Hi all,
Doing the overland track next year in summer and was wondering on what temp rating my sleeping bag should be. ( I know pws says -10° but can I get away with -5°

Thanks, cameron

I'd say you will be fine. Sleeping temperatures are all relative to the individual.

around -5 will be fine
Have a dry set of thermals to wear to be if required

We just completed the OLT and it snowed on the third night. We had -5 and -7 sleeping bags and we warm enough. Most nights I slept with just a fleece and was nice and warm.

I totally missed the -10 when planning and ticked yes to the questionnaire you need to sign when picking up your pass.

Only ever use -5 for all of my walks down here in Tas ,I do use a Silk Liner which adds some extra warmth.

At New Pelion hut on a cold October night I woke up in a lather of sweat in a -9 degree bag.

Even on the EBC trek it was plenty warm enough.

I don't user that bag anymore, a -1 degree bag is warm enough. And most often I only use it as a quilt.

So it's really up to you. If you are a warm sleeper like me you don't need a warm bag.

Thanks all for your replies,

I live in north qld so I wouldn't know what kind of sleeper I am because I always wake up in a puddle of sweat

Unless the bag has a certified rating or you can find a proper review, suspect BS. Ignore 'extreme' ratings marked on bags.
I'd suggest, if you want to get the best buy, to post a link or description to the prospect on here, someone will help. A '-5C' advertised bag could be generally cold at +5c

If you have the money a down bag will be lighter. If you have conscience for the geese, some 'ethical' down products are available.
Or(?) a quilt may be more useful in your situation? viewtopic.php?f=27&t=21674&p=316272&hilit=UL+Quilt#p316272
And considering utilizing clothing in the mix as mentioned (so you don't over-buy with the bag).

I use a -1c sleeping bag for 3 seasons.. even +4c if there's a good forecast.. (or until it was nicked recently), but always with some puffy clothing on hand jic. The -1c bag cost $280(US) and weighs 700g's

The -5 Bag I use is from this Manufacturer they have their warmth rating tested by Leeds Uni,it is a Tundra Pure and Dry,not cheap though https://www.tundrasleepingbags.com/slee ... ry-minus-5
