SportsTrail Cooling Arm Sleeves for Men & Women – Breathable, UV Sun Protection, Sports Arm Sleeves for Women, Men & Youth

They make some that are breathable, such as this one from Amazon https://www.amazon.com/SportsTrail-Cooling-Sleeves-Women-Moisture-Wicking/dp/B0BWPK566N They make unisex versions that are bigger around as well and a lot of color options. I didn’t suggest compression sleeves because the ones I’m familiar with are almost like neoprene, way too thick and not breathable. I’ve worm them for hiking where sunscreen is annoying to keep applying.

One of the best purchases I ever made when I started commuting was an arm sleeve. https://www.amazon.com/SportsTrail-Cooling-Sleeves-Women-Moisture-Wicking/dp/B0BWPK566N
