I bought a harness several years ago, (can't remember the brand any more) probably paid 10 or 12 dollars for it. I had a loper hunt that I went on and was concerned with dust getting onto the lenses while driving the ATV on the dirt roads. I took a 2 inch piece of string and super glued it to the lens cover that comes with the bino's and the other end to the bino itself. Has worked great. Cost was 4 pieces of 2 inch string and 8 drops of super glue. weight difference is nothing, increase in size of the equipment being carried is nothing. The system has been fail proof for 12 years and counting. Personally, I would not pay for a cover to put the bino's in. Bulky and just another item to open and remove before using the bino's. I flip the cover off with my finger while raising them and they hang below the bino out of the way while using. If interested, I will post a picture, just let me know.
