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.

Firstly, it has a full zip that permits the bag to be fully unzipped and used as a quilt.

Not solely is the stuff sack waterproof however the giant measurement 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 scale back the pack measurement by half when utilizing this method.
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 highly regarded on thru-hiking trails world wide in 2023 and past.

Development
Let’s take an in-depth take a look at how the Zpacks Mummy Sleeping Luggage are made with the options such because the Inside and Outer Shell materials, zippers, baffles, draft tubes, hood, and climate resistance.
Outer and Inside Shell cloth
The exterior face cloth and inside liner of the Zpacks Hooded Mummy Sleeping Luggage are made utilizing a 7 Denier Ripstop Ventum Nylon. This is among the lightest materials used on any sleeping bag which you can purchase in 2023.
It’s coated with a PFC-free DWR coating to forestall drops of water from coming into the bag. If you check out this cloth it’s nearly 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 outdoors in rain I poured a number of liters of water on the sleeping bag, and I can verify it should present a good degree of water resistance.
The Zpacks Mummy Sleeping Bag could be ok to sleep outdoors below 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 preserving it as lofted as potential.
As you possibly can see from the picture beneath once I examined the DWR coating on the material, the water beaded fairly effectively. It’s going to get in via the stitching and the place the zips are however it’s reassuring to know that Zpacks use waterproof down. This down would solely have the ability to take in 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 a very good job of stopping any down from shifting through the evening. In case you are a facet sleeper or transfer round loads through 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 potential. The horizontal baffles at your toes aren’t sewn via to maximise the loft and heat to your toes. When you endure from chilly toes then you’ll like this design.
When you endure from actually chilly toes Zpacks have you ever coated with their Goose Down Socks.
Total, 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 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 inside webbing that’s each light-weight and enough sufficient to forestall most snags. When you attempt arduous 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 baggage. However the bag nonetheless appears to do an satisfactory job of preserving the heat in.
Hood
The hood on the Zpacks Mummy Bag may be very primary in design and performance. There is no such thing as a draft tube across the hood or collar however the primary design appears to do a very good job of preserving the warmth in.
The size 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 primary however work effectively. When sleeping in your facet, abdomen, or again the hood stays in place and performs effectively.
Total, the hood is inferior to another sleeping baggage however the hood is heat and the fundamental design does the job of preserving the general weight of the sleeping bag as mild as potential.
Stuff Sack

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 approach you want and it’ll work.
The stuff sack doesn’t use compression straps. You’ll be able to sit on the stuff sack after placing the sleeping bag inside. It will 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 beneath doesn’t do justice to only how small the 10F sleeping bag can compress. It could go smaller than the picture beneath! Nice for the times whenever you want all of the room potential 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 good for my physique measurement, even when carrying an expedition spec down jacket. In case you are a bigger construct or need further room, you possibly can contemplate 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 take a look at their baggage to EN or the newer ISO 23537 Requirements. They use their very own temperature rankings primarily based on their very own expertise. They estimate the temperature rankings to be near the ISO Rated ‘Restrict’ Ranking 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 might consider that the 10F and 20F rankings needs to be fairly near the restrict/transition rankings for most individuals.
Caring on your Zpacks Mummy Sleeping Bag

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 will 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 likelihood you must harm 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. When you do that, you’ll get a minimum of 10-20 good years of use out of this bag. Particularly when you handle it and wash it when wanted.
