Osprey Duro 1.5 Unisex Running Hydration Pack with 2x 250ml Hydraulics™ Soft Flasks - Phoenix Red (M/L)

Product Information

Even if you never experience a leak, you’ll at least experience water sloshing more in a bladder at some point. The more you drink, the more space the water has to slosh. The sloshing could throw off your center of gravity and can be pretty loud! Smaller bottles up front shrink as they empty, avoiding this issue. Some vests out there have thoughtful tapered bladders, like the one found on the Nathan Pinnacle 12L. This design reduces the sloshing, but the other cons of using a bladder remain.

Designed by and for the fastest trail runners in the world, this vest has the fit and features to race fast Around 9,000 miles of combined running and hiking miles inform his approach to gear testing — from hikes of the CDT, PCT, Long Trail, and other self-made routes, to runs across the Grand Canyon, trail races, and obscure lines drawn on a map up or down the side of a mountain. Trey firmly believes that a piece of gear should facilitate experiences rather than discourage folks from getting out the door. Keep it simple, keep it functional, and keep it fun! Some running companies understand that unisex just doesn’t cut it for everyone. Often women’s running vests are designed with the assumptions that women generally have shorter torsos, will have different places prone to chafing, require differently tapered vest straps for different chest sizes, and may want an alternative bottle design. We do wish that the light thread also illuminated a bit on the front of the vest, as it is also important to be noticed by oncoming traffic — but bright reflective strips on the shoulder straps provide adequate visibility. Trekking pole attachments:If you like running with poles, it’s great to have a way to stash them if you get tired of using them, or get to a section of trail you don’t need them.The Nathan Pinnacle 12L has the best bladder design and hydration system of the running vests we tested. It ships with a 1.5L Hydrapak insulated bladder, insulated to help keep water cold on the hottest summer days. The shape of the actual bladder is tapered in the middle, creating an hourglass shape, which we found helped with the sloshing problem inherent with many running vest bladders.

What we liked: Light, vents among the best of any vest, intuitive to use, made with recycled silver for a more sustainable silver anti-odor treatment, trekking pole attachment If you’re in the mountains, are there any opportunities to fill up water from natural sources? Just make sure to bring a water filter or some way to treat water if so. Sizing It’s important that whatever vest you go with fits well and doesn’t bounce up and down while you run; (photo/Ilana Newman) Performance running vests can look like a lot of different things. But they are generally oriented towards all-day runs, long trail races, ultra marathons, and technical trails. The ideal running vest is not distracting while on a run. If you’re trying on running vests, add some weight to them (water, layers, etc) and run or bounce up and down to mimic running. See if you notice the running vest. If you do, it will probably distract you, or even worse, chafe while on a long run.When thinking about how much water you need, consider if you will have any opportunities to refill. If you’re running a race, how many aid stations are there? How long is the furthest distance between them? It’s not worth bringing too much more water than you need, since that will just weigh you down. However, it’s a fine line to run since water is a necessity while on the move.
