S1 Helmets is stepping up impact reduction by adding an additional layer of protection to your helmet with our revolutionary new impact reducing sizing liner the RAD Liner. S1 RAD Liners are an impact reducing sizing liner that Reduce Absorb and Disperse impact energy away from the head when impacted. RAD liners serve a dual purpose by both acting as your helmets sizing liner while also adding an extra layer of impact reducing foam to your helmet.  Lab Tests show that depending on the impact RAD Liners reduced impact energy an additional 7.5% to 16.5% averaging a 12% energy reduction to the head in all liners tested. RAD Liners are sized just like our standard sizing Liners and fit into all S1 Lifer Helmets and are covered in a sweat absorbing, hand washable terry cloth fabric. S1 RAD Liners. Next Level Protection. ****SIZING NOTE**** The RAD Liners are made with a layer of rigid shock absorbing foam so will not compress as much as Standard Sizing liners or Terry Liners. Many users choose to go up a size from what they normally wear especially if you are right on the bubble of one size and another. If you are usually a Small for instance we suggest ordering a Medium. However in some instance users do prefer to stay in their original size. If you would like to try your normal size and a size up for comparison we are offering a free return shipping label for anyone who wants to order two sizes for comparison. Once you send the other sizing liner back we will refund your purchase of that liner.  Please make sure to send us a message in the notes box at check out to include a size comparison return shipping label and we will provide one for you. Please call or email us with any questions or concerns. RAD Liner Disclaimer DISCLAIMER: S1 RAD Liners reduce the risk and severity of head injury, compared to no head protection. Leading medical doctors, PhD’s and scientists have concluded that a reduction in impact energy to the head correlates with a reduction in concussion risk. You can still sustain a head injury even with head protection, and no helmet or impact reducing sizing liner can prevent concussions or eliminate the risk of these types of injuries. *** Installation Note ***  If you are adding these terry liners into a helmet that you have already worn please wash the contact points wear you plan to place the new Velcro with a wet cloth to wipe away any sweat residue that may have built up on the surface of the inner helmet shell.  Doing this will ensure that the Velcro will stick firmly to the inner shell.

Small means small

To small for 2 month German Shepherd. It was my bad for ordering a small. But I never saw product specs saying the actual size. Remember never buy a to small of toy for your puppy as it’s a choking hazard.

My daughter's lab kills any toy he gets. This was perfect! We accidentally left it in his kennel while out one day and it was still in perfect condition. Totally worth the money if you dog is a tyrant with toys!!

SAVE YOUR MONEY, THESE ARE UTTER GARBAGE UNLESS YOUR DOG HAS NO TEETH (MAYBE)!!
Size: Large, Product Packaging: Standard Packaging, Size: Large, Product Packaging: Standard Packaging
For all those purchasers who are posting videos of these toys while talking about how great they are and how long they have lasted at your house, would you mind disclosing the breed and age of your dog(s) that play with them? I only ask because I am finding these "positive" reviews REALLY hard to believe now that I have firsthand knowledge that, as a chew toy, this thing completely sucks. Based upon personal experience and the physical and photographic evidence, your dog might be an OBSESSIVE chewer, but they are most assuredly NOT a "power" chewer. If they were, you would almost certainly be posting reviews saying that this toy is utter crap, just like I'm having to do now. After many years of experience using Kong brand toys, the idea that this toy is the "most durable" Kong toy is just ridiculous, and blatant false advertising in my opinion. It took three of my dogs (a 5 year-old Boxer/Pit Bull mix (2nd pic) I'm fostering and two one year old border collie puppies) all of five minutes to completely shred FOUR of these toys straight out of the delivery box. I was the proud owner of four of these things for all of five frickin' minutes out of the box. Meanwhile, it previously took the Boxer/Pit almost two years to destroy two medium-sized Kong "snowman" shaped toys, and even then he wasn't able to shred them anywhere near to this degree. And believe me, he actually *IS* a true "power" chewer, as after raising and training dogs for over 50 years, I have never seen a dog completely break that type of Kong chew toy. As an aside, Kong (the company) appears to take crappy product claims only by means of printed hard copy sent via the U.S mail, so no immediate relief for your wasted expenditure on their products will soon be forthcoming. How many modern companies do you know of that don't allow some sort of online contact for product claims, even if it's just an email address? So I might very well have to reconsider whose products I am willing to spend my all-too hard earned money on. That said, those three dogs are all now outside throwing up chunks of these crappy toys that they swallowed while tearing them to pieces, and which I now find myself hoping really are non-toxic!! The regular "snowman" shaped Kong toys are MUCH more durable than these things are. Had I known that beforehand, I would have spent my money accordingly. The picture I posted is the last remaining toy out of the four I ordered, and I most certainly want my money back (wish me luck)!! This toy is a complete WASTE of your money for any dog that is bigger than an aged chihuahua or that actually has teeth, so I suggest that you DO NOT purchase.

The same magic as the extreme chewer Kong cone!
Size: Large, Product Packaging: Standard Packaging
My lab hound mix LOVES this tire as much as he loves his extreme chewer Kong cones (we bought three of those!). He hasn't been able to cause any damage at all in the week or so that he's had it. We are always excited to find toys that he can't break! We're ordering a second tire for upstairs!

Great training tool
I bought this for my working line GSD for training. It’s awesome. The rope isn’t too long to handle during training sessions but still long enough I don’t lose a finger when paying out. The Kong holds up well, as expected. The only concern I would have for anyone would be the integrity of the rope on a heavy chewed which is the reason for the 4/5 star review. If used as a freely available toy left unattended with a moderate to heavy chewer the rope wouldn’t last very long. But I do love it!
