    This product is for…

    Runners and fastpackers tackling multi-day or 200-mile-scale efforts, with or without crew support. Also suits those who need easy on-the-go access to gear and nutrition without stopping.

    Worth noting…

    Notes are uniformly positive with no reported caveats on fit, sizing, or durability. One host used it during beta testing, so the final production version may differ slightly.
