So I need to get leggings and a long sleeve top for my son for soccer. I plan on getting the cold weather for sure but was wondering if I should get the warm weather also? My question is will the cold weather be to hot to wear at a certain temperature point? Would the warm weather even provide any additional warmth if it is still to cold for shorts and tshirt?
Edit: My son is 5 so my only performance concerns are keeping him warm 
Any other brand suggestions?
