How do Booster Packs work?:
Booster packs are designed to complement standard cooling packs by extending the duration that they last per charge. It does so by having a lower operating temperature than standard packs, so the fully-charged booster pack will actually charge a standard pack when they are paired together!
How do Booster Packs charge?:
In order to achieve their lower temperature, Booster packs must be charged in a freezer. In a typical freezer unit Booster packs should charge fully within 30 minutes, and in any below-freezing environment 1 hour is long enough to guarantee a full charge.
How to use Booster Packs (in a Cooling Vest):
To use a Booster pack, slide one of the standard four-cell packs into each pocket of the vest. Then slide one of the three-cell booster packs in each pocket, on the outer side of the four-cell pack. You want the four-cell packs closer to your body; they hold a comfortable temperature of around 59 degrees F. The green booster packs are much colder; they're designed to keep the inner packs cool (without making you too cold) for longer periods.
And last but not least - because the 3-cell Booster pack replaces a Standard 3-cell pack, there's no additional weight added to a vest when using a Booster pack set!
How to Clean Cooling Packs:
GlacierPacks can be hand-washed with warm water and dish soap. If desired, isopropyl alcohol may be used for disinfection. Rinse and towel dry before use.
How to Store Cooling Packs (for Long-Term Storage):
- A cool, dry space such as a pantry or dry storage is the ideal area to store cooling packs for weeks/months at a time.
- Long-term storage in a freezer can degrade the pliability of plastic over time, which makes the cooling packs more vulnerable to leaking and damage to the plastic that contains the cooling gel.
- We recommend considering long-term storage for any non-use period greater than 3-4 weeks.
