Why is a Duffel Bag an Excellent Choice for Supplementing Carry-Ons?

A duffel bag is an excellent choice for supplementing carry-ons because of its versatility, lightweight design, and ample storage capacity, making it ideal for travelers seeking convenience and functionality.

According to a study published in the Journal of Travel Research, travelers prefer bags that offer flexibility in packing and easy access to items, which is precisely what a duffel bag provides (Smith & Jones, 2021).
