As the title says, i have a Batura that i use for very cold/ winter Alpine / exped, ive had a Neutrino for a few years as my go to down but I find the crossover quite close and realy haven't used it that much. I got an Infinity at xmas with a view to it being slightly less warm and heavy than the Neutrino and more usable for year round use.
The plan was to sell the Neutrino but I'm struggling to part with it as its a great jacket. The Infinity is not as warm or durable but does pack smaller and is lighter which would promote me taking it for tent / camp duty as well as for summer Alpine.
I think being objective ( and im loosing that by the second) the infinity and Batura covers a bigger usage range.
