On this assessment, I attempted the usual width and located it to be an ideal width that allowed me to maneuver round contained in the sleeping bag with out feeling cramped.
In the meanwhile it solely comes within the 10F and 20F temperature rankings. I used and examined the 10F for this assessment however the info introduced can even be related to the 20F model.

Firstly, it has a full zip that enables the bag to be fully unzipped and used as a quilt.
Secondly, it’s overstuffed by 30% additional 900 loft waterproof down. I like this characteristic. It permits you to use the bag extra instances than most different luggage earlier than it must be washed. Good for the long-distance thru-hiker.
And thirdly, Zpacks have been in a position to produce a top quality sleeping bag that’s heat, ultralight, and has best-in-class versatility.

Not solely is the stuff sack waterproof however the giant dimension makes it straightforward to pack up the bag within the morning. Though the workers sack is sort of giant, it may be compressed fairly a bit by sitting on the stuff sack to push the surplus air out of the stuff sack. I used to be in a position to cut back the pack dimension by half when utilizing this system.
Total, the model new Zpacks Mummy Sleeping Bag is one of the best full zip mummy sleeping bag for 2023. The flexibility of this mummy bag permits it for use as a backpacking quilt and is certain to be extremely popular on thru-hiking trails world wide in 2023 and past.
Down kind / fill energy

That is proper up there with a number of the very best quality down used on any sleeping bag in the meanwhile, only a few are utilizing a better loft than 900 fill energy.
What makes this sleeping bag higher than a lot of the competitors is the overstuffing of the baffles.

When your bag is soiled, soaked with weeks and months of sunscreen, physique oils, and extra it can lose a number of its loft and never be as efficient at protecting you heat. The additional 30% of fill will guarantee most loft when different luggage are beginning to lose their loft. Via-hikers who may use this bag for 100-150 nights earlier than washing it can love this characteristic.

