They go by many different names: Binocular harnesses, Binocular neck straps, Field binocular neck strap, etc. They are basically the same thing. A shoulder strap that holds your binoculars or telescope to your shoulders so you have both hands free for other things like a rifle.  Here is the best binocular harness for the money.

Size

This is one of the most important things to consider when buying a best binocular harness for hunting. You could have an amazing binocular harness, but if it doesn't fit the size of your binoculars then what good is it?

Material

There are many different types of materials that can be used in binocular harnesses, from leather to nylon to cotton. Nylon is tough and durable while also remaining lightweight, but it can also be rough on your skin after prolonged use. Cotton is the softest material, however it cannot really take much abuse before wearing out. Leather is in between these two materials; it feels nice against your skin while feeling like the other materials in how well it stands up to abuse.

Center of gravity

One of the biggest issues with binoculars hanging from your shoulders is that they provide a large surface area for wind and other forces to try and knock them off balance. The best way to counter this issue is by securing your binoculars at their center of gravity, which is directly underneath where the cups meet at the front.

Ease of access

The whole point of binocular harness is that you have your hands free to use a rifle or hold an object, so you want it convenient and easy to get at. If it’s too far away from your body it will be a pain to reach back for. Too close and it will just dangle around getting in the way.

Comfort

By this point you can probably guess that it doesn't really matter how nice and soft your binocular harness is if it hurts to wear. Unfortunately, comfort is completely subjective; what one person finds comfortable another will find uncomfortable. The best thing you can do is go to a store and try on a few different types of binocular harnesses and see which one is the most comfortable for you.

With all my experience with binocular harnesses, this may be the one thing that you really need to get fitted for. If you go into a store and try on what they have, chances are it could end up not being the most comfortable option for you.

Price

Some binocular harness can cost hundreds of dollars, but you will be surprised how affordable the best ones are. I have gone on hunts where I need to carry extra stuff like my rangefinder or binoculars for one reason or another, and all I had was a strap around my neck.

This really shouldn't be too much of a problem with all the products out there today; however, sometimes products can be extremely overpriced because in the mind of the company, this is an essential item. While I do agree that it is important to have a good quality harness for binoculars, you don't necessarily need to spend over $100 on one.

Other features

This is more of a bonus point, but some binocular harnesses have pockets or other features to provide extra storage. It can be nice to keep your rangefinder in one of these pockets while it is not in use, rather than just dangle it around your neck for anyone to steal.

These can be nice to have, but are they necessary? Let’s say that you have a sling style harness, which is great for comfort if you have to walk around the field for hours at time; however, this also means that it could easily be stolen by anyone who wants to take your binoculars. You could buy one with extra pockets or other features; however, there are probably better things to spend your money on.

This criterion was bonus points in the previous section, but here I am making this point number 4 because this is the one criteria that you should really care about. All of these other features may sound nice, but if they are not essential to your hunting then you don't need them. If you think about it logically, do you take binoculars on a hunt for anything besides looking at game? If so, then the only thing you need is a binocular harness that can hold your binoculars.

Style

You might think that style is important for something like this, but let me tell you from personal experience. I have had many different types of binocular harnesses, from wrap around to belt to sling style. What I found is that any one of them works fine as long as the rest of the criteria are met.

Weight capacity

I actually made this point number one because I feel like it is extremely important; however, some people might think that if their binoculars fit then it doesn't matter what the weight capacity is. The fact of the matter is that if you are carrying something heavy but your harness can only handle it for a few hours before you start having discomfort then that doesn't really solve anything does it?

I know that I made this point the very first thing you should consider, but here is the big warning. This is only really important if you are using your binocular harness for long periods of time or carrying an extremely heavy pair of binoculars. If it says 10 pounds, don't expect to carry 20 pounds for prolonged periods of time.

Durability

I'm not going to lie and say that the most durable thing in the world will break, even if it falls from a thousand feet in the air; however, I would like to think that the best binocular harnesses for hunting are at least moderately durable. Let’s not forget that your binoculars will probably be around for a while, so if you get something cheap and flimsy it is going to break on you sooner or later.

Return/Warranty

While this may seem like a pretty lame criteria it can be important to you. If you buy something online and realize that the product is not what you expected, then your chances of getting your money back are probably very slim unless it has some sort of warranty or return policy.
