The bonded neck opening on The North Face Summit High Trail Tank Top means zero chafing from stitched seams, while FlashDry-Pro recycled polyester actively pulls moisture off your skin and disperses it so fast you'll wonder how such a lightweight piece can work this hard. The split hem and darted seams give you unrestricted mobility, and at just 99 g/m² fabric weight, this tank feels like wearing almost nothing while delivering serious performance.
