Carhartt Base Layers will help keep your temperature up when the outside temperature goes down!
NEVER HOT, NEVER COLD, NEVER DONE.
Force Extremes™ with 37.5® Technology helps stabilise your body's temperature. For the average person, the body strives to maintain an ideal core body temperature of 37.5 deg.C. You are most comfortable when the micro climate next to your skin has a relative humidity close to 37.5%. When you are in this ideal comfort zone, you are also in your ideal performance zone. The 37.5® particles are naturally embedded in the fabric, and will never wash out for the entire lifetime of the garment.
How does it work?
END THE DAY AS STRONG AS YOU STARTED.
