The Columbia® Headstream is the watch to choose for those who move easily from mountain summit one weekend to mountain stream the next. In addition to its digital altimeter, barometer, and compass, this piece also features a Sail Timer for the water racer, allowing you to focus on where the boat needs to go while the Headstream keeps track of when it needs to get there. The durable PU band resists the wear of multiple dunkings and dryings.
