Frequently asked questions
Find clear answers about this product, from choosing it to putting it to use.
How do I choose a C21 size?
MIRA lists chin-to-brow measurements of 5.19–5.51 inches for Small, 5.51–5.82 inches for Medium and 5.82–6.14 inches for Large. Use the manufacturer’s fitting instructions and verify the seal; size selection alone does not confirm fit.
Are filter cartridges included?
No. The C21 accepts compatible 40mm NATO threaded cartridges, which are sold separately. Choose a filter appropriate to the intended application.
Which harness and visor accessories are supplied?
The listing includes a six-point fabric harness plus clear and sunlight visor outserts. The rubber harness and other optional outserts are sold separately.
Can I choose the filter-port side?
Yes. Select the left- or right-side configuration shown in the product options. Follow the manufacturer’s instructions for any later connector changes.
