The Thermoreg Long Sleeve Top Sr Red is guaranteed to keep you warm. Canterbury’s iconic baselayers have been revamped. 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 to your body. The seams are made even flatter and moved on the shoulder for minimal irritation. In the armpit is an extra piece of fabric placed so that the shirt stays in place when the arms go up. The new Thermoreg technology also ensures that no heat build-up occurs. This allows the body to properly regulate its own temperature. The substance is finished anti-bacterial to prevent nasty smells.
