Extra Large Helmets

Do any of your riders have a head so large it doesn’t your normal helmets? It’s not an uncommon problem. I’ve read about it in multiple forums, and recently had a reader ask for helmet recommendations for this. I didn’t have a good answer off the top of my head, so I thought it would make a good blog post to research and compile the responses. This is not comprehensive, but gives you a good start. Please leave comments at the end if you have anything to add!

We’ll start with some context.

How To Measure Your Head For a Helmet

Basically, you measure around the person’s head and record the diameter, which corresponds to a helmet size. Read this article for more info.

Understanding Helmet Sizes

Measuring is the easy part. Knowing what helmet size to get can be complicated:

  • for head size, some companies use inches while others use centimeters
  • for helmet size, some companies use numbers (7, 7.5, 7 3/5, etc) while others use words (SM M L XL; or S/M and M/L; or S/M and L/XL)
  • the sizing chart (relationship between head size and helmet size) is often different per company (example: IRH says a 7 3/4 helmet is a 24 inch head, while Troxel says it’s a 25 in)

However, there is a general continuity across most helmets. I think Ebay has a good list of head to helmet size correlations. Here is their list for what is usually sized Large and up:

  • cm          in           hat size
  • 57 cm    22 in      7
  • 58 cm    22.5 in  7 1/8
  • 59 cm    23 in      7 1/4
  • 60 cm    23.5 in  7 3/8
  • 61 cm    24 in      7 1/2
  • 62 cm    24.5 in  7 5/8
  • 63 cm    25 in      7 3/4
  • I would add
  • 65 cm    25.5 in  8 (for Charles Owen helmets)

So that gives you some idea about how head size and helmet size relate and are figured out.

Helmet Brands Size Large

For a list of all the sizing charts for helmet brands, see Dover Saddlery’s Helmet Manufacturer Sizing Charts. It’s really a great page, I hope they keep it up to date. I took the largest size for each brand according to Dover’s chart and put them in order from smallest-large to largest-large:

  • Brand                  in           cm         hat size
  • Tipperary:          22 ¼      56.5       7 1/8
  • Aegis:                  23.5       59          7.5
  • Uvex:                  24          60-61    XL
  • IRH:                     24          60.9       7 ¾
  • GPA:                    24.4       62          7 5/8
  • Samshield:         24.4       62          7 ¾
  • Troxel:                25          63.5       7 ¾
  • Charles Owen:  25.5       65          8  <— Pricey, but the biggest one out there I found

The Extra Extra Large Head

The problem is, some people have even bigger heads than the above! I read people asking about 27-28 in heads. Yet there are barely any helmets that reach a size 8, much less ones that don’t cost $200+. (Someone needs to cache in on this niche, because there’s a market there, albeit very small).

Here are the helmets people listed on the forums as the ones that worked best for large heads:

  • Devon-Aire Ussepa – L/XL is 7 – 7 1/2 helmet size, 21 7/8 – 23 1/2 inches head size (so not as big as many above)
  • Troxel Spirit XL  – multiple mentions. One person saidTroxel made a custom extra long strap on it for them.
  • Tipperary Sportage – multiple mentions. This is what we have, and it fits most of our riders but is not as wide as Troxel for those rounder headed riders.
  • Charles Owen Skull Cap (didn’t say which kind, but here’s an example) – multiple mentions. Expensive.
  • Charles Owen Wellington Classic Helmet or the Charles Owen Pro Helmet – it does come in 8 but many websites don’t carry it. Expensive.
  • One K Helmets – Their website says XXLarge is 61-62 cm, helmet size 7 5/8 – 7 3/4, and that it’s ASTM and CE EN standards but doesn’t mention SEI certified. However on the Smartpak website it is called ASTM/SEI certified.

Other Thoughts

  • “I contacted Charles Owens and told them about our center, and they kindly sold us a helmet at a reduced price.”
  • “I corresponded with several companies and all said that any new helmet would have to go through testing that would take months and be cost prohibitive.”
  • Troxel helmets run a little larger and seem to have more room on the sides for rounder heads.
  • The rider gets their own custom made medical helmet, doctor approved for therapeutic riding.

About that “Alternative Helmet Use” – there’s PATH Intl. guidelines for that, if you’re into that kind of thing 😉 A few notes from the Standards:

  • Alternative helmet use is only allowed under very specific extreme circumstances (see the Standards for a list)
  • First choice is a ASTM-SEI equestrian helmet
  • Second choice is a CPSC bike helmet or ASTM-SEI helmet for another sport IF it covers the head adequately
  • Third choice is a non ASTM-SEI or CPSC helmet made of rigid or soft flexible foam, from a therapeutic equipment supplier, another sport, or custom made – use with extreme caution!
  • Alternative helmet use participants MUST have written evaluation/justification by “an appropriate licensed/credentialed health professional (PT, OT, SLP or MD)” that states the risk and need for helmet and recommends which type to use
  • Alternative helmet use participants MUST have a leader and two sidewalkers, stay within an enclosed and safe arena during activities and therapies, and be directly supervised by an occupational, physical or speech-language therapist (so if you don’t have a PT/OT/SLP on staff and there with the rider, you can’t do it!)

SO, I want to know, what helmets have YOU found to work for your large headed riders? What’s been your experience? I know at least one reader who would really appreciate your response!

  1. When I was looking for a small helmet, I found the Ovation Schooling Helmet, XXs-xsmall. Along with helmet safety goes proper helmet fitting. When I attend different PATH events or go to shows, I always notice that the majority of helmets are not fitted properly. We need more education like this! Thank you!

    • Thanks and I agree!!! I hate seeing a tippy helmet on the front cover of a magazine or promotional material!
