UltraLight 5L Hydration Running Vest – Zero-Bounce Trail Pack for Long-Distance (Unisex)
For the lower price this appears to be a nice addition to my hydration vest collection. Comfortable enough with a ton of pockets plus it comes with two squishy bottles which helps add to the value.
This is the first time I have tried a running vest and I'm pleased with my purchase. There are a number of pockets/pouches on both sides of the vest and couple of them large enough to carry my phone (plus I can zipper it close). I had to get use to sucking up water from the flask, which is new for me. I assumed the two flasks included caps for the mouthpiece. Once I contacted customer service and explained my concern the matter was addressed very quickly. Great product and excellent customer service. Vela, thanks.
I own quite a few running/hiking packs and hydration bladders and this is by far my absolute favorite! You can tell there was great attention to detail put into every little feature.
Love this hydration vest for my long runs! Doesnt move around much and has plenty of pockets for all of my things that I carry on longer runs.
This is great to run with. This fits me perfectly. This holds my AirPods and a small key. It has a pouch for hydration packs in it, I have purchased them but havent tried wearing them yet with the vest. Incredibly durable little vest.
Nice little backpack for hiking. It comes with one big pouch and two small ones. Pretty spacious for what it looks like. Very lightweight and has adjustable clips for more comfort! I loved it
UltraLight 5L Hydration Running Vest – Zero-Bounce Trail Pack for Long-Distance (Unisex)
This water pack is the perfect size for running short or long distances. I am able to fit my IPhone Max into the pockets and I am able to tighten the straps to fit my body well. I do recomcomend cycling water through it a few times, I added Dawn just to help with disinfecting and removing the taste of the plastic? It is not heavy even when filled and was a great price.
I love the many pockets, each of them spacious, and the water container itself is large and closes beautifully with how its designed (opening folds and locks with a plastic liner you just have to slide in or out). I love this pack! Material is of quality as well.
