Comfortable, adjustable, efficient, with multiple carrying positions and the tether strap fits easily into the binocular carrying case. It could be a DIY project, but I suspect there isn't much savings below the $20 price point. For my new Bushnell H2O 8x42 binoculars, I modified the wiring harness by cutting the plastic plug that ties the two ends of the cable together, sliding the cable out of the clip that holds the cables together on the back, and threading the cable through the Having guided the eyepiece cap holder, pass the cable back through the retaining clip and tie a knot at the two ends of the cable. This keeps the eyepiece cap in place so you don't lose it. Then, to keep the Bushnell lens caps from falling off when carrying the binoculars because they are quite loose, I applied some Gorilla Super Glue Gel to the o-rings that hold the lens caps to the binoculars.
