You know that the only shirt I wear out when photographing regardless of weather is my Simms Solarflex UPF 50+ Long Sleeve Shirt. These are great in warm weather (love my hoodie to keep the sun off my face) and cold. I put these on over my thermal underwear as they are smooth and my vest or jacket won't get hung up on the thermal. Thumb loops keep these shirts from sliding up your sleeve. I have many different colors and love them all.
