The Cashel® Horn Bag with Water Pail Pocket has the best of two items. It features the Medium Horn Bag, with the added convenience of a pocket specially designed for the Collapsible Water Pail. It's a great all around bag for those long or overnight trail rides!
The Horn Bag with Water Pail Pocket has two pommel straps and two buckled straps securely hold the bag against the saddle, and the horn opening is big enough to fit the larger horn of a roping saddle. It also has the added convenience of camera/cell phone pockets, and an insulated padded pocket and drink carrier.
The Cashel® Collapsible Water Pail is sold separately.
