A Review of My Osprey Dyna 1.5 Hydration Vest

August 18, 2022

HI! I’m Molly.

Here to encourage you on your own bold pursuit of intentional living as I live out my own. I’m passionate about running, spending time doing what I love and cheering others on to approach running with joy.

One of my most frequently asked questions is about my hydration vest, so I wanted to put together a short review of my Osprey Dyna 1.5 hydration vest in case you’re looking for a hydration pack for training.

My husband and I started trail running when we lived in Austin, and prior to that, I never ran with hydration. I hate holding anything while I run, so I never used water bottles and I would either find routes with water fountains along the way or would circle back home to get water. Enter trail running. Neither of those two things were possible anymore, yet I still hated holding something, so I knew I needed to find a hydration vest. 

We jumped into trail running pretty quickly, so I didn’t do much research on packs. We went to REI the night before going on a long trail run and I tried on all the vests there. The Osprey one was by far my favorite and luckily, I’ve loved it since then! 

What I Love About the Osprey Dyna 1.5

Here is what I love about it:

  • There’s no bounce when there’s water in it
  • It stays on my shoulders (check to see how much space there is when you lift up on your pack - you don’t want a lot of room in between the pack and your shoulders)
  • It has front pockets, which makes it easy to store fuel for easy access while running, as well as a small back pocket
  • Easy to fill, remove and clean bladder
  • Magnetic clip for the straw
  • Affordable 

I will say, this pack is perfect for my training runs now, however, I don’t know if it will hold everything I need for the ultramarathon I'm running in November. The pockets in the front are big enough to hold 3-4 gels/energy bloks on each side (which is more than enough for a marathon training run), but they wouldn’t be big enough for all the food I’ll need during the ultra. If you're running a marathon, you won't want the hydration pack during the actual race, so I think this would be perfect to use for training during that cycle!

The bladder holds 1.5 liters – hence its name – which for me, lasts anywhere from 11-13 miles depending on how much I drink. I never ran on trails longer than that and now, I'll make my route run past my car at that point and refill it for the rest of my runs if need be.

You can see videos of me wearing it on my Instagram and TikTok.
