    Hi all,

    Ive been using quilts, and Im now looking at Cumulus to get a new quilt. I saw the quilt 450 has a temp. rating of -1 at 710 grams. But the x-lite 400 has the same temp. rating, at only 575 grams! The diffrence seems to be in 850 cuin(quilt) and 900 cuin(x-lite), and in 29/m2 fabric(quilt) and 19 g/m2 fabric(x-lite).

    My main reason for going with quilts was the weight reduction, but now the sleeping bag seems ligher at the same temp rating! Is there still any reason to go with the quilt 450 and not the x-lite 400?

    Well, the obvious reason would be if you prefer quilts to sleeping bags; that's my reason for going with a quilt, not really the weight savings.
    Another reason would be the assumed greater durability of the quilt's material.
    I would also consider which has the smaller packed size

    I've not been over the specs as I have no interest in sleeping bags, but the xlite looks narrower, especially at the foot end. I'd be inclined to ask if they can customize to use the lighter fabric and higher fp down in the quilt.

    Thanks! What would you say is the advantage of the quilt over a bag for you, if the bag is lighter? In what sense would a quilt be pefered by someone? The bag has a pack size of 5.5L, the quilt 6L.

    Yeah thats what I asked them. I dont yet quite understand the down cuin system though. What would be better, having 450gram of 850 cuin down, or 400gram of 900 cuin down? If I want 900FP, they will reduce the amound of down with 50grams, I dont know if thats smart? Also, somewhere I read that you need to wash 900FP much more then 850FP down to keep loft. Any knowledge/ideas on this? Thanks guys

    Theoretically 450g of 850FP will provide more lofted volumen (and hense insulation) than 400g of 900FP. To get equivalent insulation you'd need 425g of 900FP to provide equivalent lofted volume. This is all theoretically.

    If you suffer from chlostraphobia quilts are good, the reason I got my wife one.

    Thanks, this is very usefull. It would not make sense to pay extra to have 400g of 900FP instead of 450g of 850FP then. Maybe 900FP and the price increase would be worth it at 450g of 900FP, then its warmer then 450g of 850FP for the same weight. Very usefull, thanks again

    Briefly, I find them less restrictive. Some people will prefer sleeping bags and others will prefer quilts.

    I use a regular width, long quilt (125cm) despite having broad shoulders, needing a wide mat (I literally hang off the sides of a regular width xlite) and I never have issues with draughts, even on my side. For me it's more that there's less fiddle with a quilt and plenty room to move around. They're simple, no zipper to break and easy to vent. Just flick your legs into the foot box, if it's cold snap the quilt and throw it over your head. I sleep with my insulated jacket on 90% of the time and if it's warmer than 3-4C I usually end up with the quilt around my waist. Not so easy to do with a bag.

    @Dave V did a really excellent review of the XLITE 300. Well worth reading. On phone so can't search. In 'equipment' maybe. Worth noting as a recent purchaser of the Quilt 150(190 with Ofill) my straps were not included in the weight listed on the site.

    If it helps any, I recently got a custom quilt 450 with 900fp down. They estimated a comfort rating of -4c and a limit of -10c. I also chose a pertex pro outer and an inside pocket. Haven't weighed it myself yet, but cumulus quoted a final weight of 730g on the tag.

    Hey! Thanks, I´ve been thinking of getting the quilt with 450gram of 900FP down and the 19 g/m2 fabric of the x-lite. Did you do any research in the bad effects of 900FP in comparison to 850FP? Some say it loses its loft more fast then 850FP.

    I asked this for my Cumulus Taiga 360. 850 -> 900 fp was 45 Euro. To change to Toray fabric was 40 Euro for the inner and 40 Euro for the outer shell. In the end I went only for the 900 fp. I thought the fabric change was a bit expensive, and while 850 -> 900 has very little downside (hmm), a thinner fabric will be more fraglie. Not that I am too worried for the fabric for a quilt but anyway.

    Thanks! Do you think it will be too hot for 3-season use?

    i had the xlite 300 on test which i used last year in the alps, temps dropped to-1, its a great bag and the material feels more robust than it looks. in the pic its next to my panyam 450, size wise the panyam is a little roomier.
    after dave v reviewed it i sent it back and got the taiga 360 which i again used in the alps this year. great quilt which is more than suitable for ground sleeping. Dave's going to be doing a proper review on that very soon.
