UD Signature Series ultra running vests have been designed by three of the most successful, most well-known ultra runners in the world... Anton Krupicka, Scott Jurek and Peter Bakwin. Using power mesh for zero bounce and state-of-the art cuben fiber for its unsurpassed strength to weight ratio, the 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 ultra runners.

Designed by Anton Krupicka, the AK Race Vest brings minimalism to the world of hydration. Even though it weighs in at only 6 ounces (10 with bottles), the UD AK Race Vest still has plenty of capacity for food, clothing, and a phone, so you can use this vest for anything from 10 to 100 miles.

The SJ Ultra Vest is the result of collaboration with Scott Jurek, the world’s most dominant ultra runner. Weighing in at 7.5 ounces (11.5 with bottles) and offering 9.2 L of storage space, the UD SJ Ultra Vest has the best weight-to-capacity ratio of any hydration pack on the market.

Peter Bakwin wanted a pack that could do anything from running to hiking, climbing to skiing. Featuring 12 L of volume and a variety of features, The UD Adventure Vest allows you to stay hydrated and comfortable on any size adventure from quick outings to all-day expeditions.
