Never having to deal with Deep cold before I a intimidated a little by thoughts of -40C.
I do think I have can a sleeping system that will cope with that now tho; even if it is perhaps heavier than minimum it would be very flexible.
So my next worry is a modern LW system for cold camping and the niggle about being ultra safe Vs being loaded down with too much stuff that even tho each item may be LE the ttal is too much
Basics yes.
Hot-tenting the fellers over at Winter Camping will looked after me and I have a heavy traditional system all sorted and ready to use
I want to do some solo travelling.skiing using skis and boots I am comfortable and reasonably skilled with
I’ve decided on using Polartec ThermalPro with a LW wind shell as my main pants layer with Patagonia MARS pants as extra insulation
A Polartec ThermalPro hooded top with windshell as my main torso layer, a Patagonia Nano-bivvy as supplemental active insulation and I am ordering a Nanatuk Skaha pullover [ with 50% overfill] as my passive layer.
I have some surplus nylon windpants that I would probably add for extra leg protection but do I need to bring the M-65 liners as well?
Or given the possibilty of a chinook and rain are waterproof pants enough?
A similar question for my torso, will I plan to bring or buy an overparka and if so how warm should it be
