Overview

Why We Love This

The ever popular One K Defender now with MIPS technology.  Founded in 1996 by a neurosurgeon and a researcher from the Royal Institute of Technology in Sweden, MIPS stands for Multi-directional Impact Protection System and is designed to add protection against rotational motion transmitted to the brain from angled impacts to the head.  MIPS added protection has been independently proven to reduce rotational motion by redirecting forces that would otherwise be transmitted to the brain. One K MIPS helmet features black matte Polycarbonate and Advanced ABS Composite outer shell; injection molded shell design; washable quick-dry, moisture wicking, anti-microbial liner;  and comfort padded harness with synthetic suede lining, hook & loop adjustment, and Fastex buckle; two front, one back, and two center stripe vents. For best care, wipe down with a clean, damp cloth for dust or dirt;machine wash removable inner liner. Compatible with the CCS Custom Color System.

Personalize your helmet with the CCS system by One K! With the custom color system (css), you can choose your One K CCS Front ShieldOne K CCS Top Panel and One K CCS Vent Stripe Rail. Change one piece, two pieces or all three to suit your style!
 

Imported

CAUTION: Safety equipment must fit properly and be appropriately secured with manufacture approved parts only. Altering or adding to safety equipment voids warranty and can result in injury. As a safety precaution, inspect all products prior to each use.

One K Defender CCS MIPS Helmet is rated 4.8 out of 5 by 26.
Rated 5 out of 5 by from Great fit! Great features and looks smashing. My husband surprise me with the OneK for my birthday.

Rated 5 out of 5 by from Love the fit! I am so happy I found this helmet. I am looking forward to my first ride with it. But the fit is perfect. The option for round or oval sizing made all the difference in getting it right.

Rated 5 out of 5 by from No more giant pumpkin head! Helmets are, of course, not one size fits all. For my very oval shaped head, One K comes through with the long oval shape! I no longer look like a hot air balloon trotting around my barn. It also is lightweight and looks classy.

Rated 5 out of 5 by from Great helmet We are very pleased with the quality of this helmet. My daughter says it feels great. Loved the storage pouch as well

Rated 5 out of 5 by from Well made and comfortable I needed long oval- it was backordered but came a month early! Really nice helmet. I show in the hunters and the eq.
Date published: 2021-06-30
Rated 4 out of 5 by from Excellent I bought this helmet because of the MIPS rating and the matte exterior. I am very happy with it. I gave it 4 starts rather than 5 because the material of the strap rubs a little under my ears and on the jawline...It may need to have a softer material wrapped around it. otherwise, excellent choice!

Rated 5 out of 5 by from Great Helmet This helmet5 fits as advertised. Good for an elongated head
Date published: 2021-04-20
Rated 5 out of 5 by from Love my helmet! I just got a new MIPS version of my old helmet. I love the comfort and fit, and have had no complaints over the past 5 years with my old one. I'm happy at the additional safety features and look forward to wearing it for years to come.
Date published: 2021-03-31
Rated 5 out of 5 by from Best looking MIPS helmet Bought recently, and fits great, in my opinion, the M fits the same as the OneK defender in M, super comfy and definitely has the nicest profile of the MIPS helmets out there.
Date published: 2021-02-23
Rated 4 out of 5 by from Not for me but give it a try One of three (Charles Owen & Trauma Void were the other two) I tried. I’ve had two Charles Owen Wellington (velvet 6 7/8) helmets over the last 5 years and wanted the new MiPS technology and good ventilation. This One K in oval shape was too loose, but if I still had my long thick hair it probably would have been perfect!

Rated 5 out of 5 by from Fits Well Got this helmet for my daughter. I did research about when to replace your helmet. I really like the MIPS added protection
Date published: 2020-10-14
Rated 5 out of 5 by from super helmet Fits EXACTLY right!! Looks fine and has the MIPS feature I wanted.
Date published: 2020-09-04
Rated 4 out of 5 by from Upgraded to MIPS I recently had a run-in with a tree wearing my old One K Helmet. Following the adage that when the head goes boom, the helmet goes buh bye, I decided to upgrade to MIPS technology The helmet seems pretty much the same except for a slim plastic layer between the liner and the helmet. It's a pricey piece of plastic, but I guess my brain is worth it if it really works. I wore a M in my old Defender and the M in the MIPS felt slightly snugger so I also ordered a L to compare. L was definitely too big, but the M still feels a tad snugger than my pre-MIPS medium. Maybe it's simply because my liner had squished down over time. I gave this a 4 simply because of price and maybe a slight size difference (I wish there was a M and a half). I look forward to being able to use the Custom Color System and the Snap-On Sunglasses when I can find them available for purchase!
