60% lighter than our standard head nets and twice as compact, the Nano Mosquito Headnet is comfortable and easy to use. 15D UltraVis light mesh offers great visibility and air flow Fine, 80 hole/cm² hexagonal mesh Soft multifilament fibre Superlight elasticised neck draw cord with cord lock Weight - 11g Ultra-Vis is a 15 denier, 80 hole/cm2 hexagonal Nylon mesh. Being a lighter, more compact mesh than Ultra-Mesh, we use it for our Nano mosquito nets and headnets. It is the mesh we use when packed weight and space are at a premium. We use black Ultra-Vis in our Nano Mosquito Headnets for optimal vision, and grey Ultra-Vis in our Nano Mosquito Nets to strike a balance point between visibility through the mesh, and ensuring the mesh can be seen easily.
