“Bee Better. / One Purchased = One Donated.”
The mission leads, but a shopper deciding between Bombas and a 6-pack from Target needs the product reason first. "Why are these worth 3x?" is answered below the fold instead of in the hero.
“Pair the mission with product: "The most comfortable socks you'll ever wear — and one is donated for every pair you buy."”
Keeps the unique mission while leading with the rational benefit (comfort) that justifies the premium. Emotion + value working together converts better than mission alone.
