This should take care of the chill you might get on a hot day ride where you get caught in a sudden thunderstorm. Cotton, in contrast, holds the moisture up against the body. On top of the wicking undergarment, you layer with light layers rather than heavy ones. A good pair of padded biking shorts go a long way in helping to deal with the wear and tear of riding a bike saddle. You might consider wearing tights on those cold weather rides.
Many people choose to wear padded biking gloves to alleviate some of the pounding of riding.
On those cold weather days you definitely need wind resistant gloves. When considering what type of socks to wear, again consider weather conditions. On those warm summer days cotton socks might do fine, but on those cooler days, wool socks will help your feet to stay warm. A pair of hiking shoes or sneakers should do just fine for footwear. You need to be concerned both with hydration and intake of food so as to be able to sustain the energy level necessary.
