Columbia Big & Tall PFG Super Slack Tecas Sport Shirt

Product Insights & Style Tips

The Columbia Big & Tall PFG Super Slack Tecas Sport Shirt balances easygoing outdoor energy with Columbia’s technical DNA. Lightweight and airy, the 100% polyester fabric is intentionally built for all-day wear—whether you’re deep in the city or by the water—with a clever, next-to-skin feel that stays cool even when the heat ramps up. Sun-baked afternoons don’t stand a chance: the shirt’s tightly woven Omni-Shade™ UPF 40 fabric ensures subtle yet powerful defense against UVA and UVB rays, and moisture disappears fast, thanks to Columbia’s signature Omni-Wick™ technology. The experience is breezy, simple, and unfussy—exactly what you want from a summer sport shirt that looks as good as it performs.

Cut with a relaxed, slightly generous silhouette, the Super Slack Tecas shirt layers easily over a tank or tee without clinging, and the vented back amps up the airflow when the weather’s at its most stubborn. Short sleeves and a modified shirttail hem make it equally at home worn untucked or French-tucked, while the chest pocket and utility loop signal that thoughtful carry—like sunglasses or pliers—can stay close by. There’s even a low-key sunglasses cleaning patch built in, so every detail considers a day that doesn’t go to plan. It’s one of those rare shirts that transitions with ease from a midday fishing trip to a late urban happy hour—cool, competent, and quietly technical without shouting about it.
