The Ultimate Direction FASTPACK 40 is a favourite for moving fast and light in the backcountry or on the trail.

This lightweight Fastpack 40 has an optimal weight-to-capacity ratio for longer adventures over rugged terrain so you can move fast in the backcountry. True to our roots, it uniquely fits like a vest with water bottles up front, but distributes weight like a pack. We gave it an upgrade with Infiknit™ and FastFlow technology to increase the backpanel’s breathability and moisture wicking. This do-it-all pack also has plenty of dedicated external storage, a roll-top opening and a full-side external zipper for easy to anything inside.

  • Large front and side storage for water bottles, phone, maps, glasses or food
  • Unique zip-down design for quick, total access to gear in main compartment
  • Roll-top closure expands or compresses to secure varying capacities
  • MonoRip Mesh material is durable yet extremely breathable
  • Sliding rail sternum straps for an adjustable fit
  • Height-adjustable and removable T-hook waist belt distributes heavier loads
  • Easy access pocket with key fob
  • Water bottles not included

About Ultimate Direction

It all began when UD founder, Bryce Thatcher, solved his hydration problems by taking matters into his own hands-crafting his first hydration pack on his mother’s sewing machine.

Our mission is to provide the ultimate in high performance hydration for everyday athletes. We reengineer, reinvent, and redefine high performance hydration for everyday athletes.

In 1985 Ultimate Direction invented the entire category of hydration packs. We created the first waist pack for carrying bottles, a few years later made the first pack/strap to carry a water bottle in your hand, and have made many other innovations that define what a hydration pack is today.

30 years later we remain a market leader, having created and popularised the “vest” concept for carrying water. We introduced the very first women’s-specific line of hydration packs and have brought the classics of the past into the technical future with award-winning gear such as our Fastpack and Ultra Jacket.

Our products are designed by athletes for athletes, and the Jenny Collection was designed by women for women. Some of the best runners in the world thought long and hard about what works the best, and the result is absolutely great gear.
