Phase-change material pockets arranged in giraffe-spot patterns that stay cool for 2+ hours. Yoyo-pull activation circulates cooling throughout the garment using evaporative cooling inspired by how frogs regulate temperature through their skin.
Your child runs around the playground on a 95°F day, staying comfortable and protected in their CoolSpots rash guard while other kids are overheating — you pull the activation cord and see the spot patterns subtly change color indicating active cooling, knowing they'll stay cool for hours without any batteries or chemicals touching their skin.
