I Heart Lactic Acid Formula Unisex Hoodie

Most people avoid the burn. You named it, framed it, and put it on a hoodie.

Featuring the chemical formula for lactic acid, this hoodie is your declaration that you know exactly what's happening to your muscles at mile 20 — and you welcome it anyway. Science-nerd energy meets runner stubbornness. The result is a hoodie you'll reach for every single day.

Soft enough for recovery days. Bold enough for everyone else to ask where you got it.
