I’m currently deliberating several options for my work commute bag, including a medium crammed tote + clipped-on appendages vs a large duffle/tote vs a duffle/knapsack hybrid.

Free hands are a must, so the factors at play include comfort, style, “professionalism,” and accessibility of contents (I pump while commuting).

One of the factors that I had overlooked was any potential chaffing of these large bags on fabrics. The tote and tote/duffel are made of very smooth fabrics, while the duffle/knapsack has feet that would be against my back when worn as a knapsack. Is the fabric or a snug fit more important when trying to minimize friction?