Building
Let’s take an in-depth have a look at how the Zpacks Mummy Sleeping Luggage are made with the options such because the Internal and Outer Shell materials, zippers, baffles, draft tubes, hood, and climate resistance.
Outer and Internal Shell cloth
The exterior face cloth and inner liner of the Zpacks Hooded Mummy Sleeping Luggage are made utilizing a 7 Denier Ripstop Ventum Nylon. This is likely one of the lightest materials used on any sleeping bag you can purchase in 2023.
It’s coated with a PFC-free DWR coating to stop drops of water from coming into the bag. If you check out this cloth it’s virtually see-through and very light-weight.
Climate resistance
As talked about above, there’s a PFC-free DWR coating on the sleeping bag cloth. I examined the water resistance and high quality of the DWR coating. Whereas I didn’t sleep exterior in rain I poured a number of liters of water on the sleeping bag, and I can verify it can present a good degree of water resistance.
The Zpacks Mummy Sleeping Bag could be ok to sleep exterior underneath the celebrities when there’s a very small quantity of condensation in a single day. And as talked about above, the 30% overstuffing of down will help in protecting it as lofted as attainable.
As you may see from the photograph beneath once I examined the DWR coating on the material, the water beaded fairly effectively. It would get in by way of the stitching and the place the zips are however it’s reassuring to know that Zpacks use waterproof down. This down would solely be capable of soak up about 20% of the water. Very spectacular.
Disclaimer: I don’t advocate that you simply pour a complete bottles of water over your sleeping bag to check its water resistance nor sleep exterior within the rain!
Baffles
Zpacks use a mix of vertical and horizontal baffles.
The vertical baffles are used on the higher a part of the bag that corresponds together with your higher physique. They do a very good job of stopping any down from shifting throughout the evening. If you’re a aspect sleeper or transfer round quite a bit throughout the evening, meaning this design will work effectively for you.
The decrease part makes use of horizontal baffles. These kinds of baffles do a very good job of locking in as a lot warmth as attainable. The horizontal baffles at your ft usually are not sewn by way of to maximise the loft and heat to your ft. In the event you undergo from chilly ft then you’ll like this design.
In the event you undergo from actually chilly ft Zpacks have you ever lined with their Goose Down Socks.
Total, there’s little to criticize and plenty to reward with the baffle design, which mixed with the overstuffing of every baffle results in me regard this sleeping bag among the many better of one of the best.
Zips and Draft Tube
The Zpacks Mummy Sleeping Bag is the most recent addition to the Zpacks sleeping bag vary because it was solely launched in early 2023.
The zips and draft tubes work as anticipated and do a very good job.
Alongside the zip, there’s a size of inner webbing that’s each light-weight and enough sufficient to stop most snags. In the event you attempt exhausting sufficient you’ll snag the zip however in most conditions, it really works effectively.
Alongside the size of the zip and there’s a draft tube which does a very good job. There is no such thing as a draft tube across the collar or the hood like many different sleeping luggage. However the bag nonetheless appears to do an ample job of protecting the heat in.
Hood
The hood on the Zpacks Mummy Bag may be very fundamental in design and performance. There is no such thing as a draft tube across the hood or collar however the fundamental design appears to do a very good job of protecting the warmth in.
The scale of the hood are beneficiant sufficient to have the ability to put on a beanie, down balaclava, or expedition-weight down jacket with out challenge.
The toggles are light-weight and fundamental however work effectively. When sleeping in your aspect, abdomen, or again the hood stays in place and performs effectively.
Total, the hood is inferior to another sleeping luggage however the hood is heat and the essential design does the job of protecting the general weight of the sleeping bag as mild as attainable.
Stuff Sack
The Zpacks Mummy Sleeping Bag makes use of an impressively light-weight Dyneema stuff sack. It’s waterproof and fairly giant. Having a big stuff sack makes it straightforward to pack the bag within the morning. No have to try to squeeze it in completely each time. Simply shove it in any manner you want and it’ll work.
The stuff sack doesn’t use compression straps. You may sit on the stuff sack after placing the sleeping bag inside. This may take away the air and can lower the scale of the packed-up sleeping bag to about half its dimension. After sitting on the bag, do up the clips, and it’ll pack to a small dimension.
The photograph beneath doesn’t do justice to simply how small the 10F sleeping bag can compress. It will probably go smaller than the photograph beneath! Nice for the times while you want all of the room attainable inside your ultralight backpack.
Consolation
The Zpacks Mummy Sleeping Luggage is available in three lengths and two widths. The widths are beneficiant and enough for most individuals to not really feel too cramped. I examined the usual width and located it excellent for my physique dimension, even when carrying an expedition spec down jacket. If you’re a bigger construct or need additional room, you may take into account the broader width. Examine the web site for the precise specs.
Total, the sizing of the bag is nice and precisely as talked about on the specification sheet on their web site.
Heat
Zpacks don’t check their luggage to EN or the newer ISO 23537 Requirements. They use their very own temperature rankings based mostly on their very own expertise. They estimate the temperature rankings to be near the ISO Rated ‘Restrict’ Score of a Sleeping Bag, which is usually referred to as the ‘transition’ ranking.
I used to be unable to check the bag in very low temperatures. So I’ll replace this part sooner or later. However judging from the quantity of down used within the bag, mixed with the 900 loft, and the standard of the baffles, I’d imagine that the 10F and 20F rankings must be fairly near the restrict/transition rankings for most individuals.
Caring to your Zpacks Mummy Sleeping Bag
The Zpacks Mummy Sleeping Bag will not be the most affordable sleeping bag in the marketplace, so it’s price caring for it. Among the finest issues you are able to do is put on clear backpacking base layers to mattress to stop sweat, dust, and physique oil from penetrating the liner of the sleeping bag.

Prolonged durations of doing this may have an effect on the lofting means of the down. The upper high quality of the down (the upper the loft quantity, eg 900) the extra likelihood it’s a must to injury the down over an prolonged time period.
I strongly advocate storing your sleeping bag in a bigger lofting bag to extend the size of service of your bag. In the event you do that, you’re going to get at the least 10-20 good years of use out of this bag. Particularly if you happen to care for it and wash it when wanted.
