Meet the all-new Propero 4 helmet—it brings the aero advantages of the S-Works Evade 3 together with the ventilation of S-Works Prevail 3, all with the comfort and confidence Specialized helmets are famous for, earning the highest 5-Star Virginia Tech® helmet rating. Every detail of the Propero 4 was created with our equation for speed in mind. Aerodynamics + Ventilation + Lightweight = Fast.

AERODYNAMICS: With extensive testing in CFD and in our Win Tunnel, aerodynamics were at the forefront of the Propero 4 development. We took the aerodynamic leading edge from the S-Works Evade 3 and pulled it directly into the Propero 4—which helped it to be four watts, or 15 seconds over 40km, faster than our S-Works Prevail 3.

VENTILATION: Drawing inspiration from our world-renowned S-Works Prevail 3, our goal was not merely to replicate but to elevate. Ventilation became a focal point in our quest for a well-balanced, aerodynamic, and ventilated helmet. We incorporated the rear-end design language of the S-Works Prevail 3 and introduced small 2mm offset micro-channels that create turbulence in the airflow throughout the helmet to help create a continuous, refreshing flow of air.

ATTENTION TO DETAIL: Beyond just aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by incorporating cutting-edge technologies from our S-Works level helmets, like MIPS technology for confidence, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations, it redefines them.

  • Mips Evolve Solution is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts.
  • Propero 4 earned the highest 5-Star Virginia Tech® Helmet Rating from internationally renowned Virginia Polytechnic Institute and State University.
  • FS3 Fit System & Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape, and helmet angle can be adjusted for compatibility with glasses.
  • Adjustable Tri-Fix web splitter combined with thin 10mm webbing for increased comfort.
  • Dedicated sunglass storage maintains a secure fit and keeps eyewear out of the way when needed.
  • Micro Channeling & large rear-end vents for increased ventilation.
  • S-Works Evade 3 front-end design language for enhanced Aerodynamics.
  • Precision, full-wrap polycarbonate shell for increased durability and premium finish.

Didn’t Last
Color: Blue
Cute toy and was fun for either quiet play or rowdy play. It didn’t last as long as I expected but it was fun for a while.

Will buy again
Color: Orange, Color: Orange
This was one of the first toys I got my dog and he LOVED IT. I sadly had to throw it away because he peed on it but this is something I will definitely repurchase. Perfect for tug of war and playing fetch. Definitely not indestructible as he did rip it a little but it took him a LONG time to do that

Perfect size for pittie pups
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
This was a pretty good toy. I have three pitbulls. The puppy in my video is 65lbs for reference to the toy. I thought that since it was fluffless she wouldn't try to eat the thing but after a couple of days of tugging it with her brothers the toy's paw came off and I was not fast enough to prevent her from swallowing it. She got rid of it with little GI stress. I will say that even though she's not squeaking it in the video, it has a pretty loud squeak. Overall we had it for four days before 260lbs of pooches were able to get the squeaker out. If you have pits then you know this is 5-star worthy sturdiness.

An Instant Hit and Everyone's New Favorite
Color: GREEN, Size: 14 inch (Pack of 1), Style: FROG
An instant favorite! It took quite a while for my dog to break the squeaker, too. I love that it uses a water bottle for the crinkle sound, and I'm kind of glad the squeaker finally bit the dust. That works out well for us. It's tough enough that it's not ripped yet. Our dog plays with this toy every day. No fluff to pull out was definitely a plus for me. It's a great toy for the price, and I think small and larger dogs would also enjoy it. Johan is 7 months old, weighs about 40 pounds, and always chooses a favorite toy. This one replaced a worn out toy frog that was smaller, but still treasured. I was so glad that he loves this one just as much. It's a little bit longer than a regular-sized water bottle and has dangly legs. I think you could also put plastic that crinkles inside it, and they would love that too. It has a velcro closure to keep whatever you put in there inside, and he hasn't figured out how to open it so far. Update: We just bought a second one of these because he enjoyed the first one to its conclusion. It lasted longer than most toys (about 4 months with HARD use by a giant puppy), and it is his most favorite soft toy. The original didn't rip or tear, but the velcro got worn out when he figured out how to open it. I probably could have fixed it easily, but since Johan is the goodest boy, I got him a new one.
