Created in collaboration with our trail running athletes, Flight Series™ takes you longer, stronger. The name says it all: the Weightless Tank Top is so light and stretchy, you'll forget you've got it on. But its featherweight construction isn't at the expense of functionality. Small perforations over key heat zones will help you cool off and the quick-drying FlashDry™ fabric will wick away sweat.

• Lightweight, four-way-stretch woven fabric for comfort and mobility
• Perforated in key heat zones for breathability
• Moisture-wicking FlashDry™ helps keep you cool and dry
• Reflective logo graphic on chest and back for enhanced visibility
