Pinnacle Pro 6L Hydration Vest

Built for long efforts on technical terrain, the Pinnacle Pro 6L is our top pick for runners who need real carrying capacity without sacrificing fit. Nathan's Quick-Fit micro-adjustment system lets you dial in a locked, bounce-free feel on the move. Two included 20oz soft flasks and a 2L bladder-compatible back pocket mean you can hydrate your way, whatever the distance.

• 6L total storage across front, side pass-through, and zippered back pockets — enough room for a full-day effort without overpacking
• Quick-Fit micro-adjustment system with sternum slider cords lets you fine-tune fit mid-run, no stopping required
• Double-layer air mesh interior and quick-drying fabric keep airflow moving — critical when you're grinding through Southern summer heat
• Ships with two 20oz Nathan x Hydrapak soft flasks with extended straws; back bladder compartment fits up to a 2L reservoir if you need more
• Reflective accents across the vest improve visibility during predawn or post-sunset runs without adding bulk
