Vest is so light. Love the bottles in front.


  • Light and hold ample gear.


  • Small sizing, built for long torso.

Vest is so light, it has no structure. Structure comes from the gear inside, and when not full the pack tightens down nicely to re-size. Love the bottles in front. 

If you need a super lightweight, full of features vest, this is a great one. Watch the sizing—it runs small and long.

The vest is very light, holds a lot of food, water and essentials, moves with you on the trail like a piece of clothing, much nicer than carrying a day pack.


  • Very light
  • Holds a lot of gear
  • Extremely comfortable


  • Unclear yet on how well it holds up to really tough use on the trail
  • Pretty expensive, but if it is resilient to wear then a great investment

I got this pack 8/2013 after doing a lot of research and talking with lots of people with different vests and packs. I made the right choice because the vest is very light, holds a lot of food, water and essentials, moves with you on the trail like a piece of clothing, much nicer than carrying a day pack.  

I chose the M/L size for my 5' 11" ht. , 150 lb, 38" chest frame which affords expansion room for full loading.

For a recent Half Dome trip took 5L H2O, 8 energy bars, 6 GU packs, bag of trail mix, all 10 essentials, MSR water filter. The hidden pockets for extra bottles are a real help for long dry trips. The large inner compartment will easily hold a 3 L bladder and there is a port for the tube.

Professional Runner Peter Bakwin was the catalyst for the design of the Ultimate Directions PB Adventure Vest. After years of creating his own packs, Peter teamed up with Ultimate Direction to create the high-capacity, bottles-up-front running pack he wanted. Like many runners, Peter found that water bottles were a much more elegant solution to hydration bladders, which tend to slosh around and make it hard to refill on-the-fly. As a result, the Adventure Vest touts a bottle holster on each shoulder strap, which locates your hydration where it's easy to grab and quick to refill. Behind these holsters lies a harness made of stronger-than-steel Cuben fiber (found in America's Cup yacht sails), and behind that, a stretchy storage compartment comprised of Power Mesh. Because of the direct integration of the eight-liter mesh compartment and the carrying harness, the PB has a seamless feeling that you'll swear is an extension of your own body. And thanks to the main compartment's unique one-piece pull cord, the compartment instantly expands or compresses so your load never wobbles. Bryce Thatcher founded Ultimate Direction and he began hand-sewing hydration packs in 1986. Since that time, Ultimate Direction's lineup has expanded dramatically and now includes signature pieces born of collaborations with professional athletes. Compared to other minimalist hydration systems like the AK Race Vest or the SJ Ultra Vest, the PB Adventure Vest offers the most expansive storage and safety features not offered by the other two signature series vests. Ultra runners will appreciate the versatility of the design, and that same versatility may attract ultralight hikers, climbers, and skiers to adopt this vest as well.
