Keep those irritating mosquitoes or no-see-ums away from your face neck and head. It's made of ultra fine mesh to keep almost every insect out. Wear it over your hat or by itself. Elasticized neck keeps it tight to evade the relentless attack. One size fits all.
The head net when worn over a hat with a brim as shown on the picture makes the net not long enough to tuck into my clothes, there fore the no see um's got in and bit me. If you wear a ball cap, the net works better because it is "longer" and can be tucked into your shirt so there is no entry point for the no see um's. Probably should change the picture.
