The next generation of hydration systems... designed by athletes for athletes.
"The Race Vest is super light and minimal... but easily carries everything I need." -- Anton Krupicka
Designed by Anton Krupicka, the AK Race Vest brings minimalism to the world of hydration. Weighing in at a feathery 6 ounces, the AK Race Vest is the world's lightest hydration pack. With all the features you need and none you don't, the AK Race Vest offers twin bottle pockets, a main compartment for gear or a reservoir, and several smaller pockets easily accessed on the go. The Power Net Mesh holds small items securely while expanding out to a full 4 liter capacity.
The Signature Series was designed by three of the most successful, most well-known ultra runners in the world. Using power mesh for zero bounce and state-of-the art cuben fiber for its unsurpassed strength to weight ratio, our Signature Series vests integrate load carrying, performance, and comfort into one unified system. With water bottle pockets in the front of the vest for quick and easy access, the Signature Series represents the next generation of ultra running hydration packs for runners.
