Product Description
Specifications & Descriptions:
Name: Ultra-thin Crystal Cooling vest
Weight: 160-200g (dry condition)
Outer carrier Material: 100% polyester
Cooling material: Cooling crystals
Size: S-5XL Style: air mesh style or customized styles according to customers' requests.
Features:
1. Cooling crystal is a kind of new cold storage materials, which use liquid gas phase transition of water (latent heat of phase transition is 2430J/g). Compared to those traditional cold storage materials, such as water gel, hard gel, ice sand gel and PCM materials, the new cooling crystals' cold storage volume is 7-20 times than them.
2. The cooling crystals can maintain a certain shape after absorbing water, and will not flow to the human body and cause discomfort when the clothes are slightly torn.
3. After absorbing water, the cooling crystal has a soft nature, which can increase its fit and wearing comfort.
4. Environmental protection: After being discarded, it naturally degrades in the soil within 3-5 years, is harmless to the environment, and is environmentally friendly.
Usage:
1. Soak the cooling vest or cooling modules in water for 10-15 minutes until the cooling module is visibly bulging.
2. Take the cooling vest out from the water; drain the free water on its surface before wearing and using it. It can be dried in the washing machine for 1-2 minutes or hung for a certain period of time.
