Like a lot of the Zpacks sleeping bag vary, it is available in 4 colours, specifically inexperienced, blue, black, and my private favourite orange.

On this overview, 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 mean time it solely comes within the 10F and 20F temperature rankings. I used and examined the 10F for this overview however the data introduced can even be related to the 20F model.
There are a number of options that set this aside from a lot of the different ultralight sleeping baggage and quilts available on the market.
Firstly, it has a full zip that permits the bag to be utterly unzipped and used as a quilt.
Secondly, it’s overstuffed by 30% further 900 loft water resistant down. I really like this characteristic. It means that you can use the bag extra occasions than most different baggage earlier than it must be washed. Excellent for the long-distance thru-hiker.
And thirdly, Zpacks have been capable of produce a high quality sleeping bag that’s heat, ultralight, and has best-in-class versatility.
When in comparison with different ultralight sleeping baggage, the full-length zip elevated the load of this mummy sleeping bag barely. However the skill to make use of the bag in a extra different vary of temperatures and conditions appears to be compromise.
The anti-snag zip labored properly because of a strip of webbing that runs the size of the zip, and the draft collar does an honest job of stopping drafts from coming into.
The Zpacks Mummy Sleeping Bag comes with an outsized Dyneema stuff sack. Not solely is the stuff sack waterproof however the giant measurement makes it simple to pack up the bag within the morning. Though the employees 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 capable of cut back the pack measurement by half when utilizing this system.
General, the model new Zpacks Mummy Sleeping Bag is the most effective full zip mummy sleeping bag for 2023. The flexibility of this mummy bag permits it for use as a backpacking quilt and is bound to be highly regarded on thru-hiking trails world wide in 2023 and past.
Down sort / fill energy

That is proper up there with among the highest quality down used on any sleeping bag in the mean time, 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. With 30% further down within the baffles it permits the bag to do a greater job at staying lofted in tough conditions comparable to damp climate, or when your bag could be very properly used comparable to on a thru-hike.
When your bag is soiled, soaked with weeks and months of sunscreen, physique oils, and extra it can lose numerous its loft and never be as efficient at protecting you heat. The additional 30% of fill will guarantee most loft when different baggage are beginning to lose their loft. Through-hikers who would possibly use this bag for 100-150 nights earlier than washing it can love this characteristic.
Like virtually each sleeping bag available on the market proper now, the goose down is Responsibly Sourced and Accountable Down Commonplace Licensed.
Building
Let’s take an in-depth have a look at how the Zpacks Mummy Sleeping Baggage are made with the options such because the Interior and Outer Shell materials, zippers, baffles, draft tubes, hood, and climate resistance.
Outer and Interior Shell material
The exterior face material and inner liner of the Zpacks Hooded Mummy Sleeping Baggage are made utilizing a 7 Denier Ripstop Ventum Nylon. This is without doubt one of the lightest materials used on any sleeping bag that you could purchase in 2023.
It’s coated with a PFC-free DWR coating to stop drops of water from coming into the bag. Once you check out this material 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 material. I examined the water resistance and high quality of the DWR coating. Whereas I didn’t sleep outdoors in rain I poured a number of liters of water on the sleeping bag, and I can affirm it can present an honest degree of water resistance.
The Zpacks Mummy Sleeping Bag could be ok to sleep outdoors beneath the celebs 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’ll be able to see from the picture under once I examined the DWR coating on the material, the water beaded fairly properly. It’s going to get in by means of the stitching and the place the zips are however it’s reassuring to know that Zpacks use water resistant down. This down would solely be capable to take 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 outdoors 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 along with your higher physique. They do job of stopping any down from shifting in the course of the night time. If you’re a facet sleeper or transfer round quite a bit in the course of the night time, meaning this design will work properly for you.
The decrease part makes use of horizontal baffles. These kinds of baffles do job of locking in as a lot warmth as attainable. The horizontal baffles at your ft will not be sewn by means of to maximise the loft and heat to your ft. In the event you endure from chilly ft then you’ll like this design.
In the event you endure from actually chilly ft Zpacks have you ever coated with their Goose Down Socks.
General, there may be 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 the most effective.
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 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 onerous sufficient you’ll snag the zip however in most conditions, it really works properly.
Alongside the size of the zip and there’s a draft tube which does job. There isn’t a draft tube across the collar or the hood like many different sleeping baggage. However the bag nonetheless appears to do an satisfactory job of protecting the heat in.
Hood
The hood on the Zpacks Mummy Bag could be very fundamental in design and performance. There isn’t a draft tube across the hood or collar however the fundamental design appears to do 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 concern.
The toggles are light-weight and fundamental however work properly. When sleeping in your facet, abdomen, or again the hood stays in place and performs properly.
General, the hood is inferior to another sleeping baggage however the hood is heat and the fundamental design does the job of protecting the general weight of the sleeping bag as gentle 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 simple to pack the bag within the morning. No must attempt 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 possibly can 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 measurement. After sitting on the bag, do up the clips, and it’ll pack to a small measurement.
The picture under doesn’t do justice to only how small the 10F sleeping bag can compress. It could go smaller than the picture under! Nice for the times whenever you want all of the room attainable inside your ultralight backpack.
Consolation
The Zpacks Mummy Sleeping Baggage 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 measurement, even when sporting an expedition spec down jacket. If you’re a bigger construct or need further room, you’ll be able to contemplate the broader width. Test the web site for the precise specs.
General, the sizing of the bag is nice and precisely as talked about on the specification sheet on their web site.
Heat
Zpacks don’t take a look at their baggage 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 known as the ‘transition’ score.
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 might imagine that the 10F and 20F rankings must be fairly near the restrict/transition rankings for most individuals.
Caring on your Zpacks Mummy Sleeping Bag
The Zpacks Mummy Sleeping Bag just isn’t the most cost effective sleeping bag available on the market, so it’s value caring for it. Among the finest issues you are able to do is put on clear backpacking base layers to mattress to stop sweat, filth, and physique oil from penetrating the liner of the sleeping bag. It’s also possible to use a sleeping bag liner to maintain it clear.

Zpacks don’t present a lofting bag, which is one factor that might be improved. When storing your Zpacks sleeping bag it’s best to not depart it compressed contained in the stuff sack. Prolonged durations of doing this may have an effect on the lofting skill of the down. The upper high quality of the down (the upper the loft quantity, eg 900) the extra probability you must harm the down over an prolonged time frame.
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’ll get no less than 10-20 good years of use out of this bag. Particularly for those who handle it and wash it when wanted.
