The Smart Gloves have a mesh material across the back of the hand which enables air to circulate freely, preventing build up of moisture which leads to the hands getting cold and clammy instead of retaining warmth. The material also reacts to horses sweat and instead of becoming slippy on the reins the fabric increases its grip. Machine washable at 40 degrees they do not lose their shape and come up like new. The breathable nature of the fabric also ensures that bacteria does not build up that causes odours, so washing can be kept to a minimum.
