The UD SJ Ultra Vest is the result of collaboration with Scott Jurek, the world’s most dominant ultra runner. Weighing in at 7.5 ounces (13 with bottles) and offering 9.2 L of storage space, the SJ has the best weight-to-capacity ratio of any hydration pack on the market.
World-renowned ultra-runner Scott Jurek designed the SJ Ultra Vest to be the the ultimate pack for any occasion. Featuring the best volume to weight ratio of any pack ever made, the 7.5 ounce Scott Jurek Ultra Vest can carry a half-day of gels or bars in the easily accessible front pockets, along with a unique expandable or compressible main compartment utilizing Cuben-Fiber, for a total capacity of an amazing 9.2 liters. Options to carry trekking poles and an ice axe complete the package.

MATERIALS & DESIGN
Cuben Fiber: Used for the sails of America's Cup racing yachts, this non-woven fabric is 15 times stronger than steel and 40% stronger than Aramid fibers, and is extremely resistant to moisture, UV, and chemicals
Hex Mesh: The structure of the vest is totally breathable, while also being extremely strong, lightweight, and will not absorb moisture.
Power Mesh: All pockets and super stretchy, so small loads won't bounce and the vest expands as you need it to.
