I have posted on several threads about my "NEW" needs regarding staying warm. After a bit of open heart work 7 years ago I was told by everyone I would get cold... Did not happen! However, after a stent in August, a year ago things are very different.
I now need warm stuff.
I have been using the wool stuff I have had but did not use until it really got cold more often now. I start with a poly or UA base and then add merino wool over that. Then go to a 100% wool sweater (Filson) over that with a heavy fleece Jacket outer. I use loose fitting pants of camo or wool depending. This combination works for the body and my feet seem to be OK with insulated boots and wool sox. Actually, its very comfortable both in temp and freedom of movement and not too bulky at all.
Its my damn hands that kill me. My fingers turn to ice quickly if exposed once the temps get below about 25. I use a thinsulate glove on my left hand and stuff my right hand in a pocket with some chem packs to keep it warm.
There are times that the temps reach down to 20 or so and I just do not go sit... walk, maybe, depending on how I feel.
