Note the Baltoro 1000 isn't listed but i have had the product code confirmed by PHD
Typical operating temperature -31°C this will keep you warm anywhere.
It also has a drishell outer to help keep the down dry.
I can obviously provide pictures on request. This a brand new bag that has never been used. You can also come and have a look if you want to, I realise its quite expensive but staying warm isn't something to be taken lightly.
