Review on 🚴 ROCK BROS Thermal Arm Warmer: Unisex Arm Sleeves for Enhanced Cycling & Running Performance by Tutan Beatz

I got these thermal sleeves specially for the 2019 Bank of America Chicago Marathon. The weather was below 40 degrees and these sleeves came in really handy when warming up during the race. I didn't want to rub the rubber band against my bicep, so I smeared it with petroleum jelly. I measured my biceps and found the right size using the size chart, but felt the elastic was still too tight. Maybe because this is my first pair and I'm not used to wearing something on my arm I felt they were tight. I completely forgot about them once I got used to them. Finally, they kept me warm throughout the race and I didn't get as hot as I thought. I highly recommend this product.
