I’m determined to make a copy of this Montbell pop-up bug net, but I don’t have a clue as to what the flexible wire material is that gives the tension and makes the net self supporting. Obviously the wire has a memory which allows it to pop back into the desired shaped when deployed. The MB net is basically a smaller, light version of the A-16 Bug Bivy. The moving pic at the bottom of the link might give a clue to the question, I don’t know. Thanks.
