    I was recommended by another trail runner to try Ultraspire products. I purchased the Alpha 3.0 and absolutely love it! Very lightweight, pockets are located in all the right places for easy access. I didn’t think I’d like the bottles that they would be too big, but it turns out I do. The bottles held enough water in between aid stations and was easy to get in and out of the pockets. It felt so good to finally not have all the weight on my back. Thank you Ultraspire!

    My third Alpha, each one better than its predecessor. I love the evolution of the sternum strap system. The front pockets of the 3.0 are great for hauling food or gear if you prefer a reservoir. That said, the bottles are shaped well and utilize a pliable plastic that seems to be rugged. I may ultimately switch to the bottles full time, until then the reservoir pocket is a nice upgrade. Fantastic craftsmanship and utilitarian design make Ultraspire my go-to hydration gear.
