Reviews
One K Defender Helmet Liner is rated 4.3 out of 5 by 7.
Rated 1 out of 5 by from Doesn't correctly attach to helmet - useless Was really excited about this, but sadly the snaps that go into my helmet do not stay put and the liner appears a bit longer than my helmet. I got an XL liner to go with my XL helmet. It is virtually useless.

Rated 5 out of 5 by from Fits great, So good to have one to put in washer when all sweaty! I put in washer bag with riding clothes. Fits my K Defender helmet.
Date published: 2020-02-27
Rated 5 out of 5 by from Perfect replacement! I bought this so I could wash my original liner and not loose out on a few days of riding. LOVE how fast it was delivered (ordered on Wednesday night after dinner and it was on my doorstep when I got home from work 2 days later on Friday)!

Rated 5 out of 5 by from fits great, washes great I bought a replacement liner as the one that came with my One K helmet was pretty gross from summer sweat/makeup. I swapped this out in seconds, took the old one home and threw it in the wash and its as good as new. happy to have a fresh one on hand when i need to swap them out.

Rated 5 out of 5 by from Love the removable liner I love the removable liner on the One K helmets. Our summers are very humid, so I purchased a second liner to always have a clean/dry one ready for the next ride. I'm planning to buy one the next size up for winter so I have room for my thin fleece headband. Very happy with the liners and the helmet.

Rated 4 out of 5 by from Amazing Quality I bought this to put in my OneK helmet I bought the XL size and It was a little too big for my head so I ordered this liner in the size large so I wouldn't have to put my hair in my helmet every time I rode. It works amazingly and is super easy to put it in the helmet and to take it out of the helmet.

Rated 5 out of 5 by from easy to wash!! I bought this extra liner so I would always have a "fresh" helmet. It's so easy to wash, I throw it in my washer and let it dry on my porch. It dries in no time and my helmet no longer smells! Great investment. I love it.
