General   (General discussion, talk about anything.)

If this guy is ex forces which I think I have read somewhere he will know his field craft, the most important thing in cold weather is to know how to layer your clobber, preparation is the key which I suspect he will have sorted. First layer of clothes is the 'wick' that draws your moisture away from the skin and keeps you dry, wool is best. Next is your insulation, wool again or feather down jackets etc, both trap the warm air inside, last thing is to keep you dry from the weather a waterproof jacket, Gortex is good. Keep clear of fingered gloves as they separate the fingers and allow more surface area to be exposed and get cold, wool mittens are best but not good for dexterity etc, if you need to scratch your arse and stuff. Good footwear are a life saver loosen the laces a bit for circulation, Gortex again with wool socks, oh never forget a hat your bonce is a big heat loser. Keep your fluids up too. If you are getting out and about reduce all of the above body layers because you will sweat and it will freeze and you'll get very cold again.

Remember shivering is your bodies defence mechanism listen to it and wrap up.
