Reproduction of the standard issue helmet net used by American forces in WWII. Although there were several variations of nets, this is by far the most common one seen in period photos. They have 1/2" holes and are olive drab in color. Khaki nets did exist, but they are rather uncommon. It's relatively simple to discern that most nets are a darker color than the helmet in period photos.

How to attach your helmet net to your helmet.
1. Grasp each side of the net, one side in each hand, and pull to stretch. A Herculean effort is not necessary. Don't try to tear it in half like your 'ripping the phonebook in half' party trick.
2. Lay net flat and place helmet, top down, onto the net.
3. Bring up one corner to bale and slide chinstrap through one of the holes in the bottom of the net. Any of the many holes will work, there is not one specific one. Repeat for the other side.
4. Begin drawing string and tightening up the tension on the net. At this point, you can start to slide the net around the edge of the helmet. Just keep working the tension until the net is completely around the helmet.
5. Loosely tie off the string. Don't tie a permanent knot, just enough to hold the net on until you put in the helmet liner.
6. Insert helmet liner.
