IR4G and IR4G XLT, the IRH helmets riders ask about most
IR4G and IR4G XLT show helmets
IR4G and IR4G XLT are sized helmets with hook-and-loop liners and quick-release chinstraps.
What riders say about IRH helmets
I was hesitant to buy a new helmet but went with this one because of the matte finish. I LOVE it. I used it for the first time at Color Breed Congress in November. Fits great and I got so many compliments on it! If you are thinking about getting this helmet. DO IT.
Love this helmet! Looks and feels great. Very comfortable. I use it daily as well as in the show ring. Love that it comes with an extra insert for inside the helmet.
The fit is perfect and the helmet is really comfortable to wear.
True to size. Looks awesome on and is comfortable.
The IRH Edit
IRH helmets that fit long oval heads and look right in the ring
Six short sections cover the IRH lines, the long oval fit, switching from Charles Owen or GPA, sizing and liners, sun visors and brims, and who should shop elsewhere.
The IRH lineup
IRH riding helmets in five lines for show and schooling
The IR4G is IRH's show and schooling helmet, with rear and side ventilation, a hook-and-loop secured liner and a quick-release chin strap. IRH lists ASTM F1163-15 for it. The IR4G XLT adds ventilation ports front, top and back and ships with two moisture-wicking liners in different thicknesses.
The F1 Short Brim and F1 Wide Brim use a lightweight shell with a leather-like harness, and the Equi-Pro trades sizing for a dial fit system and a removable Cool-On-Lining. The Medalist Hunt Cap is the traditional choice: a velveteen outer, lightweight construction and a black three-point harness. Look elsewhere if you want a dial fit in a show profile, since only the Equi-Pro carries one. Browse them all in IRH riding helmets.
What Riders Say
I have worn a velvet hunt cap with an elastic chin band for showing for close to 20 years. For some time now i have also worn it while schooling so i would be accustomed to having in on. Recently i took a pretty hard dismount and undes up on the ground. As i was getting up I realized it was pretty stupid to wear a helmet that offered no protection. That night I began looking and found the international medalist helmet. It is more comfortable than my old hunt cap, offers protection and has a lot of ventilation. I hope i neber need it but feel a lot better wearing it
I ended up with an IRH IR4G XLT which is similar in style to the OneKs and I quite like it.
Long oval fit
IRH long oval helmets for heads other brands miss
Riders tell us the IR4G XLT is the IRH to try for a long oval head: one calls IRH the best fit for a long oval head with a taller crown, and another finds the XLT slightly more comfortable than a Samshield. Two liners in different thicknesses let you adjust how snug the helmet sits front to back.
The IR4G shares the same show-ring styling with rear and side ventilation, so compare the two by vent layout and liner setup. IRH's XLT chinstrap uses a quick-release hook-and-loop closure with a comfort harness cut away slightly at the back of the neck. Look elsewhere if you want a dial to adjust fit, since the XLT is sized and uses liners instead.

Switching brands
IRH helmets when Charles Owen or GPA won't fit
Riders tell us IRH is where they land when a Charles Owen or GPA stops fitting: one reports an IRH that fits perfectly while her Charles Owen and GPA do not fit at all, and another found newer Charles Owen models no longer suited her. Measure your head instead of copying the size on your old tag, because each maker sizes on its own chart.
Start with the IR4G XLT if your old helmet felt too narrow front to back, or the IRH riding helmets range to compare lines. Both come sized, with liners to refine the fit. Look elsewhere if you need a specific certification your current helmet carries and IRH does not list; IRH lists ASTM F1163-15 on the lines above.
What Riders Say
Sizing and liners
IRH helmet sizes and liner thicknesses that tune fit
IRH sizes its show helmets rather than using a dial, and liners do the fine-tuning. The IR4G XLT and IR4G take the IR4G & XLT replacement liner, offered as eight liners in four thicknesses. F1 helmets use the F1 replacement liner, made in a quilted moisture-wicking material in multiple sizes and thicknesses.
The Equi-Pro II and SV take the Equi-Pro II & SV replacement liner: the X-Small and Small/Medium liners are interchangeable in the X-Small and Small/Medium helmets, while the Medium/Large liner only fits the Medium/Large helmet. Match the liner to your helmet line before you order, and use the size chart below to pick your starting size.
What Riders Say
I like IRH because they are sized instead of a dial adjustment and I can get one to fit my pin head without looking as if I am balancing a pot on my head! Unfortunately they only come in black.
My helmet fits with my hair up and down, I tried it with my hair up, and again IT DOES fit me with my hair down
Shade
IRH helmets with a sun visor or wide brim for shade
The EQUI-PRO Helmet w/Sun Visor has a rounded visor for show, schooling or trails, a dial fit system, a front vent system and a removable, washable liner. IRH lists ASTM F1163-15 for it. The F1 Wide Brim is cut for the sunniest days in light footing, and IRH says its brim shades the entire face and the upper neck.
For a cleaner show line, the F1 Short Brim keeps a lightweight shell and a leather-like harness without the extra brim. Look elsewhere if you want a wide brim on a dial-fit helmet, since the F1 Wide Brim adjusts with liners instead. The shelf below pulls the brim and visor helmets together so you can compare them side by side.

Is IRH for you
Who IRH riding helmets suit, and who should look elsewhere
Riders choose IRH when they want a sized, lightweight helmet that looks neat in the ring. One rider bought hers because Troxels looked too big on her, and another finds hers lighter, cooler and more comfortable than her Troxel Sierra. The Medalist Hunt Cap and F1 Short Brim carry that neat look into the hunter ring.
The Equi-Pro suits riders who want to turn a dial for a quick custom fit and a Cool-On-Lining that pulls moisture away. The IR4G XLT and IR4G suit riders who prefer a sized helmet with swappable liners. Look elsewhere if you want MIPS technology, which IRH does not list on these helmets.

Questions riders ask
IRH helmets FAQ
Which IRH helmet fits a long oval head?
Riders with long oval heads often name the IRH IR4G XLT, which comes with two moisture-wicking liners in different thicknesses. Measure your head, check the IRH size chart, and shop the IR4G XLT to compare.
How do I choose the right IRH helmet size?
Measure your head about an inch above your eyebrows and match it to the IRH size chart for your line. IR4G, XLT and F1 helmets are sized, and liners come in several thicknesses to fine-tune the fit. Start with the size filter above.
Does IRH make a helmet with a sun visor or brim?
Yes. IRH makes the Equi-Pro Helmet w/Sun Visor with a rounded visor and dial fit system, plus the F1 Wide Brim, which its description says shades the entire face and upper neck. Compare both in the IRH helmet shop.
