It's easy to become dehydrated on a motorcycle, and dangerous in how it impairs your judgment, particularly if you are out for an all day ride or touring. Handling a water bottle as you are riding down the road is unsafe as well. A dehydration pack is a nice accessory to include in your arsenal of riding equipment. I just scored an exceptional buy on a good quality hydration pack through Cabela's. Here's the link if you are interested:

information to those who may be interested. I hope this is helpful and stay hydrated out there!
