The UNIT 1 Water Bottle is designed to fit perfectly in the TORCH backpack’s water bottle holder.
If using a different bottle, the fit depends on its size. The holder is best suited for:
Capacity: Up to 600 ml.
Maximum diameter: 3 inches (7.6 cm).
Maximum height: 10 inches (25.4 cm).
For the best fit, we recommend using standard-sized bottles within these dimensions.
