Question: What color straps does the navy come with?  Also, can I get the cup strap instead of chin strap
Document: this is a really great protector for jiu jitsu. The only issue is the neck strap chokes you and that is the opposite of what you want in jiu jitsu. If you search for Chin Cup Strap for Cliff Keen Wrestling Headguard the appropriate strap will come up. Wear that in order to not be choked.Also if you tape the two straps up top together it prevents the front strap from coming down over your eyes.
Love the headgear. You can hear really well in it and easy to adjust (i crossed the straps on top). I purchased this item in white and i will be purchasing the chin cup strap for it.
Headgear is fine ... but the package did not include the chin strap... I need to get this resolved soon for my son.
We ordered two different models of Cliff Keen headgear - the E58 and the Twister model, both available here on Amazon.The E58 has soft, protective ear cups that allow hearing through the holes, but we didn't like the hard plastic straps or the plastic chin strap pad. The straps all adjusted well, but it just wasn't as comfortable as the Twister.The Twister had heavy duty, wide nylon straps, and a softer chin strap pad, which makes it more comfortable to wear.
The one downside i had about this was that it was annoying to adjust, but once i got it adjusted it was great. I would also recommend that while your adjusting it make sure you cross the top two straps, it will keep the straps from sliding and will fit more comfortably.
I use the E58 headgear for bjj.I went with this over the other more modern-styled headgear(the twister and the tornado) because of the softer shell and the rubber straps.It is very easy to clean, modular, and light. The profile is also much lower than I thought it would be. It does shift sometimes in hard rolling.It is a pain to resize but it really only needs to be done once.
Did not include a chin strap. Package definition was not clear. Disappointed when received. Price was more than it should have bee
I use this headgear for gi/no gi bjj and it's been treating me very well. The design and the material is great, it's easy to clean using alcohol wipes and a damp paper towel. The only thing that is a pain to deal with is the initial adjustment, it seriously took me forever to get it to the adjustment that works well. Other than that, it's perfect, protects your ears while also making sure your opponent doesn't sustain any damage.
The headgear came in and was great. It was the right color, right fit, and great quality. I would order again
I bought this as a gift for my grandson who is a high school wrestler. He is very pleased with the headgear. It is comfortable to wear and gives him the protection he needs. Additionally it was offered in his school color.
