Mine is a "Outdoor Products" brand my wife bought at Target. I hate to ride without it because it is so easy to get a quick sip. When you ride with Dreth or Hollywood, there's no time to stop, take off your helmet, gloves, etc to open up a cooler or otherwise.
It did get a small leak during the Rodman cleanup, so I tossed it in the woods.
J/K. Actually, I sent it back under warranty and they sent me back a replacement in 4 days!! Good customer service.
