This down would solely be capable of soak up about 20% of the water. Very spectacular.

Disclaimer: I don’t suggest 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 along with your higher physique. They do job of stopping any down from shifting throughout the night time. If you’re a aspect sleeper or transfer round loads throughout the night time, meaning this design will work effectively for you.

If you endure from actually chilly toes Zpacks have you ever lined with their Goose Down Socks.

Overall, 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 the very best.

Zips and Draft Tube

The Zpacks Mummy Sleeping Bag is the latest 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.

Along the zip, there’s a size of inside webbing that’s each light-weight and adequate sufficient to stop most snags. If you attempt laborious sufficient you’ll snag the zip however in most conditions, it really works effectively.

Along the size of the zip and there’s a draft tube which does job. There is not any draft tube across the collar or the hood like many different sleeping baggage. But the bag nonetheless appears to do an satisfactory job of retaining the heat in.

Hood

The hood on the Zpacks Mummy Bag may be very primary in design and performance. There is not any draft tube across the hood or collar however the primary design appears to do job of retaining the warmth in.

The stuff sack doesn’t use compression straps. You can sit on the stuff sack after placing the sleeping bag inside. This will take away the air and can lower the dimensions 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.

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 additional room, you’ll be able to think about the broader width. Check the web site for the precise specs.

Overall, the sizing of the bag is nice and precisely as talked about on the specification sheet on their web site.

Warmth

Zpacks don’t check their baggage to EN or the newer ISO 23537 Standards. They use their very own temperature scores primarily based on their very own expertise. They estimate the temperature scores to be near the ISO Rated ‘Limit’ Rating of a Sleeping Bag, which is typically known 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. But judging from the quantity of down used within the bag, mixed with the 900 loft, and the standard of the baffles, I’d consider that the 10F and 20F scores needs to be fairly near the restrict/transition scores for most individuals.

Zpacks don’t present a lofting bag, which is one factor that could possibly be improved. When storing your Zpacks sleeping bag it’s best to not go away it compressed contained in the stuff sack. Extended durations of doing this may have an effect on the lofting capacity of the down. The increased high quality of the down (the upper the loft quantity, eg 900) the extra likelihood it’s important to harm the down over an prolonged time period.

I strongly suggest storing your sleeping bag in a bigger lofting bag to extend the size of service of your bag. If you do that, you’re going to get no less than 10-20 good years of use out of this bag. Especially in case you deal with it and wash it when wanted.
