A backcountry shower may sound like too much of a luxury to fit in your pack, but the Helio stuffs down to a respectable 5.5" x 8.5" package and weighs a modest 25 ounces. Step on the foot pump to increase the pressure and enjoy the spray nozzle jet (and fairly warm water, too, if you let it sit in the sun all day). And why even worry about packing it – it's an especially welcome relief back at a car base camp after a muddy ride or dank, dusty day of canyoneering. [$100; nemoequipment.com]
