Cooling Pack Vests & Accessories
There is no single "best" cooling vest, only the best one for how you live and where you'll use it. There are really just two choices to make: which cooling technology fits your routine, and which vest style fits your day. Here's how they compare.
Step 1: Choose your cooling technology
Reusable cooling packs
Kool Max®
The highest level of cooling energy. Frozen water-based packs charge in a standard freezer.
- Freezer needed: Yes
- Charge time: 2 to 3 hours in a freezer
- Cooling time: Vest ~3 to 4 hrs; accessories ~1 to 2 hrs
- Cooling energy: Highest
- Best for: Home, work, anywhere with freezer access
Phase-change packs
Cool58®
A comfortable, constant 58°F. Recharges without a freezer, so it travels anywhere.
- Freezer needed: No
- Recharge: 15 to 20 min in ice water, or 1 to 1.5 hrs in a fridge or freezer
- Cooling time: Vest ~2 to 3 hrs; accessories ~1 to 1.5 hrs
- Temperature: Steady 58°F (14.4°C)
- Best for: Travel and no-freezer situations
Best of both
Home & Away Kit
A vest plus each style of pack, so you're covered either way.
- Includes: One vest, a set of Kool Max packs, a set of Cool58 packs
- Kool Max: for when you have a freezer
- Cool58: for when you're traveling with only a cooler of ice water
- Best for: Anyone who wants both options

Step 2: Choose your vest style

- Colors: Khaki, blue, gray, black
- Cooling: Back packs sit along the spine, packs on chest in front
