GoCJ Arizona Ice Large Industrial Ice Packs, Two-Pack 12 x 9 — -8°C (18°F) Phase-Change, Deep-Groove Cooling

GoCJ Arizona Ice Large Industrial Ice Packs are heavy-duty reusable cold packs that replace up to ten pounds of loose ice and hold a steady -8°C (18°F) for extended cooling in large coolers and transport.

These AZ Ice packs are engineered for high-capacity cooling where ordinary lunchbox packs fail: large surface area, deep grooves to conform around gear, and a phase-change formula that freezes colder than water ice. Each two-pack arrives pre-filled with a proprietary powder; you simply add water once, freeze, and reuse for seasons. The 12" x 9" size provides industrial-style performance for fishing, camping, deliveries, and any situation that needs sustained cold without melting puddles.

How do these large ice packs perform compared with loose ice?

AZ Ice is designed to replace roughly 10 pounds of bagged ice while keeping contents dry and at a consistent cold temperature. Their phase-change formula freezes lower than water ice, so they hold cooling power longer and produce less mess.

• Two 4-lb packs equal about 10 lbs of loose ice in cooling capacity.
• Maintains -8°C (18°F) for extended periods—colder than melting ice.
• Rigid shell eliminates water runoff and soggy contents.
• Deep grooves improve contact area and fit inside coolers.

How do I prepare and use the GoCJ Arizona Ice packs?

Setup is a one-time, tool-free step: fill with tap water using the integrated fill port, seal with the child-lock cap, and freeze flat. After the initial fill and freeze you can reuse the packs indefinitely—no measurement, funnel, or additives are required.

• Arrives pre-filled with powder; consumer adds water one time only.
• Child-lock cap secures contents and prevents accidental opening.
• Freeze flat to maximize contact with cooler contents for best performance.
• Durable outer shell resists punctures and repeated use.

Will these fit in my cooler, and what about shape and handling?

These are large-format packs intended for big coolers, crates, and transport boxes—not small lunch containers. The 12" x 9" footprint and deep ridges are optimized for close contact with bottles, fish, or cartons while keeping overall thickness compact for efficient stacking.

• 12" x 9" dimensions—measure your cooler before buying to ensure fit.
• Deepest grooves on the market for better surface contact and flexibility around contents.
• Compact thickness allows stacking and placement next to bulky items.
• Two-pack layout gives balanced cooling across larger loads.

Are these durable and safe for transport or outdoor use?

GoCJ builds the Arizona Ice packs for rugged use: a thick, tear-resistant shell and secure cap mean they survive rough handling. The internal formula is non-toxic and uses phase-change materials rather than loose gel beads, minimizing leakage risk when the pack is intact.

• Indestructible-style construction resists punctures and drops.
• Non-toxic phase-change formula reduces hazard concerns if damaged.
• Designed for repeated freeze-thaw cycles without deterioration.
• Ideal for fishing, delivery services, road trips, and camping.
