What people are saying?

One reviewer states, “The outside of the speed sac is durable, like a tough rubber mat that you ‘d put in your pickup. The Velcro for the belt does its job perfectly. The loop joining the bag and belt is big and solid, and the hook mechanism to hold the three 10 lb sand sacks is more than adequate. Nothing is falling out of this.”

This review also highlights the age versatility of the product: “Works well for a wide age range. Easy to use and durable. Easy to adjust weight. Easy to transport with one hand. Great product.”

I use it every week in my training and I can honestly say that it’s one of the things that’s allowed me to see the most improvements in my sprinting the fastest. For people like me that train alone most of the time, it’s the perfect accessory because you can use it all by yourself”.
