LeMieux Vexa® Riding Hats


Frequently Asked Questions

How do I measure my head for a riding hat?

Wrap a soft tape measure around the widest part of your head, roughly three-quarters of an inch above your eyebrows and just above your ears, following the curve at the back of your skull. Take the measurement twice for accuracy, and tie back long hair first. The LeMieux Vexa riding hat comes in Small (52–55cm), Medium (56–58cm), and Large (59–61cm), so match your reading to the closest shell size.

How often should I replace a riding hat?

Most manufacturers recommend replacing a riding helmet every five years from the date of purchase, even without a fall, because the internal foam and shell materials degrade with sweat, heat, and sunlight over time. Replace it immediately after any impact, however minor, since the protective structure may be compromised even without visible damage. Frequent competitors often replace helmets sooner, every two to three years.

What's the difference between a skull cap and a riding hat?

A skull cap has a rounded, peakless shell, while a traditional riding hat has a fixed forward brim. Both styles can meet identical safety certifications, so the choice comes down to discipline and preference: skull caps suit cross-country and eventing, where a fixed peak risks injury on a fall, while peaked hats are common in dressage and showing for a traditional look.

What safety standards does the LeMieux Vexa meet?

The LeMieux Vexa riding hat is certified to EN1384:2023 and ASTM F1163-23, carrying both the BSI kitemark and SEI certification. The corrugated ABS twin shell and reinforced polycarbonate rim resist impact, penetration, and crush forces. The design also earned a 2026 Red Dot Award, recognising the balance between certified safety and everyday comfort.
