Same features of our model 15TH with the three given lenses but this time in a version with its RX optical insert included in the case. The user simply has to bring the RX optical insert to his optician that will insert the correct presciption lenses. The sunglass can obviously also be used with normal contact lenses. On the top of the given RX optical insert, there is also an extra under rim included in the package thus to start customizing your sunglass from the very beginning. Several rims in various colors can be purchased apart. Rigid case, lens cleaning cloth, warranty and a further microfiber pouch complete the package. For short-sighted and astigmatic cyclists.
