Measuring your Head

2. Have someone esle measer your head for better accuracy

3. Measure all the way aorund your head as shown

4. Place the measuring tape 1″ or 25mm above eyebrows just above your ears

5. Measure over your hair as your head will fit in the helmet

6. Take several measurements and use the largest reading

To work properly, an Armis helmet must fit right and be worn properly. In order to offer you the best value and fit possible. There are 2 main sizes with a range of removable headbands that adjusts the helmet size to fit to your head. The Armis helmet is available in the following sizes:


Medium: Large:
56cm (6⅞) 60cm (7⅜)
57cm (7) 61cm (7½)
58cm (7⅛) 62cm (7⅝)
59cm (7¼)

Step 1: (Sizing your helmet) – In order to determine the size you need, you can measure the circumference of your head. Simply wrap a measuring tape around your head, being sure to locate the tape just above your ears and keeping the tape level front to back. Once you’ve determined the proper size, you can check to make sure the helmet fits correctly. If the helmet you own now doesn’t fit on your head with just a little room between your head and the headband when the fit system is loose, you should replace it with one that does. You should always wear the helmet positioned low enough in the front to protect your forehead, but not so low that it hinders your vision. Once you’ve got a helmet that is the right size, and positioned it properly, you can adjust the fit as follows:


Step 2:  (Adjusting your helmet) Adjust the fit of the harness whilst wearing the helmet.  Insert the buckle on the end of the chin strap into the clip on the harness. To tighten the chin-strap, pull the slack downwards through the buckle and then adjust the rear straps, until the helmet is firmly positioned on the head. To undo the chin strap squeeze the clip together with your finger and thumb on the buckle clip to trigger the release mechanism.


Step 3: (Checking the fit) – Once you think the proper fit has been achieved, grab the helmet with both hands and twist it to the left and to the right. If the helmet fits properly, the skin on the forehead will move as the helmet moves. If it does not, the helmet is too loose. Also, grab the helmet with both hands and try to remove it by rolling the helmet forward and backward as far as you can. Make a serious effort. THIS IS IMPORTANT. If you can roll it off the head completely in either direction, roll it forward so far that it blocks vision, or backward far enough to expose the forehead, it doesn’t fit correctly. If you cannot adjust the helmet to fit properly according to these instructions, DO NOT USE THIS HELMET. Replace it with a different size or model. Once you are satisfied that the helmet fits correctly and that all straps are properly adjusted and tightened, take a short test ride. Pay attention to overall comfort and helmet stability while riding. If you have questions about fit, please contact your retailer who will deal with you directly or e-mail us at info@armispolo.com


Correct Fitting

The helmet fit should be level on the head and the harness correctly fastened. The helmet should not easily “roll” forwards and backwards. This helmet is manufactured to PAS 015 2011 & VG1 01.040 2014-12.  For adequate protection ensure that it is the correct size and fits snugly. Helmets can move more on your head when riding. In order to ensure that the helmet remains in position during riding, adjust the retention system to ensure that the movement of the helmet on the head is minimal, both for front-to-rear and side-to-side movement This helmet maybe partially destroyed or damaged by a severe blow, even though such damage may not be readily apparent. The helmet may after receiving an impact be damaged to the point that it is no longer adequate to protect the head against further impacts. Any helmet subjected to a severe impact should be replaced by a new one, as a subsequent impact may not give the wearer such adequate protection. No helmet can protect the wearer against all foreseeable impacts and under certain conditions riding accidents can lead to death, serious injury and long term disability. Helmets are not designed to protect the head in the event of crushing by a horse.
