Malachowski 'Ultralight II 300 Sleeping Bag'
Wow check out this beautiful sleeping bag!

The specs on this thing are insane - no other way to put it.

It has 300g (10.58oz) of 850fp polish goose down

Total weight 480g (16.9 oz)... and that includes the weight of the stuff sack!

So that makes the weight of the fabric probably around 150 grams (5 oz) - wowzer!

The fabric is the super awesome Toray Airtastic.
