ZPacks™ 900 Fill Power Down Sleeping Bag

Rated this product ⭐️⭐️⭐️⭐️⭐️ because it is lightweight, warm and versatile. I get quite cold at night so tosssd and turned over going with the -7°C bag or the -12°C for the Appalachian Trail. Went with the -7°C in the end, as I use it here in Victoria Australia and figured a -12°C wouldn’t be that practical here.


Note the weight is going to be completely subjective as with most Z packs gear you can customize it, so depending on what you get will determine the weight of the item. 

I got the -7°C, Broad, X-long green sleeping quilt with default zipper and adjustable straps. Although I note that it looks like the adjustable strap option is no longer available.

I had never tried a sleeping bag/quilt before so wasn’t sure how it would go, but it has turned out brilliantly I like everything about my sleeping bag/quilt.


The bag opens up underneath you like a blanket for easy temperature control when it is warm out, and a 3/4 length zipper and neck elastic allow you to bundle up when the temperature turns cold.

I also use the adjustable straps, securing them under the mattress instead of the zipper when its not cold enough to be zipped in and not hot enough for the open quilt. 

I wasn’t sure how I would feel with the bottom of the sleeping bag/quilt being enclosed however it has been great. I get cold feet so this way they are snug and warm and for me, it makes it easier to turn over.


The reason I bought the extra long sleeping bag and I am quite pleased I did, is so I could pull the sleeping bag up around my chin as I do with my blankets. 

You should know that the goose down feathers do randomly come out of the sleeping bag when you use it for the first couple of times. This is actually quite normal for products containing feathers. 


So how warm is it? Well essentially that’s like asking how long is a piece of string. There are so many factors that go into keeping you warm at night; the temperature inside the tent, outside the tent, how much you feel the cold, what you’re wearing and the list goes on.

This is the best I can do to give you an idea: Camping on top of the Major Mitchell Plateau approx 1155m/3789f, nighttime temperature of  about 1°C/33f, slight breeze, tent closed down wore poly thermals, socks, rain pants and material hoodie – woke up bout 3am when the temperature went -0°C, but moved around vigorously inside the sleeping bag to warm up then drifted back off to sleep. 

I wouldn’t say I was toasty and after this trip bought heavier thermals, but I wasn’t so cold I couldn’t sleep, the temperature did push the limit of warmth and comfort for me though, without ‘rugging’ up more. Here is a shot of the frost inside the tent – so yep it was a bit on the cool side 😎

However my last camping trip in Little Desert (a couple of weeks ago) with nighttime temperatures down to approximately 5°C, wearing the poly thermals and light jacket, with the tent vestibule flaps open, and using the straps rather than the zipper, I was nice and warm. 

All in all very pleased with this purchase and would recommend 😊
