ULTIMATE DIRECTIONA(R) JUREK FKT VEST :: Whether you're an Ultra-Marathoner or just like to push your limits on the trail, you've gotta check out the latest addition to the best-selling SJ Ultra Vest series, the Ultimate Direction Jurek FKT Vest. Designed by Champion Ultra-Marathoner Scott Jurek, this vest's technically advanced design and features make it even more comfortable and performance driven than its predecessors. You'll stay well-hydrated without hassle thanks to the new FlexForm(TM) bottles and a reservoir hose that can go anywhere you like it - over or under the shoulder, on your left or on your right. To ensure all your needs are covered, this amazing vest also includes trekking pole holders on the front for easy access and an emergency whistle. Plus, despite its large stow capacity and better storage accessibility, the Jurek FKT won't feel too bulky, thanks to the main compartment's super compressive bungee system.
