Thread: -8 or -11 sleeping bag for winter hunting CNI

Hi all

I realise there's a heap of sleeping bag threads, but I still haven't really come across one that deals with my specific situation.

I hunt in central north island, and use a tent in winter (often in clearings, but always below the bushline in Kaimanawas and Pureoras). My sleeping mat has an R value of 3.2. No idea what the temperature rating of my current sleeping bag is, but I've had a few uncomfortable nights curled up in a ball trying to get warm.

I have decided on the One Planet Cocoon, but my question is: shall I get the -8 or -11 degree bag (limit ratings for men)? I run fairly warm, so my gut feeling is the -11 bag would be overkill? Keen to hear from any hunters who tent in winter in similar conditions and what temperature rating bag you're using.

Any input would be most appreciated, cheers!
