When you need water and race-day essentials without the bulk, the Marathon Pak 2.0 is our go-to vest for long-distance runners. Its low-profile, vest-style fit keeps weight centered and minimizes bounce, so your stride stays clean mile after mile.

• One-size unisex fit works across a wide range of body types — no sizing guesswork on race day
• Built for marathon racing and long training runs where carrying water and essentials isn't optional
