The Nathan Pinnacle Series Vapor 4L Vest is a lightweight, high-performance running vest built for serious runners who want fast, long, and comfortable outings. Designed to feel like a second skin, it delivers minimalist weight yet smart storage, so you can carry exactly what you need without bulk.

Runners tackling ultra-distance, trail runs, or any long road sessions who want maximum freedom of movement, quick access to essentials, and reliable hydration—without the weight or bounce of heavier packs. It's ideal when you need a compact, professional-grade vest that handles everything from speed workouts to multi-hour endurance efforts.

Model Number: 40260

Details:

• Super-light and breathable: engineered to be about 20% lighter and more breathable than Nathan's earlier Krar and Howe vests, so you stay cooler and move more freely on long runs.
• Thoughtful pocket layout: two water-resistant chest pockets, extra side pockets, new kangaroo pockets, plus a vertical pocket for larger items—everything has a place and is easy to reach, even on the move.
• Better fit and moisture control: the vest's new shape sits longer in the back and uses tapered back panels to wick moisture away, helping to keep sweat from building up in high-heat zones.
• True hydration solution: includes two 591 ml Hydrapak soft flasks with stabilizing ExoSpine and long hose and mouthpiece for convenient sipping without slowing down.

Material:

• 85% polyester, 4% spandex, 8% nylon, 2% rubber
