really quality product - nice features
described as three season but you'll probably need thermals for temps around 9/10c as I did

I'm 181cm tall, would you recommend the 185 or 200cm version?

Hi Johann,
For a user of your height I would suggest the 185cm option. I would only opt for the 200cm option if you want a little extra space in the bag and do not mind the extra pack size and weight.
Question from Angus

Does the bag have two zips? Can it open at the bottom to air my feet?
