Macna Cooling vest Hybrid Grey

The Hybrid Cooling Vest is lightweight and easy to (re)activate.
The vest is suitable for multifunctional use, such as during work
sports and for recreational applications.

The Hybrid vest is designed to be worn in places where there is no extremely high ambient temperature and works best at low to medium humidity. The amount of air flow on the body determines the cooling effect and the duration of cooling.

By immersing it in water, the Hybrid vest can be used as a wet cooling vest, but is also prepared for the separately available Macna Cool Packs. These are available in 21˚ and 29˚ versions.

Activation - Nat

Immerse the product in water for 1 to 2 minutes.
Then gently squeeze out the excess water.
Finally, wipe the water-repellent lining (vest/headwear) dry with a towel before use. And you're ready to go!

The Hybrid Cooling Vest cooling material has been developed for up to 200 wet/dry cycles (activations). Over time, water absorption decreases because the fibers cluster together in the fabric structure.

After the first 10 wet/dry cycles, a reduction in water absorption may occur; after this the absorption remains relatively stable. This is a normal process. The material still offers very effective water absorption, evaporation and therefore cooling capacity.

The degree of absorption is also influenced by the method of maintenance of the product and the water quality.

Activation - Cool Packs
The time required to fully activate them depends on the Cool Pack temperature and cooling method:

Ice water: approximately 20 minutes
Freezer: approximately 40 minutes
Refrigerator: approximately 60 minutes

You can also activate them by exposing them to an ambient temperature lower than:

19°C for the Cool Pack 21°C
26°C for the Cool Pack 29°C

Whichever cooling method you choose, you can shorten activation time by
not to stack packs, but to lay them flat in a single layer. If you want to use them straight from the freezer, they may feel too cold to wear. It is therefore recommended that you wait at least five minutes to allow them to warm up to their set temperature of 21°C or 29°C, depending on the type of PCM you have chosen. Once the PCM reaches this temperature, it will hold it for hours!
