Osprey Dyna 1.5 Women’s Running and Hiking Hydration Vest Review

As I started increasing my mileage, I quickly realized that I needed a higher capacity hydration solution for my long runs. I’m a slow runner, so a 12 mile run takes me a good chunk of time. The length of my runs combined with the  lack of shade on some of my routes meant that I needed to be able to carry a lot of water on my long run days. After lots of research, I finally landed on the Osprey Dyna 1.5 Women’s Hydration Vest.

The hydration vest features a 1.5 liter reservoir with a QuickConnect hose. The hose has an easy to use bite valve that you can lock if you’d like to (I never do.)  It can be threaded over your right or left shoulder depending on your preference.

It has two chest straps and side straps to create a great custom fit. I am an average sized woman with an above average chest and I’ve been able to get a comfortable enough fit that I barely feel the pack pack on my runs. The chest strap has a magnet clip that helps keep your hose in place.
While the water capacity and adjustability are great, I would be remiss if I didn’t mention that it had pockets for literally everything you could need on your long runs. There’s enough storage for sunglasses, sunscreen, Honey Stinger gels, snacks, extra socks, a phone (my iPhone 12 Pro fits perfectly) and a packable jacket.

I’ve increased the water capacity of my vest by using a Hydrapak UltraFlask in one of the front pockets. I typically use the flask to carry Nuun Sport on my runs while filing the main reservoir with ice cold water.

My only issue with the vest is that it doesn’t have the most inclusive sizing. The sizes max out at 41″ in chest circumference, which I’m sure would exclude a lot of runners in larger bodies.
Overall, it is a really well-made pack made with high quality materials. Osprey backs all their products with a lifetime warranty. They will make repairs to your product no matter when you purchased it. In a world where everything is disposable, a company will make repairs on a twenty-year old product is remarkable.

The Osprey Dyna 1.5 hydration vest currently retails at $90.

Don’t need to carry a lot of water on your runs?
