The Sun Mountain Kube is a wheeled golf travel cover. The cover comes in the box as a compact hard shell which can then be extended into a full size, durable travel cover. The cover has 2 straps on the inside and 2 on the outside to keep the bag securely locked in. Inside the case there are pockets that you can use to store clothes, equipment or whatever you want to keep with your clubs. The top of the bag has extra padding which will help to give your clubs extra protection. To make sure you can find your clubs at the airport and to minimise the chance of them getting lost, there is a window for your name and address. The easy glide wheels and rubber handle make taking the bag around airports and other places incredibly easy.
