Spatzwear Windsock PRO Aero Oversock – Black

The Spatzwear Windsock PRO is a race-ready aero oversock engineered to push performance beyond the already proven Windsock2 platform. Worn to victory in Tour de France stages, major Classics, and the UCI World Gravel Championships — and used by Mathieu van der Poel at Omloop Het Nieuwsblad 2026 — the Windsock PRO is the choice of the world's fastest riders. Available here in a sleek, versatile Black colourway.

Wind Tunnel Tested Aerodynamics

Developed for maximum efficiency in fast race conditions, the Windsock PRO was tested at the SSE Wind Tunnel Hub, delivering consistent CdA reductions over the standard Windsock across most yaw and speed angles. Every detail — from the aerodynamic lycra leg section to the striated ankle fabric — is shaped to reduce drag and keep you faster for longer.

Waterproof, Secure & Built to Race

A waterproof stretch main panel protects against wind and the elements, while the super aerodynamic lycra leg section delivers a close, stable fit. The newly developed internal gripper system ensures the oversock stays exactly where it should, lap after lap.

Features

  • Advanced aero oversock developed from the proven Windsock2 platform
  • Wind tunnel tested for improved aerodynamic performance (SSE Hub)

Flavored Dog Rubber Balls
Color: H) 2.5" 3-Pack (Beef), Color: H) 2.5" 3-Pack (Beef)
My dog absolutely loves these balls, I have a few more I had already bought, but she has an addiction to them so I had to buy more. I am able to squeeze these really easily so when she does pick them up after I’ve thrown them they’re very easy for her to pick up. They have a good thickness to them so it’s not too flimsy. It’s pretty tough and they bounce pretty high which I like and so does she know she is an aggressive chewer, but I haven’t had an issue yet with her chewing right through these, which is why I like them and we both love the fact that it smells like beef I could practically smell them through the bag, but I have a really high pitched sense of smell, and I knew she was going to love them. Not to mention you can’t beat the price.

Love These Balls
Color: H) 2.5" 3-Pack (Beef), Color: H) 2.5" 3-Pack (Beef)
These are great balls. My Border Collie can destroy a tennis ball in a couple of hours and the Kong brand ball is heavier than I like to play with in the house. These balls hold up to her biting and chewing but are lite weight and softer for bouncing off the walls.

Seems durable - but the scent is not the best
Color: B) 3" 2-Pack (Bacon)
I don't know if I'd call the scent of this "bacon," more like rubber with a hint of bacon. It's very strong. I gave my dog one of the balls & put one in a cabinet where I keep his treats & a few other unrelated odds & ends. I now hold my breath when I open that cabinet b/c good lord, the smell. I'm tempted to just give that one to the dog too, just because it'll air out eventually & then everything else in that cabinet won't smell bad. My dog feels so-so about it. He'll briefly chase after it & chew on it, but loses interest in it pretty fast. My rather hyperactive cat also plays with it from time to time, as he seems to have more interest in most dog toys than the dog these days, so there's that. (Then again, he thinks a wide variety of random items around the house are loads of fun to toss about, so it's possible his opinion is to be taken with a grain of salt. Between the brief periods of one of these balls being chewed on & clawed at, it's stayed completely intact. I think if you have a dog who simply likes to play fetch or chew on rubber balls in general, this one would stand up to the task. But if you're expecting it to be greeted with the enthusiasm as a bacon grease covered ball might be - I'd adjust your expectations.

My dogs favorite toy so far in two years
Color: C) 4" 2-Pack (Bacon)
I use this with my medium sized dog. These are large for him but that's what I want so I don't ever have to think about them being too small or a swallow hazard. He has been through A LOT OF TOYS in the last couple years, but nothing, NOTHING has he loved as much as these. His favorite used to be squeaker balls. Then his favorite was crackle balls. But he will gladly ignore both for this one. I don't know if it's the bacon flavor or what, but he go nuts for it.
