My brother just designed a new product called Opti Skinz. They are the only one on the market of it's kind that encase your Binos and protect them fully. I have been using them for the last year and they are awesome. I have tried the others out there and they just don't do the same.
They are new on the market and Scheels stores in ND are selling them like hot cakes so take a look at them and see what you think. www.optiskinz.com
