A mesh coil is the most modern type of vape coil available, rather than the traditional Kanthal wire wound into a coil with cotton threaded through the middle, a mesh coil is a very fine mesh strip shaped into a tube shape. The cotton is formed around the mesh strip leading to a greater surface area of coil coming in contact with the vape juice at one time, which is thought to produce a much more flavourful and long-lasting vape than traditional coils.
