Winter Mountain Clothing - Layering system and packing for Winter

Expecting the arrival of the 2019 Welsh Winter I thought I'd share my system for clothing layering and how I pack my rucksack for Winter mountain days in Snowdonia. I hope you find this useful and hope it helps you in choosing some of your own gear for this Winter season. I'd be interested to hear some of your tips on Winter gear so feel free to comment below.
