The Thermoreg Long Sleeve Top Sr White is guaranteed to keep you warm. Canterbury’s iconic base layers have been updated. The new Thermoreg technology keeps you warm and dry. The tops are now longer at the back to keep the lower back well covered during exercise. The fit has been improved so that the shirt fits better with your body. The seams have been made even flatter and moved on the shoulder for minimal irritation. An extra piece of fabric has been placed in the armpit so that the shirt stays in place when the arms are raised. The new Thermoreg technology also ensures that no heat builds up. This way the body can properly regulate its own temperature. The fabric has an anti-bacterial finish to prevent unpleasant smells.
