I have a bit of a bag problem. I really like sling bags and use them all the time. They are lightweight and unobtrusive; perfect for carrying compact items and extra clothing. In recent years, cycling and adjacent bag makers have put their own spins on the classic sling “musette” bag design to enhance functionality with stabilizing straps, extra pockets, and more. Since they are usually relatively affordable I’ll pick them up when I’m traveling as functional souvenirs.
While not in any way a comprehensive list (that would be difficult as there are LOTS of options out there), this roundup features bags I’ve acquired in person from Albion Cycling, Outer Shell, Swift Industries/Camp and Go Slow, Tangente Atelier, Team Dream, and Tunitas Creative.
