suggestions for a lightweight racing sleeping bag?

[jamiep]

Must be about 6 degree comfort rating and weigh around 650g. Any suggestions? My shortlist:

Alpkit Pipedream 300 (struggling to accept the stitch-through construction, dunno why really)
£146, 650g, 300g of 90/10 goose down with 700 fill power, 5deg rated
https://www.alpkit.com/products/pipedre ... term=PD300

Snugpak Adventure Racing (this is in the lead so far for me due to the quicker drying synthetic filling)
£120, 650g with Paratex filling, 5deg rated

Vango Force Ten Catalyst 250
£150, 650g, goose down Fill 90/05 with 700 fill power, 7deg rated

Looking at the pics, it's hard to believe it can really be that warm? ... it's as flat as a sheet

I'd also consider a Western Mountaineering Highlite although it'll cost quite a bit more than the others.

Another one for the light, but not exactly cheap category http://www.zpacks.com/quilts/sleepingbag.shtml
Their 40 degree bag might make you rethink your 650g figure.

Have a look for rab top bags - they might not do them any more, but with a sleeping map and an insulated jacket I find mine toasty. 500g or so.

Stetch the budget for a PHD? Half your target weight...

Zippy has his PHD bag up on the classified

lighter and smaller pack size than the others listed, although more ££'s

Worth considering, the Minim Ultra may be the best £200-odd I ever spent on bike touring kit. Every trip out using it, my bars have 300g less weight on than with my ME Xero 250 (which is a good bag for 4-8 deg at 600-650g.) The Minim feels a bit cooler than the ME despite the same rating though.
Not sure if I'd bother with primaloft-type filling for a racing bag, you can't afford to let the bag get wet anyway so maybe better to keep moving until you find better shelter. Good tip though as I'd like a bag like that for pottering about.

Cumulus lite line 200? http://www.trekking-lite-store.com/Schl ... ::499.html

About £140 delivered from that website, 518g and has 4 degree comfort limit.

I've got the Snugpak on test, it hasn't had a proper bivi yet, but I used it in the van at about 5° and was fine, with a bivi bag it'll be warmer. So far I really rate the construction (and mines only a prototype) and it is truly tiny. I'll report back after the WRT on how it looked after me

Not good then? Is a bin bag better?

I haven't any personal experience so happy to bow down to the more knowledgeable but the OMM blurb doesn't instill confidence.

designed for experienced users who know how to balance the incredible weight and space saving attributes with the consequential limitations

and

not designed for general purpose use and is only recommended for experienced race/event competitors or as a safety/emergency bag to carry with you in the mountains and wilderness.

Sounds like more of a death prevention device rather than the recipe for a cosy night!

[scott of the woods]

Lol death prevention device

Ask kbrembo as I'm sure he said he had one. However, he's a highlander, so a sleeping bag is a mere technicality...
