Imperial Riding Trail Ride Fly Mask Size Guide

Use this size guide to find the correct fit for the Imperial Riding Trail Ride fly mask. Sizing follows IR's standard horse-size categories — Pony, Cob, Full and X-Full — and the dimensions below describe the mask itself in cm.

How to measure: measure your horse's head from the front of the noseband to behind the ears for length, and around the widest part of the cheek for circumference. The mask should sit clear of the eyes and nostrils, with the ear openings centred on the ears and the throat strap snug enough to stop the mask shifting in wind.

• A — mask length (front to back)
• B — circumference around the throat opening
• C — circumference around the nose opening
• D — circumference around each ear opening
• E — ear height

All measurements in cm. This guide covers the Trail Ride model (with and without nose). Other Imperial Riding fly masks — Activity, Careful, Carly UV, Fly Shield — use a different cut and aren't covered here; refer to the individual product page for those.
