This iconic (fuschia), female-specific featherweight hydration vest has been upgraded for even more comfort. Lightweight fabrication, female-friendly design, and a repositioned bladder tube exit maximizes comfort, while eliminating skin contact.

Long periods of exertion demand hydration, and comfortable ways of carrying it. The Intensity meets the challenges encountered specifically by female distance runners – uncomfortable shoulder straps, too-short vest length – and offers a vest that is so comfortable you’ll swear it’s an extension of your shirt.

About Hydration Systems

Letting yourself get dehydrated is the quickest way to compromise your performance and ruin your fun. A hydration system lets you carry a good amount (usually 2 or 3 litres) of water without interfering with your hands and with a convenient valve to drink from whenever you like. During intensive exercise, you'll need to drink around 1 litre of water every hour which means sipping little and often - much easier if you don't have to stop what you're doing and locate a bottle. Adding an energy drink to the water makes the process even more effective and can enhance performance. Make sure you choose a cleaning kit to go with your system or you'll be buying a new reservoir regularly! Different systems combine varying amounts of hydration capacity with a wide variety of cargo options, meaning you can carry everything from an energy bar to all the gear you need for a full day out.

About the Nathan brand

Most companies products are born in the boardroom, often mere clones of successful products conceived by others. At Nathan, the labs are the terrain we constant strive to conquer. Product research involves scaling the Tetons, crossing the Grand Canyon or clinging to a sub-6 minute pace 20 miles into a marathon – because what needs to be improved becomes clear only under extreme conditions.
