Right me again, and YES still on the hunt for a down bag. Recently bought a RAB Summit 300 1/2 zip, great bag, just far too small for me (width) couldnt put my arms by myside.
After many hours of google research it has come down to Cumulus Mysterious traveller (CMT) 500 , Cumulus prime 400 (CP) or golite Ultralite 3 season quilt long (GU3)
weight price comfort
CMT 1005g 175.00 -7
CP 905g 235.00 -7
GU3 776g 189.00 -7
both Cumulus bags have the exact dimensions one uses 400g of higher down, and the other 500g, so I guess it would be CMT as its £60.00 difference for 100g in weight, not sure its worth it. However I like the idea of the Golite as I could also use in my hammock, and it would definitely fit, but not sure how it would cope with temperatures below 0, if anyone is selling either/any of these and could comment on the performance of the golite as reviews are few and far between on the net. (I dont trust americans )
If it's for a hammock, go for the quilt. The down in a mummy bag will get compressed under you, and up the sides will get squashed too. It will then lose most of its insulating value. Buy a seperate quilt underbag made for a hammock if you intend to 'swing' in winter.
Temp ratings are relative. I've used 0C rated bags and a quilt well into the negatives with suitable clothing.
Also, i haven't checked those particular bags, but Cumulus bags usually have a differential fill. More down on the top than the bottom. Not a problem if you sleep on your back all night.
Excellent thanks guys, thats exactly what I need to hear. In regards to a mat at ultralight gear I can get the golite quilt for 199.99 and they throw in a POE ether thermo mat for free, I have no idea if this is a good bit of kit, seems like a deal to me, and I love a bargain .
Decision made. If anyone is selling get in touch, its payday next friday.
I bought the Golite 3 season quilt + POE mat deal. The POE mat is super comfortable but I don't think it works that well with a quilt. The problem is that it has sections where there is no real insulation, just a single skin of plastic, in between the long tubes. If you were using a sleeping bag then the down would expand into the spaces between the tubes and provide some insulation, but with a quilt the mat seemed chilly to me at around freezing.
I haven't had the quilt out in any really cold conditions yet so I can't say much about how it would cope I'm afraid.
