WATERFLY Running Belt Fanny Pack: Runner Marathon Jogging Waist Pack Sport Workout Exercise Fitness Phone Holder Belt for Men…

Across the reviewers we read, this WATERFLY belt is the second-best-documented pick here. The running-belt guide at nytimes.com (high trust) calls it versatile and, for the price, reasonably durable, noting a staffer kept one in good shape for about two years. Runner's World (runnersworld.com, verified) describes it as small but mighty, with stretchy compartments that swallow a phone, gels, and bars; we treat that outlet's subjective praise as supporting evidence given its commerce-media parent, but its description of the carry capacity is useful.

Community sentiment reinforces the trail-running angle: across r/Marathon_Training, r/PHRunners, r/XXRunning, and r/beginnerrunning (all medium trust), reviewers repeatedly describe it as snug, comfortable even worn against the skin, and stable enough to carry hydration when positioned in the small of the back. The recurring caveat is the same one that follows most belts, get the sizing right or it can shift.

For runners who want a slim, sweat-resistant belt that can stretch to hold more than a phone, the trust-weighted consensus is positive, with the main reservations being long-term durability at the price point and fit sensitivity.
