I finally had a cool day to try out my new hoodie on an evening ride (65°F). It blocks the wind extremely well, and I'm sure it will be good down to the 40s, maybe lower. I'm 6'3" and 245lbs., the XXL fits perfectly with just a bit of room underneath for layering, if needed. Also, picked up one of Torque's cool-looking caps. Love this company's products! Keep it coming!
