Pinnacle 4L Hydration Race Vest

Built for ultramarathon race day and fast-packing pushes, the Pinnacle 4L is our top pick when every gram and every minute matters. Body-mapped construction keeps the load centered and stable, so bounce and hot spots don't become problems at mile 40. Four liters of smart storage handles nutrition, emergency layers, and mandatory gear without turning you into a pack mule.

• 4-liter total capacity handles nutrition, emergency layers, and mandatory race gear through your longest efforts without excess bulk
• Body-mapped construction distributes load close to your center of gravity — less bounce, fewer hot spots, and no chafe deep into a run
• Unisex fit in XS through L accommodates a wide range of builds while maintaining a locked, stable feel that won't shift mid-race
• Built for ultramarathons and fast-packing where weight savings, quick access, and fit stability all matter when the clock is running
• Available in Black/Finish Lime and Estate Blue/Ribbon Red — both give you trail visibility without screaming high-vis from a mile away
