the head and has an adjustable draw-string which kept my head warm during particularly cold nights. Another great feature is the snag-free double zip made by SBS which, according to the description, is one of the best zipper suppliers in the world. I had no problems zipping and unzipping the sleeping bag and experienced no snagging as promised.

Weight

This is a super lightweight sleeping bag, weighing just 2.8lb. This makes it a great choice for hikers and campers looking for a portable lightweight sleeping bag that is still warm enough to handle cold temperatures. The sleeping bag comes with a compression sack plus an extra carry bag which is handy. When packed into the stuff sack (total weight is then 3lb) it compresses the sleeping bag down to 9.8 x 8.5 x 8.5 inches.

Machine Washable

This is a great feature of the Winner Outfitters Mummy Sleeping Bag . The ability to machine wash the sleeping bag is so convenient, especially when it has been in use for a longer camping trip. It is also very quick to dry after it has been washed.

5 Year Warranty

If you are not satisfied with this sleeping bag, Winner Outfitters offer a 5 year limited warranty should there be any problems (such as the stitching with the one I own).

Price

This sleeping bag is definitely on the lower end of the scale price-wise. Though there are definitely cheaper brands, you are unlikely to find one as compact and insulated as the Winner Outfitters Mummy bag. There are also more expensive brands which would be more suitable for hikers looking for super lightweight sleeping bags or people camping in severely cold conditions. Overall, I think the cost is very compatible with the durability, weight and insulation of this bag.

A Few Downsides

Like most products, there are a few negatives to take into account, however, many of these are personal to me and may not necessarily be a problem to other campers.

The main downside for me was that I had a lot of trouble trying to stuff the sleeping bag back into the sack. It certainly wasn’t an easy task compared to other sleeping bags that I have had in the past. Granted, most sleeping bags are difficult to roll up into a tiny shape and stuff so this really is a small issue. If I was hiking, I would resolve this issue by just ditching the sack and stuffing the sleeping bag straight into my backpack.

Another small thing I would change is the zip length. In the past, I have used sleeping bags that zip all the way down, which is great for turning the bag into a blanket if you don’t want to be constrained. Having a zip all the way down also provides ventilation which is quite important for me as my feet get very hot and this would have alleviated some of that discomfort.

Overall score:

How Does It Compare To Other Sleeping Bags?

Sleeping Bag by Canway

The main difference with this sleeping bag by Canway is the shape. Unlike the Winner Outfitters Mummy Sleeping Bag, the Canway one is rectangular in size (measuring 82.7 inches by 31.5 inches) which means there’s some extra space for movement. It’s built with flannel inside to provide that warm and cozy feeling and protect you from a chilly night.

In terms of warmth, this sleeping bag can withstand similar temperatures, the lowest stated as 30°F.

For a similar price, this sleeping bag is definitely a contender.

Conclusion

For a mid-range sleeping bag, the Winner Outfitters is definitely a good investment that certainly lives up to expectations when it comes to keeping warm. I was disappointed that the stitching came away so easily, but I will put this down to a one-off and assume that my replacement will not have this problem. The 5 year guarantee is great for things like this.

All in all, a good sleeping bag that was comfortable, warm, dry and compact.
