Review on Opliy Hydration Pack: Lightweight Running Water Backpack with 2L Bladder for Women and Men by Brian Schultz

Note: The photo was taken after wearing the bag for a year. Sorry, the bubble is not shown in the pictures. He will be deleted. I've had this pack for a few months now and usually use it for light bike rides (less than 30 miles) on the trails. I recently took this backpack on a four day 130 mile trip. It survived and the water stayed cool every day. It rained on one of those days and the bag got wet (also inside) but dried out overnight. The bladder is easy to clean and I can put my whole hand in to clean it. The bag is lightweight and adjustable. My only concern is that one of my clips (the one with the whistle) has come loose and I can't reattach it (see picture). I would also like the seller to mention how to clean the bag yourself. I don't know if it can be washed in the washing machine or if it needs spot cleaning. All in all I would buy this bag again.
