DIY bino harness I made based off of a post in the DIY section here.
Can’t find thread, but it’s 2” wide elastic webbing, doubled over, with slots sewn in for binos and rangefinder. Then a single 1” elastic band loops over back of 2” webbing behind you, up to your bino lanyard. Regular ole adjustable click buckle under armpit.
Weighs nothing, nothing sticks out past front of your binos which is great for archery.
Only downside is no dust cover, so riding atvs or some other dust creating activity while hunting leaves you cleaning glass.
