Adding a performance first layer to your Seasonless ensemble makes a huge difference to comfort. The Max Long Sleeved Top is designed to keep the rider cool in the summer and warm in the winter. This is due to the clever use of a soft Melange fabric with technical finishes, Hydrocool® and Silverplus® which give the top enhanced wicking and drying properties, while also providing antibacterial protection. The result is a next to skin level of comfort that is second to none. This soft Melange fabric allows an armoured shirt or jacket to simply slide on and off and it stops any sticky unpleasantness in the heat, thus allowing the wearer to get on with the pleasant business of riding a motorcycle without distraction. Even the seams are flat locked for comfort which is complemented by the Max’s relaxed sports cut. Like the rest of the active base layers in the range this is machine washable and dries quickly. The men’s cut is available in six sizes, from S – 3XL Details & Fit Fast wicking and drying Highly Breathable Odour resistant and with anti-bacterial properties Flat locked seam construction for comfort Relaxed Sports cut Easy care and washing 6 Sizes S-3XL See size chart for details Knox Men's Upperbody Size Chart Chest: Measure around the fullest part of your chest and your shoulder blades. Waist: To work out your size, measure your waist in the position your trousers usually sit. As a guide this is roughly 2inches (approx 5-6cm) below your belly button. Please note: The measurements given are body measures and we recommend you do not measure over the clothing. Also please hold the tape measure firmly and not loosely as the measurement needs to be fitted. If you measure in between sizes or at the top end of the size, we recommend you go up one size.
