Living in FL, I look for every advantage to handle the extreme summer heat. I've been wearing UA heatgear compression shorts for several years. This past Xmas was a chance to splurge on the much-hyped Skins brand A400s. I must say they lived up to the promos in relation to muscle support and "oxygen flow". I closeted my UAs and wear the Skins exclusively. My ?: will they be as cool as the UAs as the temperature now rises? Are they cool enough I should consider adding length with the half-tight? Will a compression shirt work in the heat? Appreciate any feedback!
