Review on 🎒 Ultraspire Zygos 2.0 Hydration Pack with 2L BPA & PVC Free Reservoir and Mag-Clip by Mike Devine

I bought the Ultraspire Zygos 2.0 to replace my aging Camelbak Ultra Pro. I've only run about 75 miles with my backpack so far. The Zygos 2.0 fits great (I'm 5ft 8in, average backpack size is 155lbs) and doesn't bounce or chafe. Front and side pockets are large and easily accessible. Bottles slide easily in and out of the front mounts. Plenty of storage space for long runs and ultramarathons with long distances between help points. The zippers take a little getting used to, but work well. The only thing that didn't convince me was the two liter tank that comes with the kit. It works well, but I like the camelbak bite valve a lot more. It also seems to be a bit hotter than the Ultrapro. The Zygos 2.0 appears to be very well built and should last a very long time. Great package for your money.
