Awesome quilt!

  • Familiarity: I've put it through the wringer

I have used Nemo spoon bags for a while now. Love them. Very roomy, warm, and relatively light and compressible. I am mostly a back sleeper but I do sleep on either side frequently throughout the night. I'm a a hot sleeper too so the bags just ended up being too hot for me. I decided to pull the trigger on a quilt. The siren went on sale and I nabbed it. Retail is too high in my opinion, but nonetheless a great quilt. At first impression I thought there is no way this would be warm in 30 degree weather. It is so light and seems very delicate. To my surprise, it had me toasty in 36 degree nights. It compresses down to a 1L bottle or smaller. I got a 3L compression sack for it...fits no prob and packs wonderfully.
The back drawstrings take a little getting used to. In fact...a quilt in general takes some time to get used to. I've shaved over a pound off my base weight...and freed up a lot of room for food. I even upgraded my sleeping pad to a new air xlite large. My suggestion if you plan on using a quilt, is to select a pad that has insulation from seem to seem across the entire width of the pad. I originally had an xped synmat hyperlight...and it does not have insulation in the outer baffles reducing the efficiency of a quilt because it allowed heat to escape on the edges of your system. The xlite has been MUCH better...and more comfortable too.

There is NO WAY I would be able to sleep with the pad inside the quilt. I'm just too bulky. If you are a petite person 160- and thin, you might be able to pull it off. I don't think you would be able to in cold weather though. It's warmer to sleep with the quilt tucked under your body on top of the pad.

All in all I'm extremely happy with this quilt! It's great for 3 seasons. I go to Ouachita national Forest for my trips if it's any consolation. Imo this quilt is a top performer in 50-60s for highs and mid 30s-40s for low temps. Of course a lot depends on your shelter too. If you are using a 1 man with the rain fly on, it will trap a lot of your body heat effectively raising the interior outside temps could be below 30 and you'd still be ok. I use a copper spur ul3 with my wife as a 2 person tent...and it's so roomy and we'll ventilated that it doesn't trap a whole lot of body heat. Maybe something to consider if you are shopping for a bag/quilt.

I highly recommend this quilt though!
