Spry
Inspired by world-class ultra-athlete and our Elite Immortal™, Krissy Moehl, who handholds her hydration, but also wears a racing vest without a bladder to carry foods and other essentials. So, here it is, a minimalist approach to a soft breathable vest.
 |
Surge
Lite weight racing vest with dual side compression and 2L hydration compartment for those who prefer a bladder. Our elite immortal team suggested this for quick and easy access at aid stations. The intent of the pack is to move you through aid stations efficiently. There is an elastic band on the inside to hold bladder from moving about. *Note: Strap Keepers not included. They are for photography purposes only.
 |
Revolution
Ultra Racing Vest inspired by Elite Immortals™ Dana Miller and Jeff Browning. Both ultra-athletes eschew bladders for bottles and appreciate the efficiency of minimalism. Dana prefers a pack that carries bottles. Jeff prefers to hand hold his hydration but also carries a spare. This pack is perfect for both.
 |
Kinetic
With an uncanny kinesthesia* sense, this is the first performance bottle vest backpack! Finally, those who love bottles can return to them wearing a revolutionary vest! With an emphasis on freedom of movement, form follows function, in this power packed race vest. Also featuring Body Rhythm™ harness, this pack is built from the waist up to retain a low center of gravity for balance and control while animating the pack with motion capability that mimics the movement of a human athlete’s hips and shoulders, as opposing forces in motion. This means the pack moves multi-directionally in tandem with the wearer.
 |
Omega
This pack began as a custom pack for Elite Immortal Krrissy Moehl’s return trip to the UTMB at Mont Blanc to defend her record and first place finish. But, many of our immortals saw prototypes of this pack and wanted it too! We thought there must be more runners out there who would feel the same way about this incredibly light weight and surprisingly accommodating, pack. Though a challenge to create a pack that was both light enough to wear for a hundred plus mile race, and large enough to stow all the necessary equipment, this paradox has found itself a home in the Omega. The Omega is a larger version of the Surge pack
 |
Fastpack
A pack for the true voyager; lite weight but roomy enough to carry sleeping gear, extra clothing and everything needed to cover serious topography with ease and efficiency without impeding speed. The concept of “Fastpacking” was born out of the adventures of some early pioneers of trail “running” in the Wind River Range of Wyoming and other beautiful areas that previously required days—and several nights—to see. This hybrid speed “hiking” seemed rather odd at the time, but now has become a regular passion for many a running explorer of fine country!
