Hi Lapped1,Mountain Hardwear does a compression fit long underwear that keeps you warm too
Check out their Continuum Midweight
I've been wearing it under my track leathers and under my street gear.
Its a little more expensive than Under Armor but it works really well.
Ditto for me for cool/cold weather rides. I bought a very light weight merlino wool undershirt at REI which is very good for those transition days which start out cool and warm up after lunch.For touring I recently switched to merino wool hiking underwear. Natural fibre seems to work over a good temperature range and they don't smell nearly as bad as synthetic, especially good on a longish tour.
I read in Australia's TWO WHEELS mag that one of the journo's wears compression wear, like sports people do in training, under his leathers, and was given this tip by a leathers manufacturer.
We are heading into winter down here in OZ so I am wondering about thermal style underwear or these new compression garments or a combo of both if thats feasible.
Do compression garments retain heat like thermals or are thermals the better allround alternative? Or are compression garments the new thermals?
I also wonder, in the event of an accident, what would be the outcome with heat generated would do to the spandex or elastene thats so close to your skin?
Do you melt plastic into your skin, making recovery worse or am I talking shit?
