One K Defender Bling Helmet is rated 4.7 out of 5 by 23.
Rated 3 out of 5 by from Beautiful helmet, strange fit for me I LOVE LOVE LOVE the look of One K helmets, they are absolutely beautiful and look great on a lot of people. However, I'm not one of those people! I have mushroom head in this helmet..lol. They look great on so many people I'm so sad to return it...

Rated 3 out of 5 by from Beautiful helmet..but I bought this helmet at the end of 2020 to replace my old Charles Owen. It is my daily helmet, but also looks great in the show ring. I only ride one horse and ride about 3-5 days a week. It does not get used for more than an hour or two per day. It fits great and is a beautiful helmet. I am so disappointed that after only 8 months of riding in it, the suede is bubbling up near the brim. I have never ridden in the rain nor got the helmet wet it stays in my tack room that is temperature controlled. Before I was raving about the helmet, but now I just want to warn people that the suede can bubble up and be unflattering.

Rated 4 out of 5 by from Beautiful helmet, but long oval is still too round This helmet is lovely - classic with just a little extra bling to make it stand out. I have been trying different helmet brands that are more oval and don't give me a bobblehead appearance. Ordered this in long oval, however it is still too round and gapes considerably on the sides, fits snug front to back. Disappointed that I have to return it!

Rated 5 out of 5 by from Very comfortable! This helmet is stylish, comfortable and lightweight! No bubble head! I forget I'm wearing it! It's cool in the summer and I love the removable liners that let me wash them and customize the fit!

Rated 5 out of 5 by from Beautiful Helmet but doesn’t fit ! There seems to be a problem with One K Defender and their helmet fit between BLACK and NAVY. I have the round version (also bling) in BLACK that fits perfectly. I wanted to have a NAVY helmet: My 1st order was a MEDIUM round. It came—it fell off. My 2nd order was a size SMALL. Way too tight. 3rd order I decided to try the OVAL to see if that would fit. It arrived today and it fell off to! I don’t get it, the black ones in medium fit great!

Rated 5 out of 5 by from Bling Helmet Love this helmet. Very pretty dark blue color, Swarovski crystals add sparkle without being over the top. I have a small head and very fine hair; the small needed to be pretty small, and it is, fits perfectly. My head circumference measures 21 1/4", 54cm, hat size 6 3/4, as measured just above the ears. The padding inside makes this helmet very comfortable and keeps it in place. It's winter, so hard to say if the vents will keep the helmet cool. Two small vents are located on the front, acting as kind of a scoop to draw the air in and two large vents, one on each side, should be enough that it will stay cool.

Rated 4 out of 5 by from Great helmet I love the One K helmet- I recently needed a new navy helmet, and knew exactly which one I wanted. (I also have one in brown!) The only issue with the new one is that the chin strap seems to want to ride up unless it is very snugly fit. Hoping that it relaxes with time.

Rated 5 out of 5 by from Great Helmet One K helmets are awesome! They are well made and look great!
Date published: 2017-07-13
Rated 5 out of 5 by from So Comfortable I have been waiting and waiting for a helmet to fit this well. For me, the helmet fits perfectly behind my skull / neck where if there was to be an accident, my head is covered on all sides. One K specifically tells you "what" products make up their helmets. That was another big selling point for me. The bonus is the colors and bling.

Rated 5 out of 5 by from Great fit and very showy! I bought the helmet for shows and get many compliments on it!
