Inside the Mithos Bag should fit anything you need to successfully race a track. It has 6 pockets, the biggest one should have enough space for your combi, then there are 3 smaller ones on one side, one lean one on the bottom and on top a waterproof one for your boots. Inside the biggest one theres another pocket for little things. Of course this Bag is gonna be heavy when filled, so we've concipated it that you can move it as a trolley if you like.
