FOB Bino Harness Sizing GuideUpdated 17 days ago
Length of binocular is the most important factor in determining a proper fit, including a tight seal over the lenses. We recommend measuring your binoculars after adjusting eye cups to your preferred position for accurate length and sizing. The size listed is the smallest option with eyecups adjusted in. Consider going up a size with eye cups out and/or large objective glass.
