Columbia upgraded the Half Track with Backdraft™, their latest back-panel ventilation technology featuring directional foam conduits that direct hot air out and cooler air in. Slip your laptop into the zip-closed computer compartment, which is reinforced with an EVA foam shock absorber—because we know that you can’t always set your pack down as delicately as you’d like. Beefy buckled straps on the front hold a skateboard as easily as a jacket, and the rugged number-ten YKK zipper on the main compartment takes wear and tear in stride. An electronics pocket is lined with soft tricot to protect lenses and displays. Hauling a heavy load? The hip belt happily takes the weight off your shoulders—but it’s also removable so it’ll never be a nuisance. Reflective accents keep you visible during late-night capers.
