he Phase 23 temperature pack is a shipping add-on designed to help stabilize temperatures during transit for live animals, plants, and sensitive bioactive supplies.
Phase 23 packs activate at 23°C / 73°F, helping buffer against temperature fluctuations rather than aggressively heating or cooling. This makes them ideal for mild temperature changes, spring and fall shipping, or situations where added stability is recommended without extreme intervention.
This add-on is used at our discretion based on your shipping route, weather conditions, and carrier delays to provide the safest possible transit environment.
