Absolutely not! We’ve built in two tube holders on the right and left side of the shoulder straps to hold the tube in place. Depending on your weight, and gender, there are different ways to secure the hose, either by running it from the left side holder to the right, or running through a single side and then securing the hose beneath the chest strap. Experiment with a few different ways and see what works best. Overall point, YES, the tube can be easily secured in multiple ways.
