Built for endurance racing and long days on the trail, the Nathan VaporCloud 11L running vest comes equipped with a 2L hydration system, expandable storage, and convenient organizational features.

The vest hugs your body to ensure a movement-mirroring fit and a bounce-free carry. Dual sliding sternum straps let you dial in fit without getting in the way or causing undue pressure. The ventilated harness cuts down on rubs and hot spots while helping to keep you cool. Soft, breathable, wicking fabrics provide next-to-skin comfort and keep you from chafing. An integrated stabilization system helps to keep contents stabilized and compressed, enhancing balance in the process.

A 2L hydration system is included and fits securely in a dedicated, insulated sleeve. The drinking tube can be run over either shoulder and secures conveniently out of the way thanks to strategically-placed straps. The integrated bite valve provides a steady drink-flow while maintaining a leak-proof design. Integrated over-the-shoulder load lifters minimize "sloshing" by pulling fluid contents closer as the water level decreases.

A large rear main compartment has a zippered closure to keep contents secure. Large zippered lateral pockets expand capacity significantly. Additional pocketing is incorporated into the front of the harness so you can quickly put hands on anything you might need without breaking stride. There are two easy-access front bottle pockets (fit up to 22 oz; bottles not included), a gel stash pocket, and a water-resistant pocket that’s perfect for electrolytes or other pills. A rear bungee attachment system lets you lash layers or gear externally. Other features include trekking pole attachment clips, reflective trim, and a removable safety whistle.

The Nathan VaporCloud 11L running vest has is available in two sizes. The Small/Medium best fits chest sizes measuring 33”-39” and the Large/Xlarge fits from 37”-44”.
