The Nike Long-Sleeve Element Sphere 1/2-Zip Shirt is my new favorite running shirt, its warm with nice thumbholes that have mittens to keep your digits warm without having to wear real gloves. So much easier to roll the mittens back into sleeves than to peal off gloves and then stuff them into your pockets. This shirt is soft and fits to move with you while you run. Of course it’s Dri-Fit so you won’t be weighted down when you sweat. I found this to be a great choice for 20-50 degree morning runs. I loved it so much I got 2 colors.
