TIP: The online Bushwalk Inventory System can help bushwalkers with a variety of bushwalk planning tasks, including: Manage which items they take bushwalking so that they do not forget anything they might need, plan meals for their walks, and automatically compile food/fuel shopping lists (lists of consumables) required to make and cook the meals for each walk. It is particularly useful for planning for groups who share food or other items, but is also useful for individual walkers.

Sleeping bag temperature Tassie & Vic

Sun 09 Aug, 2015 11:10 pm

Hi
I am in the process of buying a new sleeping bag and despite lots of Googling and forum searches, I still cannot decide whether I should get a -7C or -11C rated bag.

It will mostly be used for multi-night walks in Tassie and the Victorian high country in autumn and spring. I do sleep in a tent not a hammock. I am leaning towards the -7C because of the weight advantage and I do sleep warm.

I am looking at the One Planet Bushlite series and Mountain Equipment Alpinlite (not that keen on a tight mummy).

Thoughts on suitable temperature rating?
thanks

Go the warmer of the two but as a quilt ;)

Make your decision on the Comfort rating NOT the Limit of Comfort.

I am not a warm sleeper and a comfort rating of -7 would work well for me in the conditions you describe.

-5C is enough to cope with 3 season Australia. -10C is only required if you are doing winter alpine, or intending to also use it outside Australia.

I agree though that it is worth understanding the EN13537 ratings and what they mean, and whether you need to use the top or middle of the scale http://sectionhiker.com/deciphering-en13537-sleeping-bag-temperature-ratings/

I went overboard after a below -10 degree night near Kosci early one March, and walked for many years after that with a heavy -15 deg bag. I was very happy in other -5 to -10 nights in Vic and NSW high country (non-winter) over the years. But most of the time I was too hot. My approach now is to layer for sleeping, just as I layer clothes. I wouldn't dream of taking one big super-warm jumper.

So, I now use a -12 deg quilt for the high country (mainly Tassie) - which is about a third of the weight, or less. I wear down jacket and pants to bed to make it warm enough in snow in winter. I also have a lighter summer quilt for the flatlands. I sleep COLD.

SO, I vote for the -7 for you, and add 'evening wear' as needed.

Quilt versus bag is another issue, but I'm glad I made the shift.

Another vote for a genuine -7 bag.

As others mentioned, just have a plan to boost the warmth a little (extra clothing, vapour barrier) for the occasional night you do need it.

Thanks to all…I have a S2S TrekII with 500gm of 650 down, the bag is rated (lower limit) at -7 and I have slept in sub-zero temperatures with it and a female friend used it at 0C and was warm, so the relative EN rating seems OK and I am happy enough to sleep in extra clothing if required. The OP Bush Lite -7C has a similar weight of 800 fill down and a water resistant shell. I am not brave enough to do extended time in the alps, let alone the AAWT with a quilt…but might try one as a summer bag.
I think I am going to order a OP Bush Lite -7C…with the poor aussie dollar (over $700 to import), PP wanting >$900 for the Western Mountaineering Alpinlite, dollar and Pinnacle offering 15% off One Planet bags and only a minor weight penalty, it seems a straight forward choice.

I have bought and tested out an exped comfort 800 extra long SB. It is very warm and is a winter down bag rated to neg.9. Up at Fed. hut last weekend ( Mid Aug. Vic Alps at 1700 M. in snow ) I was a bit too warm ! Mind you I was wearing thermals and a fleece jacket to bed with a balaclava on my loaf.

Nice bag that. Got one myself. Mostly use it open flat like a quilt or with the foot zip open unless I'm using it overseas in more brutal conditions

It's a pity the exchange rate is such crap at the moment, otherwise I'd suggest the Marmot Plasma 15.
This is a magnificent bag, the -9 rating is spot on and I reckon it would cover all eventualities in Aust/NZ.

I've been very cold and uncomfortable in a -2deg kathmandu bag... so when pinnacle outdoors had a sale on One Planet I lashed out on a lovely -10 bungle. Just need to go on a winter trip now that doesn't involve lodges! :)
