Collection: Upass 3oz Kits | The Complete Lineup

Every configuration of the official Upass 3oz kit in one place. The formula never changes: lab-tested synthetic urine with urea, creatinine, balanced pH, and correct specific gravity, plus the temperature strip and heating pad in every box. What changes is how many you get and what comes with them: the single kit for first-timers, the free-shipping 2-pack that most customers settle on, the 3- and 4-packs for the lowest per-kit price, and warmer bundles that add Hot Sacks heat sources for hours of stable temperature.

All kits ship from Safeguard Labs, the original manufacturer, same-day on most orders, sealed with a 2-year shelf life and the batch date printed on the box.
