What mid-layer are you guys wearing on the hills when it’s REALLY cold?
Baselayer, legs and top.
Two thin fleeces from the pile.
Waterproof trousers and jacket.
Buff around neck, wooly hat, under gloves and big over gloves.
Goggles.
Puffy jacket and foam seat mat for if we stop.
Walking uphill I’m usually just in baselayer under waterproof, a cold day add a thin fleece.
Walking flat or downhill I add second fleece.
I’m good down to mucho below zero windchill.
Emergencies – we’ve old KISU and mylar sleeping bag, and I often have small gas stove. Experience says I’m good with that paired up with someone for 4 hours, even in -10 air plus windchill on the top of Ben Lawers….
