It was 51° today when I got off work. I wear thin t-shirts and cargo short for work, I bike directly after work thus was wearing a thin t-shirt and cargo shorts. I was most comfortable, LOL. Loving the low 50° temps for riding. My gloves aren't dripping wet from wiping my brow before it runs into my eyes and stings my contacts making me stop.
Yesterday it was 54° when I rode. Figured I'd wear a pair of sweatpants along with just my t-shirt. Big mistake. It may as well been back to the high 80's and extreme humidity. I was drenched with sweat.
