A stylish, perfect size bag for a really great price point. I've filled this thing with gummy snacks and energy chews for adventure rides, fruit, cheese, and a sandwich for long hauls, a big ol' iced coffee for my morning commute, and even a tall boy for the pregame ride to the pregame. Love the way this bag looks on my bike and love how it holds a whole lot without getting in the way.
I picked up a stem bag from Wonder a while back and rarely leave home without it. Sometimes it's the only bag on my bike, and at different times I've used it to carry things ranging from a large chain lock, a small handful of tools (flat fix kit+), a plethora of snacks, even small rain jackets. These bags can fit more than you'd think in them, but are never overkill, and will fit on nearly any bike. Stem bags are also great solutions to bikes that can't take a traditional bottle cage, like really small, or really old bikes, or full-suspension mountain bikes. Keep one on your bike at all times, just in case, or throw two on to round out your storage capacity for a tour or bikepacking trip.
