Nathan Women's Pinnacle Pro 12L

The Nathan Women's Pinnacle Pro 12L is the women's-specific vest with sternum straps designed to avoid chest pressure and Quick Fit adjustment you can dial in mid-stride.

The Women's Pinnacle Pro 12L is Nathan's lightest race-ready vest engineered specifically for women's bodies—delivering 12 liters of organized storage with a compression fit that hugs your torso, not your chest.

Women's Pinnacle Pro 12L

Women's-Specific Design That Fits – The shoulder straps and torso cut follow the natural curves of women's bodies. Sternum slider cords position above and below the bust—never across it—so you avoid that pressure point other vests create. The Quick Fit system on both sides lets you make micro adjustments while running. Your body changes over 50 miles. This vest adapts with it.

The Storage Layout Ultrarunners Asked For – Eight front mesh pockets organize nutrition by the hour—top pockets fit 20oz soft flasks with elastic retention. Two side pass-through pockets mean you can stuff gel wrappers without breaking stride. The oversized back pocket opening lets you grab your rain shell mid-climb. Inside, a separate bladder compartment keeps your 1.6L insulated HydraPak hourglass isolated from gear, so nothing gets soaked when you refill at aid stations.

Breathability Built Into Every Panel – Interior air mesh against your skin creates cooling channels that move heat away during climbs. The quick-dry fabric wicks sweat before it pools against your sports bra. Women testing this vest reported staying noticeably cooler on exposed sections where temperature management determines whether you finish strong or DNF.

What Makes This the Pro Version

Nathan took the standard Pinnacle 12 and upgraded everything. The Pro adds elastic slider sternum cords (replacing rigid straps that dig in), four pole keepers instead of two, that Quick Fit adjustment system for on-the-run micro changes, and includes the insulated 1.6L bladder that keeps water cold for hours while minimizing slosh with its hourglass shape.

Using Nathan Women's Pinnacle Pro 12L

Load the bladder and route the hose through your preferred shoulder exit. Front flask pockets accommodate 20oz soft flasks if you want quick-access electrolytes separate from bladder water. Pack hourly nutrition in the layered front pockets. Use the interior zippered pocket with pill compartment for S-Caps and the key fob for your drop bag keys. Attach poles to any of the four keepers—horizontal for technical terrain, diagonal for flow trails.

Built for women running 50Ks to 100-milers where comfort over distance isn't optional. The 12-liter capacity handles self-supported long training runs and races requiring layers, full hydration, and emergency gear through changing conditions. At just 8oz without the bladder, it delivers exceptional weight-to-capacity ratio without sacrificing the fit women need.
