    1. Small size for shorter runs easy refills

      I love the size ... fits most of my run packs. The east top fill is the best. UD makes durable gear. Thank goodness! on Aug 2nd 2017

    2. Excellent

      It's a very good and efficient hydration system. Easy to use and not messy. This is a sound investment. It slides easily into the vest and it works great with the UD Marathon Vest. on Jun 5th 2017

    3. 50oz UD reservoir a disappointing purchase

      I am a huge fan of the Ultimate Direction AK 3.0 vest. I am a 167m tall, 60kg female trail runner and run anything from 2 hour to 10 hour trails as well as multi-day stage races. The vest(small) carries everything I need, even in extreme conditions. However, the 50 oz(1,5 l) UD reservoir has two huge drawbacks - the straight closure mechanism is stiff, hard and has sharp corners. No matter how full it is, it digs into my shoulder blades through the thin mesh and makes running very uncomfortable. I have wrapped a buff around the top to cushion it but invariably the buff moves and after a hour or so it is chafing again. Secondly, the tubing is too narrow and trying to get a good drink of water one needs to suck really hard to get a decent flow. Sadly, I have had to resort to a 1,5 litre Camelbak reservoir with a front closure. on May 18th 2017

    4. A practical, easy to clean, no frills bladder!

      This is a great product to add to your UD pack. 50oz is the perfect size to supplement the body bottles up front. I can keep tailwind, nuun, etc in the body bottles and sip on the bladder full of water too. Super versatile, easy to clean, easy to fill, and a great construction! It's even got "Ultimate Direction" printed on it. on Dec 12th 2016

    5. Best reservoir out there!

      I love my UD reservoirs! They are easy to clean and dry; I flip them inside out. I've never had one pop on me, and I use them regularly. Other brands have leaked -- UD never has!
      I love that they come in different sizes for different sized packs and for longer or shorter excursions. The 50 is the one I use most often.
