Effective protection from annoying and disease carrying mosquitoes and other bugs such as flies. The mesh is optimised for ventilation and outward visibility with a drawcord neck with generous length for tucking into collars.
Sea to Summit says:
Eliminate the irritation of mosquitos with this ultra light weight mosquito head net. 60% lighter than our standard head nets and twice as compact, the Nano Mosquito
About the Holes: STS mesh products use ultra-fine mesh that has 80 holes per square cm (around 516 holes per square inch). The WHO recommends a minimum of 156 holes per square inch for mosquito nets and there are many products with 2-300 holes per square inch.
Very lightweight piece of kit that can make a huge difference to comfort and safety - best use is when combined with a wide brimmed hat as per the photo. This Nano version is incredibly light compared with the standard net it will give the same protection but I guess must be less durable.
