Review on TRIWONDER Hydration Pack Water Backpack 5.5L Outdoors Trail Marathon Running Race Cycling Hiking Hydration Vest by Paul Ajayi

Pro: The water bladder it comes with opens up enough you can put your hand inside it to clean it with a dish cloth. I like that. Seems like good quality materials/construction. I've used it twice so far. If you fill it up with cold water it is like a cool pack when it is hot outside.Con: One of the straps slides over after a while and rubs on my neck, but it isn't chafing. The zipper pocket is too small to fit my phone, but does hold a credit card. I put the phone in an open pocket, so far it hasn't fallen out.
