Review on Duofold Weight Varitherm Thermal Medium by Danny Zapata

Probably the most convenient product I have ever bought. I took the shirt to compete with the set and wore it 3 days in a row for 20 to 40 years of building. My colleague kept complaining about how cold he was and all I could think was that I felt like I was sweating but I was dry. I know what it's like to sweat and freeze and shake all day, it's awful and painful. This allowed me to sweat and take off my jacket, then cool off after about 30 minutes and then come back. It has never been cold. They even took a little rain and pushed back the water, it seemed. The shirt and overalls kept my shoulders and arms dry. I will buy another pair when they are definitely worn out.
