I call it the kitchen sink because it has almost everything. The 70-ounce bladder with full-length plastic handle slides oh-so easily into the wide-mouth insulated compartment. The drink tube is insulated, too, which is great for winter riding. The waist belt not only holds the pack in place but also includes easy-access wing pockets. The chest strap has a built-in rescue whistle. Side loops let you attach your helmet. One gripe: The drink tube’s shut-off knob keeps it from leaking but makes it harder to sip on the fly. $85; mazamadesigns.com
