When you travel, luggage space is at a premium, so pack versatile pieces. We love Columbia's Global Adventure Zero Polo, which looks sharp in the airport or on a fishing charter and features some cutting edge technology to keep you comfortable. The stretchy cotton/poly blend fabric sports a 50 UPF rating to combat the strongest sunlight, stretches nicely for for swinging a golf club, hiking (or even a run), and doesn't wrinkle even after being crammed into your duffel.
It's also imbued with Columbia's Omni Freeze technology, which uses your own perspiration to help cool you down. Thousands of millimeter-wide polymer circles are imbedded into the fabric. Get them wet and they expand to absorb the moisture, a mechanical process that also pulls in a little of your body's heat.
The company claims it can reduce the temperature of the fabric by as much as 10 degrees. We agree that it works – you can feel a cool tingle when the fabric dampens. In cooler weather? No problem, the plush fabric insulates better than pure cotton polos. [$55; columbia.com]
