SKLZ "Speedsac" – the flexible weight sled
The SKLZ "Speedsac" is a robust, hard-wearing weight bag and is perfectly suitable for sprint training with additional weight. It can be used on almost all types of surface (except for tartan tracks). With the adjustable harness it is quick and easy to attach to your hips, so that training can start straight away. With the "Speedsac", you also receive 3 sacks – each one can be filled with different quantities of sand up to a maximum of 4.5 kg. As a result, the weight sled can be individually adjusted to your fitness level, training goal and age. Particularly practical: the sandbags have handles, so that the small weight bags can also be used in functional training of the upper or lower body. Product information:

- Weight of the "Speedsac": approx. 1.9 kg
- Size of the weight bags: 33x19 cm

- Incl. 3 fillable sandbags (for approx. 4.5 kg of sand each)
More than just a sprint trainer
The SKLZ "Speedsac" functions in a similar way to the metal sled, but it is more flexible and easier to use. Due to its size and smaller weights it can fit into every bag. In addition you don't have to drag heavy weights to training because you can simply fill up the sandbags on site with sand from a landing pit. Our tip for running training: the weight of the SKLZ "Speedsac" should not exceed 5% of the user's bodyweight.
