Liberty Bottleworks Topo Water Bottle with Navi-Cap

This screw-top bottle will keep you hydrated and on-course. The single-wall, 24-ounce aluminum bottle comes with a Brunton compass attached to the lid (and both the bottle and compass are made in the U.S.). The bottles are emblazoned with topo maps (courtesy of DeLorme); take your pick of 11 locations. Caution: Pay attention when attaching the lid; you need to line up the tabs and twist firmly for a leakproof seal.

$33; 6.2 oz.
