POC's Column VPD Backpack Vest allows us to carry our essentials in a backpack that also provides optimal back protection during our epic mountain bike adventures. We like that it features a mostly recycled construction and mesh straps for added ventilation, while the adjustable double sternum strap and shoulder straps provide a secure fit. For easy access to our smaller essentials, we store them in two pockets on the chest strap and store our phone securely in the padded phone pocket.
