    LOVE

    I’m petite and this XS top fits perfectly! I haven’t found another top that I love the fit as much as this one. I’m sad that it seems to be almost completely out of stock. Please keep it in your line up!

    It’s Special

    The Flowstate Core Tank (No. 7231)

    There’s a court in the South of France, hidden behind ivy-draped walls, where the clatter of paddles echoes off ancient stone like a secret whispered through time. The players—lean, sun-kissed, defiant—move with a grace that belies the sweat beading on their brows. They wear no ordinary garb. No, they’ve chosen something elemental, something that breathes with them: the Stack Athletics Flowstate Core Tank.

    Crafted from a ventilated blend—90% polyester, 10% elastane—this isn’t just a shirt; it’s a second skin for the modern warrior. Moisture-wicking, quick-drying, it laughs in the face of exertion, keeping you cool as the Mediterranean breeze while you lunge for that impossible shot. The high neckline rises like a subtle challenge, a nod to the elegance of purpose, while the solid hues—deep midnight, crisp fog, bold cobalt—pair effortlessly with whatever the day demands.

    I wore mine last summer, chasing a rogue pickleball across a dusty court in Provence. The sun blazed, the air thickened, yet the tank held its own—soft as a whisper, unyielding as resolve. Later, over a glass of rosé at a café table, it looked as sharp as it felt, drawing a knowing nod from a passing local who mistook me for a pro. Maybe I was, for a moment.

    Fits true to size, they say. Machine wash cold, tumble dry low—practicality masquerading as simplicity. But this is no mere athletic wear. This is a companion for those who live loud, who make noise, who turn a game…
