Baselayer (Layer 1) Long-sleeve wool or synthetic top. Quarter zip styles will allow for better temperature regulation. We recommend light colors, which best reflect the intense sun on hot days.
What Works This is the first layer of your system. A baselayer top with long sleeves will keep you protected from the sun and provide warmth when the temperatures drop. When things heat up, you can always roll your sleeves up for extra ventilation. This top should be a quick-drying, fast-wicking, light-colored, non-cotton, and comfortable.
