A high-performance ice jug for camping
Do you have any of these concerns when camping or having a barbecue in summer?
- Ice melting quickly
- Drinks becoming lukewarm
- Opening the cooler over and over
- Buying more ice at the convenience store every time
The ZEN Camps ice jug is a high-performance cooling jug developed to keep ice for long periods.
Its excellent cooling performance from the vacuum-insulated double-wall construction makes it useful in a variety of situations, including camping, sleeping in your car, fishing, and watching sports.
How long does the ice jug keep ice cold?
We filled it completely with ice and conducted a cooling retention test outdoors.
Cooling retention test results (1 gallon)
- After 1 day: 81% ice remaining
- After 2 days: 66% ice remaining
- After 3 days: 59% ice remaining
- After 4 days: 50% ice remaining
The results showed that approximately half of the ice remained even after four days.
Moreover, even the half-gallon size still had ice remaining through the third day.
Even during multi-night camping trips or midsummer outdoor activities, you can reliably keep enough ice for drinks.
※Average temperature: high 30°C / low 19°C
※Results verified in in-house testing.
※Results vary depending on the usage environment.
Stays cold to the very end because it is dedicated to ice
When ice is placed in a cooler, its cooling performance decreases for various reasons.
- Cold air escapes when taking food in and out
- Frequent opening and closing reduces cooling performance
- Ice deteriorates in melted water
Have you ever found the inside of your cooler soaking wet from melted ice water?
With an ice jug, you can store ice separately and take out only as much as you need, whenever you need it. Enjoy highballs, iced coffee, soft drinks, and more chilled anytime.
High cooling performance from the vacuum-insulated double-wall construction
The body features a stainless-steel vacuum-insulated double-wall construction.
It is less affected by the outside temperature and keeps ice for a long time, even at hot summer campsites or inside a car.
It resists condensation, making it comfortable to carry and use on a table.
Surprisingly effective for heat retention
The ice jug is designed not only to keep things cold, but also to retain heat.
Heat retention test results (1 gallon)
※Test conducted with water at 93.3°C
- After 4 hours: 77.3°C
- After 8 hours: 72.7°C
- After 16 hours: 61.5°C
- After 24 hours: 54.3°C
Water added in the morning stays hot until night, making it useful for winter camping and sleeping in your car.
Also recommended for those who want to keep hot water on hand for coffee or cup noodles.
※Results vary depending on the usage environment.
