Great sleep! Lightweight
This is the best sleep system I have used, great for backpacking. Add in a NXT Air and it is a winning combination. Slapp in size, lightweight, and comfortable. Used in 40 degree UP Michigan nights and sleept deep!

All of the features you need!
The sleeping pad loops are awesome. The bag stays put when you move. There is room for different sleeping positions. The hood is comfortable and completely adjustable. Love this for Summer/Fall hiking in the Cascades.

Short summer backpacking comfort.
Very good mid-range sleeping bag. Probably the roomiest mummy bag you can find. Comfort rated down to 41 degrees. Has a full collar but the bottom has no fill and imo it’s not necessary. Has a draft tube and a stiffener, zipper doesn’t snag. The ‘toe-asis’ in the foot box is very comfortable. I find the link straps to hold well on a 20” wide 2” thick pad. Good for short summer backpacking trips. The 650 duck fill is fine for this application. I’d save a few bucks and go with the synthetic fill if car camping. There are ultralight and warmer 850+ goose fill bags out there but this is not an expedition bag and you probably wouldn’t be reading reviews if you needed one.

Great quality as long as it’s not cooler than 50° to 60°.
Very comfortable bag and great zipper. The only reason it doesn’t get five stars as because if it gets cold, you’re gonna wish you had a warmer bag. Even purchased the outside liner that goes with it that says it adds 15° to the warmth which is not anywhere close to accurate. Very compact and light white, but would not use it below 60° camping.

Item was used and not in original packaging.
As the title states I received this item used and not in the original packaging. It wasn't even folded up, just wadded up and thrown in a bag.

A top of the line sleeping bag meets my personal needs .
Rolls up compact And carries lite as advertised . Tested mine on a 3 day weekend colorado campout on national forest land this last may of 2024. Impressions this 32 degree bag kept me comfortable in temperatures tested down to 35 degrees and in rainy wet windy conditions using a pad with an r value of 4.2 ahh and and sleeping just with long underwear no socks inside the Crag Lake 2 man tent. I would advise to Add a liner to extended the comfort level when sleeping naked and also extend the life of the bag. Like the way this bag can be attached to the Pad to prevent what i call “a Roll Out” .

I used it for three nights camping. It got to around 7 c at night, and with not even a baselayer, just a inflatable sleeping pad I was warm until early in the am, I was a bit chill so put on my toque and was comfy. Nice bag! I got the small by accident and I am 5'8" and it was too small. Returned for large.

Soweit so gut. Ausgiebige Prüfung bei einer Norwegentour.

Ich hab den Schlafsack gleich nach Kauf in der Wüste bei 5 Grad ohne Zelt benutzt und er hat mich schön warm gehalten. Durch den Tau war er morgens außen naß, innen aber komplett trocken und ist - im Vergleich zu den (älteren) Schlafsäcken meiner Mitwanderer - sehr schnell wieder getrocknet.

UPDATE: temp rating is accurate. Used it on multiple islands on a lake during the Canadian summer, so cool nights when temp would drop down to 10-12 C) and the sleeping bag was way too warm. So definitely will keep you balmy in the Fall when night temps hover above 0C. Not tested in the field yet, so for now this is just gonna be a review of the build quality. In one word: Excellent!! Heading to Algonquin Park in Ontario soon mid September or so...thus will update regarding whether or not the temperature rating is accurate, ie whether I froze to death during a rainy night! 😉
