This item was the right size, as described. It seems to have hose and bite valve connections that will not leak. At first I was worried the bite valve was defective as no water would go through it. But I just chewed on it for a while and eventually, the valve seal broke and water came through. Overall I’m satisfied with this water reservoir.
Received the item and the zipper was broken, contacted seller and sent pictures but instead of a friendly email i was accused of sending pictures of another item that was used. i just wanted a back pack that was working but i was insulted, stay away from this seller, i guess he doesn't like damaged items being returned.
