Measuring Guide


A person 's body measurements are shown in red.

Vest sizing is determined by 3 different measurements: height, chest circumference, and waist circumference. All vests have an adjustable waistband and will fit a range of height, chest, and weight measurements.

If you plan to wear your Hit-Air vest over a hard protective vest or heavy outerwear, sizing measurements should be taken over the hard vest or outerwear.

Size charts for each vest model can be found on the product pages.

Which Hit-Air Vest is Best for Your Body Shape

We have three "square cut" adult vest models - the Hit-Air Original, the Hit-Air Pro Plus, and the Hit-Air Pro Max. Square cut vests tend to fit shorter, curvier torsos better than other models.

We have two "rectangular cut" adult vest models - the Hit-Air Advantage and the Hit-Air Advantage Max. Rectangular cut vests tend to fit longer, straighter torsos better than other models.

How To Determine Your Body Shape: If your torso width is equal to or more than half of your torso length, a square cut vest is likely best for you. If your torso width is less than half your torso length, a rectangular cut vest is likely best for you.

How To Attach Your Western Lanyard

CORRECT - You are ready to ride!



Adjustable Bungee Lanyards and Western Coiled Wire Lanyards must be adjusted before use. A properly adjusted lanyard should be long enough for the rider to move freely and comfortably in the saddle but short enough for the vest to deploy and fully inflate before the rider hits the ground in the event of a fall. The rider should NOT be able to stand next to their horse while their vest is clipped into the lanyard and attached to their saddle.

INCORRECT - Lanyard is attached to the saddle D-Ring



Lanyards should always be attached directly to a solid anchor point such as a Saddle Strap, Saddle Horn, or Saddle Pommel. Saddle D-Rings are NOT a solid anchor point and lanyards should not be attached to them. Attaching a lanyard to a D-Ring may result in the D-Ring pulling out of the saddle and the vest failing to inflate during a fall.
