Lighter Blizzard bag

I've also noticed that, and at this weight and size (more importantly), it becomes very interesting. However, I was not able to find the most important information – how warm is it compared to the original one (for which some test reports can be found). It is made of "2 layer Reflexcell" – if the original is 3 layer (as the picture on blizzard website suggests), there are probably cold spots at the seams that are not present in the 3-layer version. Does anybody have some experience with it, or more information on how the new material looks like?

I had exactly the same question and although I don't have any experience, I did e-mail the company.

'Apart from the weight, is there any difference between the blizzard bag and the blizzard bag active range?
It says the active range consists of two layers – does that mostly effect temperature rating or durability?
I am mostly interested in the temperature rating, so if the original blizzard bag is warmer that would effect my decision.'

This was their reply:

'Thank you for your enquiry, there is a difference in warmth between the 2 layer and 3 layer material. The 2 layer has a tog rating of 6 the 3 layer a tog rating of 8, therefore, it is warmer and so it your situation I would advise the 3 layer.'

Hope that helps.

Thanks for checking Ito.

I stumbled onto this thread while reviewing my 3 season day hike kit. I still carry the AMK bivy, because of the weight and size-I don't want to carry a huge heavy item that I plan to never need. However, I have seen real world test reviews that show how it really is prone to getting the user cold and damp. Not good in survival situations. Is the Blizzard bag any better at preventing condensation, and would the lighter bag be sufficient for PNW conditions above treeline in summer? I can't wrap my head around 6 tog vs 8 tog of the original.
