I almost never use the lens covers that came with the binoculars. They have always seemed like total junk to me. Instead I use this Bino-Manager and it works really great. In addition to protecting to binocular from dust, water, etc. it also is a binocular harness far superior to the Crooked Horn Outfitters model.

This has got to be one of the most unique methods of caring your binoculars we've seen this year. The pouch, or elasticized cover, is made from camouflage water -resistant micro fleece material that will protect your binoculars from dust and water, but will still give you quick access to your binoculars. The Bino Manager comes with both the pouch and an elastic strap to keep your binoculars from swinging away from your body while your hunting, hiking, riding ATV's or any other outdoor activity. Available in Mossy Oak Break-Up
[It also is available in black]
The shoulder straps are made from wide camouflage neoprene material. A comfortable back support which connects the chest strap and Bino-Pouch to the shoulder straps and keeps the pouch in place when your binoculars are in use insuring equal weight distribution while eliminating sagging and sliding while optimizing comfort.
To use your binoculars, simply pull them from the pouch. The pouch stays in place giving you the freedom to use your binocular with out neck strain or having to force them away from your body like some other binocular caring systems
[for example, the crooked horn outfitters model.] When your through with your binoculars simply slip them under the pouch and there protected and held snug to your body. The Bino Manager will work well with any binocular or rangefinder with maximum dimensions of 8"H x 9"W x 3"D
