Do you want to be completely sure that your discs and your GRIPeq bag stay dry on the wet days? Then a Grip rain cover is just the thing for you. The rain cover from Grip is specially developed for Grip's own bags, and it therefore comes in two sizes:
Size "X" fits the CX1 bag
Size "XL" fits the BX3, AX5, AX6 and PX1 bags
The rain cover is made to fit the bags perfectly, and so you can open your bag and reach your discs without taking the cover off. The rain cover is supplied separately and does not come with a bag.
