Q: Can the waist strap adjust to fit different body sizes?

A: Yes! The belt is approximately 48 cm in length and is adjustable to comfortably fit a variety of waist sizes, ensuring a snug and bounce-free fit during all types of physical activity.

Q: Is this bag suitable for activities other than running?

A: Absolutely. While it's optimized for running and marathon training, this waist bag is equally well-suited for hiking, cycling, gym workouts, fitness walks, and any outdoor adventure where keeping your hands free is a priority.
