Combi is an accessory that turns your water bottle into a light. Campers and hikers all know the struggle of having to carry too many items while being in the great outdoors. To help eliminate the burden, Combi is an accessory that combines two products into one. With the Combi water bottle cover, your bottle is both a water and a light source.
My initial design started off as a new high tech hiking bottle that had a built in light function. I eventually went in a different direction, and decided to design an accessory that you could add on to your bottle instead. I realized that this would be a more marketable product.
