Now here is another question as a follow up to the recommendations for mesh base layers. I see in the picture posted a short sleeve mesh base layer. A lot of my sweat shows up on my arms and legs. If the base layer acted to help more efficiently evaporate the sweat off your skin by wicking it out to a high surface area on the outside of the layer AND not heat you up by insulation, why not wear a long sleeve one under a short sleeve jersey? Wouldn't that be even better than the short sleeve base layer? Similarly wouldn't folks wear a full leg length mesh base layer on the bottom too? Wouldn't more of it be better? The improvement in cooling could be substantial...if it is real.
