HELMET FEATURES
The SM5 helmet has been designed to provide MX riders with a helmet that is safe and purposefully designed to deliver optimal protection and comfort. The lightweight SM5 helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight, while the five density EPS liner ensures the correct density in the correct area for enhanced impact absorption.
- An engineered raised area with padding effectively reduces the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
- Revised the medium, large, XL, and 2XL lower shell volume to be around 3% wider to make the helmet easier to put on and take off, where the increase in helmet volume has also improved the impact management performance which is now 44% lower than the regular-speed threshold.
- For the new ECE 22.06 standard, the SM5 achieves a 44% better regular-speed impact rating compared to the current 33% figure, as well as a 32% better low-speed, and 31% better high-speed linear impact score than the prevailing standard.
- Multiple density inner liner to ensure the correct density in the correct area for enhanced impact absorption.
- Redesigned chin bar’s new profile, where the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury.
- Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports.
- The ECE version of the SM5 helmet weighs 1,350 grams for a size medium, and 1420 grams for the ECE DOT version with shield.
- The visor has been designed to direct air into the ports for enhanced airflow.
- The SM5 is available in 2 versions ECE R 22.06 and ECE R 22.06/DOT.

I like it, but
Flavor Name: Wishbone, Size: Large
Two large dogs, two different experiences. They both loved the toy, but one chewed it up within a couple of weeks - much longer than most toys last for him. The other one still loves it and uses it daily,(has had it for two months) but if I don't trim off the sharp points that form, it gets blood from his gums on it. Would still recommend it as each dog is different. Worth a try.

Overall a really great toy for all sizes of dogs
Flavor Name: Original Jerky, Size: X-Large, Flavor Name: Original Jerky, Size: X-Large
I ordered this product on Thursday and it said that it was going to be at my house in a week , but to my suprise it got delivered on that Saturday. My puppy loves these nylon bones. She is a 12lb dog but I ordered the X-Large size, and she loves it! The nylon bones really work in keeping her teeth clean of tar for the most part, and she loves the flavoring inside. The only downfall is when she got to the marrow part it stained my light sheets. I replaced them with darker sheets and there is no trace of the bone. Overall a really great toy for all sizes of dogs!

The ONLY Bones/Chews Dog-Approved in Our House!
Flavor Name: Original Jerky, Size: X-Large
We have 2 purebred pitbulls, both adult males who weigh between 75-80 pounds. We bought a huge assortment of bones, treats, and chews when we first got our boys (they're rescues, and we got them at the same time). They strongly favored these Marrowchews, even over other, imitation products of different brands.
We actually didn't know they had marrow INSIDE the bones for quite some time, and as soon as we realized that, we understood why our dogs loved them so much! The way the marrow is embedded in the bone, but a ways in from either end, is really clever. The dogs can surely smell it long before they can taste it, and it seems to keep them really interested and motivated at first. Then, they get to the actual marrow, and they are working on these bones non-stop until it's completely gone. The way they are made is also really unique; they sort of 'splinter' as they get chewed, and it actually helps with doggie dental care, cleaning the teeth and massaging the gums. There is no mess with these bones, no pieces flaking or chunking off, anything like that. They are also completely odor-free. With other bones/chews, they'll start them, but lose interest really quickly, and never so much as look at those again. These specific Marrowchews are truly the ONLY ones that keep our dogs interested, and for a significant amount of time, too. They'll work on the XL sizes daily throughout the day for a total of 1-2 hours, and they last a couple of months, easily. And keep in mind, these are pretty
aggressive chewers!
HIGHLY recommend these, and the price on Amazon is the best anywhere!

Durable and fun
Flavor Name: Beef, Size: Medium/Large
I have two dogs and I only bought one bone over a month ago. They’ve both been chewing on it and it’s held up really well. I wouldn’t say they’re aggressive chewers, but they do like chewing.
They’re still picking it up and using it, so they’re definitely not bored with it. As for me, it’s been a pretty great buy.
