Why a harness instead of a neck strap
Vortex Optics says traditional neck straps for binoculars may cause strain and fatigue, leading to a sore neck. A harness, in the same Vortex guide, distributes the weight of the binoculars across your shoulders and upper body.
That matters most with a 10x42 or a 12x50 on a long walk. A harness only works if the pocket matches the body of the binoculars, so the printed fit figures decide the choice.
Harnesses that print inside measurements
Two makers print pocket dimensions. The Marsupial Gear Enclosed Binocular Pack Small measures 6.7 in tall, 5.75 in wide and 2.75 in deep, and the maker says most 10x42s fit it. Medium is 7.75 in tall at the same 5.75 in width and 2.75 in depth, for most 50mm models.
Large grows to 8.75 in tall, 6.25 in wide and 3.25 in deep, for most 56mm models. Marsupial Gear states that none of the three sizes fits Porro prism binoculars.
The Alaska Guide Creations Kodiak Cub Gen L Binocular Harness Pack is 6.5 in tall, 6 in wide and 3 in deep. Its maker meant it for objectives up to around 42mm, and lists the 8x32 and the 8x42 along with the 10x32 and the 10x42. The Sitka Flash Optics Harness is designed for 8x and 10x binoculars up to 6.75 in tall.
Harnesses sized by model list or objective
The Badlands Bino Mag will accommodate binoculars up to 12x50mm, so its limit is a 50mm objective. That covers a 12x50 and anything smaller.
The FHF Gear Pro-M Bino Harness comes in four sizes. Small is listed for 42mm models such as the Nikon Monarch 10x42 and the Swarovski EL 32. Medium covers the Vortex Crossfire 42 and 50 and the Swarovski EL 42 and EL 50. Large lists the Vortex Razor UHD 12x50 with eyecups in and the Zeiss Victory HT 10x54. Chest Rig covers 56mm models such as the Zeiss Conquest 56 and the Leica Geovid R 15x56.
The FOB Bino Harness from FHF Gear has Standard and Large. Standard lists the Razor HD 10x42 and 12x50 and the Viper HD 10x42 and 12x50. Large lists the Leica Ultravid 12x50 and the Forge 15x56, as well as the Razor UHD 18x56 and the 20x56 Monarch 5.
Matching a harness to your binoculars
Start from the objective size. A 42mm pack suits a 10x42 or 8x42. A 10x50 needs a 50mm pack, and a 15x56 or 18x56 needs the 56mm size.
Then check the pocket height against the maker's figure for your model. Where a maker prints only a model list, find your exact model on it. Eyecups matter: FHF Gear lists some Vortex Razor models as fitting with eyecups in.
