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.
- Lightweight and compact
- Difficult to stuff back into compression sack
- Doesn’t zip all the way down
- Limited ventilation for feet
There are many important factors to consider when buying a sleeping bag. Lets look at them in more detail:
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.
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.
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.
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.
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.
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).
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.
How Does It Compare To Other Sleeping Bags?
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 82.6 inches by 31.5 inches) which means there’s some extra space for movement. It has a hollow cotton filling and the same polyester surface material (though 230T compared to Winner Outfitters 350T). It is comfortable, waterproof and lightweight (though a little heavier than the Winner Outfitters bag at 4.2lbs).
In terms of warmth, this sleeping bag can withstand similar temperatures, the lowest stated as 32°F.
They use a similar two-way zip system but unlike Winner Outfitters, they have an additional zip at the bottom of the bag so you can stick your feet out if they get too hot.
For a similar price, this sleeping bag is definitely a contender. They also guaranteed lifetime protection which is an added bonus and gives you that peace of mind should there be any issues years down the line.
Sleeping Bag by WhiteFang
This sleeping bag by WhiteFang shares many similarities with the Winner Outfitters sleeping bag – the shell and lining is 100% polyester (though 210T instead of 350T) and the temperature range is 35°F to 40°F (though it claims it keeps you warm even at 20°F for extreme use). It is waterproof, machine washable and it also uses the same brand of zipper. It measures the same in size but is a few pounds heavier (3.3lbs).
The main distinction that makes this WhiteFang sleeping bag stand out from others is the zippered openings for arms and feet. This means that you can do lots of tasks such as walking, reading or drinking tea without having to leave the comfort of your sleeping bag. A few downfalls are that it only has a 1 year guarantee and the bag looks very snug and may not be comfortable for larger people.
Priced at affordable range, this is a sleeping bag that is great for people that would benefit from the arm and feet holes.
Portable Mummy Sleeping Bag by BOS
This is a sleeping bag perfect for tall people (up to 7.2 feet in fact). It is slightly narrower than the Winner Outfitters sleeping bag (29.9 inches) and also heavier at 3.8lbs, though it comes with a travel-friendly compression sack perfect for backpackers. It uses the same polyester lining (190T) with a waterproof polyester shell and also showcases excellent stitch quality. It can keep you warm in extreme temperatures as low as 23°F and has has a 100% satisfaction guarantee.
A difference with this sleeping bag and the Winner Outfitters bag is the zip. As opposed to the double zip feature, the BOS sleeping bag has a 2-way zipper that allows you to connect it to another sleeping bag in the same range if you prefer a double sleeping bag.
Coming in at the same price as the Winner Outfitter’s sleeping bag, this is another good option to consider.
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.
