You can outrun the heat in the Brooks Atmosphere Short Sleeve 3.0. It has sun protection, stretch fabric designed to dry fast and it's stink-proof (really!).
Details:
Sweat-wicking: Breathable and lightweight GO₂ fabric wicks sweat and takes less than 7 minutes to feel dry on the body for long-lasting comfort.
Sun protection: UPF 40+ fabric helps protect skin from the sun.
Odor resistant: Feel fresh between washes thanks to the top's antimicrobial finish, which minimizes stink-causing bacteria.
