A much neglected topic. Less sex appeal?
Rain gear might deserve it's own thread. How, oh how, to keep the rain off and not get "WET FROM WITHIN," especially when working some?
Recognizing the problem, some new stuff is out there to improve on "regular" Gore-Tex: Gore-Tex XCR; Lowe Triplepoint Ceramic; Entrant GII XT Laminate; EVENT Laminate. Some stuff is far less breathable: Conduit; Sympatex; North Face Hydroseal.
And an old idea, the water-repellant "windbreaker" for all but real downpores, has returned with better materials and a more trendy name: the "soft shell." Nextec and Schoeller Dryskin Extreme are
VERY water repellant and so breathable that Gore-Tex is not in the race (Nextec is twice as breathable and Schoeller Dryskin Extreme is six times as breathable as the best Gore product. Nextec does not require reappliaction of "durable water-repellant" on outer surface, so the military likes it. Schoeller Dryskin Extreme now appearing in Marmot ATV on clearance at a well-known off-price/catelog/Internet seller. Google: Marmot ATV "Schoeller Dryskin" sierra for possibilities.)
Polyester fleece. :thumbup: :thumbup: :thumbup: I like polyester fleece for mid-layer insulation. I have not noted any problem with stink. I think that was a polyproplene issue (Phew!

).
Wool is surely good, even as compared to polyester fleece. Wool is: far more spark/fire resistant; less abrasion resistant; less warm when REALLY wet; actually generates significant heat (exothermic) as it gets damp - up to a point; heavier when wet; harder to dry; very wind resistant in some forms. Wool is still my choice for socks. (I've tried fleece sock, but they feel off to me somehow. Maybe too warm? Clammy 'casue it doesn't absorb moisture like wool does?) I have some "boiled wool" German and Swede surplus trousers that are real favorites.
It is axiomatic that cotton should be avoided in cold weather - and cool/rainy weather - even in Texas.

It holds mosture on its inner surface and cools -as it does in hot weather. Especially bad for next-to-skin layers.
And I wonder why Under Armor pushes moisture transport in a hot weather inner layer. More "comfortable" to be dry, but don't you lose the cooling effect of evaporation if the moisture is wisked to the outside of the garment, away from your skin??????
Trapped air between multiple thin layers may offer more insulation than the material making up the layers.
