    I ordered a Cumulus Quilt 350 nearly two weeks ago from Back Country and it arrived today.

    Probably not surprisingly the postage was delayed with the weather we had last week but I was a little miffed to find the outer package torn and the actual plastic the quilt was in was also torn. Thankfully no damage to the quilt other than it being a little damp. The shop owner, Andy was pretty good comms wise and I will be keeping an eye on his site for more goodies.

    After 30 minutes airing it really started to loft up and I am very impressed so far. All the damp clumps broke up and the spread nicely.

    The advertised weight was 585, mine comes in at 578 now I have taken one of the shock cord attachments off. I will probably save a few more grams when I replace the shock cord and cord locks. The stuff sack come in at a whopping 11g :p I won't be using this though as a dry bag will replace it.

    Build quality seems to be spot on, no sign of any down escaping, stitching looks very good and all the loop attachments and neck clip seem well secured. The quilt came with the stuff sack, three shock cord attachments in place with cord locks, 4 metres of 3mm shock cord spare, three spare cord locks and a net storage bag.

    I am 6ft and the top of the quilt covers my shoulders nicely with a little to spare, around 3 inches or so. It should work well with my Aegismax hood. When attached to my pad (Exped, Winterlite) with me on the mat and the quilt around me, there is plenty of movement space and the loft os not squashed, the footbox indoors is seriously warm.

    I should get chance to give it a go this weekend :)

    It's a great quilt, I've been using mine for several years and I'm super happy with it.

    Yep. A very nice quilt. It would be perfect if it was just a little wider right above the footbox.

    Great kit :thumbsup:
    350g of 860 (950ish) us puts it in the same bracket as top US 20 degree quilts and the weight is spot on too.

    How wide is it at the shoulders? I'm wondering whether it's usable without having the straps/shock cord under the mat, or have they trimmed the width down on the assumption that the user will always have it tied down to the pad?

    I've never used straps/shockcord under my mat for a quilt. Seems to defeat the idea of a quilt not being confining. As for putting your quilt edges under the mat as I've heard some describe -:stop:.

    Cumulus gives the width as 77 cm but that is with the top closed. I find there is plenty enough width at the top.

    I've only used it without the shock cords and it works fine once you've settled in. It just gets drafty around the hips if you turn around or try to lay on your side to read.

    I did knock up some straps similar to the ones supplied by Enlightened Equipment. They're not really confining and do help with bringing the quilt back in place if you move but I do prefer the ease of use of wider quilts. I'm seriously considering a modified Cumulus comforter for this reason.

    It'll be good to hear how you get on with it Dave, I've looked at the 350 quite a lot but never purchased. I don't really have a gap to fill with the quilts but Cumulus gear always gets good reviews.

    I've not used straps either.

    I suspected as much. No good for me since (a) i'm a side sleeper and (b) i move about a lot. i'll stick with my GramXpert and AsTucas quilts, which are both fine, and put up with the small extra weight.

    I've been over to see @Mole this evening to compare his Golite with the Cumulus. The enclosed area of the footbox is larger/longer on the Cumulus and the top of the quite is a far bit wider but other than that the sizes are pretty similar. I'm keen to get out and give it a go which should be this weekend after a gear/social meet for a local facebook group.

    Dave, I'll be interested to hear how to get on with the 350 as I very nearly bought one of those a few weeks ago. Instead at the last minute I opted for the M400 comforter (400g 850fp). Anyway eager to test tried a test camp just in the garden and well had to abandon and retreat to my warm bed at 5.30am. I was absolutely freezing and no this was not last week. air temp was about 3deg used foil blanket under an exped synmat ul7, Rab silk liner and merino leggings plus base layer and merino hiker socks which is my normal sleep system.:confused:

    Your experience with the comforter is interesting. I was really toasty in my 350 quilt at around 3° wearing thin Uniqlo long johns, socks, a very thin t-shirt and the lightest of Decathlon fleeces (so a bit more than you). I've heard of several people complaining about the down moving to the sides in the Comforter, leaving cold spots on top of you.
  14. Arne L.

    Absolutely. I've used the Comforter M350 for a while and it made me lose all faith in down.

    The down moved to the sides pretty fast and it was a pain to get in back on top of the quilt, resulting in a lot of cold (and frustrating) nights. I'm a pretty restless sleeper, though.

    I thought that my comforter might be underfilled.

    If I understand correctly, this is far less of an issue with their quilts?

    I couldn't imagine this being a -7C bag for me. Comparable with say a Panyam 450 or WM Ultralight (both 450g of high quality down), about -3 would be my limit in those, probably need layers to some extent as well.
  16. Balagan

    Balagan Thru Hiker

    Yes. Instead of having one continuous baffle across the width, the quilts have three: one across the top and a smaller one on each side so there is zero down movement.

    I think they have different amounts of down in the panels too. I have the 150 and it does. From what I hear the 20 degree rating on the US quilts is taking into account a puffy etc.
    My myog 560g quilt I'd use to just under 0. Perhaps -8 with my overbag, at which point I'd start putting mid layers on.
    If I'm run down and haven't eaten properly then add 5 degrees to that.
  18. Balagan

    That would go some way towards explaining the discrepancy between EE's temp ratings and fill values compared to those of Cumulus. I'm sure I could get the 350 to pretty low if I was wearing my 400 g down puffy. ;)

    Not sure about the puffy but EE do assume you are wearing one of their hoods and a "winter" sleeping pad.

    I’ve never really taken temp ratings as anything more than a guidance.

    One of my old Snukpak bags (yeh I know) was rated to -7, I was cold in that at 0. My alpkit pd400 is rated to -6 but I’ve had it to -8 and still been warm enough. I used my old alpkit quilt down to +2 without an issue.

    I sleep warm and tend to use fewer layers when I set camp, if I get a chill in the night I have layers to put on. The only place I always feel a chill and layer right away are hands and feet.

    It will be interesting to see how this quilt performs for me, I will report back :)

    Well I don’t know what the temp was last night but I was too hot under the quilt. Ended up laying with the quilt over my feet & legs and a merino top and light fleece kept me plenty warm :) I have a feeling that I’m going to need something much much lighter

    The 150 does me with a hypertherm from 9 degrees ish, say may to sept excepting colder periods, that's low level se england of course.

    Yup, I think I may have to rethink my plans. I was going to get a winter quilt made by them but tbh, I may have a custom 150/topper made instead and double them up when needed.

    I finally decided on a widened 350 quilt rather than a comforter and shot Cumulus an email to explain what I wanted and get a quote. Interestingly, they asked me to get in touch in a short while as they were in the process of introducing new versions of their quilts. I'm curious what they have planned.

    Me too, as I have yet to find a reasonable cost quilt for my not exactly massive 47" chest. I had a nice 160cm synth one made up in Apex 200 but it is fairly bulky. I reckon a 145-150cm one should do the trick. A 80cm (160cm) sleeping bag is pulled tight around me affecting the top loft when done up. I can't fasten a 75cm one and 70cm and below just forget it!
