Cotton T-shirt? Oops.

I'm still using the recommended methods back when I was competitive
bicycling. Three layers. First layer next to the skin is a wicking
material, second layer is a fleece like layer and the third layer is a
wind/water shield layer that allows water-vapor passthrough.

Cotton t-shirts were never recommended unless it was very hot and the
sweat-soaked shirt would provide evaporative cooling through direct
exposure to moving air.

The idea behind the three-layer approach is simple. Move the moisture
away from the body as quickly as possible. (this wicking material will
also prevent moisture from moving back towards the skin). Form a
thermal barrier through which the moisture wicks outward and then
evaporates on the outside. If you need to stop wind and water
penetration, an outer shell which passes water vapor outward and
upward is necessary. The outer shell, which otherwise has no thermal
protection should be loose fitting and allow air movement underneath.
Don't secure a parka tightly at the waist, wrists or neck. Let it do
one thing and one thing only--block wind and rain.

I don't know the current think about socks, but I use the two layer
approach there too. A thin liner sock keeps moisture away from the
skin and then an outer sock (typically whool or some poly material)
provides insulation, padding, friction protection and moisture wicking
to the outside of the shoe.
