Collection: Upass 3oz Kits | The Complete Lineup

Every configuration of the official Upass 3 oz kit in one place. The kit never changes: independently lab tested, quality-checked in-house, with the temperature strip and two Hot Sacks air-activated hand warmers 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-pack and 4-pack 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 manufacturer since 2009, sealed with a two-year shelf life and a lot number and expiration date printed next to the UPC. Upass is in stock, and orders placed by 3:00 PM PT Monday to Friday ship the same business day.
