Gripgrab Ride Thermal Short Sleeve Base Layer The GripGrab Ride Thermal Short Sleeve Base Layer is a versatile base for any cycling outfit in cold and mild conditions. The two-layer construction uses poly-blend materials that are both highly breathable and moisture-wicking, to leave you dry and comfortable so that you can focus on your ride. To keep you fresh and odour-free, this base layer features PolygieneR treatment. Its 'Wear More. Wash LessR' technology uses silver ions to reduce the build-up of odour-inducing bacteria. The treatment is entirely safe to wear against the skin and doesn't wash out. Reduced bacteria build-up leads to reduced odour and therefore reduced washing frequency, meaning that PolygieneR can also significantly extend the life of a base layer and minimise its environmental impact. Features Insulating PolygieneR anti-odour fabric treatment (biocide: silver chloride) Lightly compressing fit Breathable Ideal for cold to mild conditions
