Cooling Technology

The vest uses Phase Change Material (PCM) or Evaporative Cooling Technology to regulate body temperature. PCM inserts absorb and release thermal energy within a defined temperature range for stable cooling, while evaporative systems use water evaporation heat transfer to dissipate heat from the body surface through continuous airflow and moisture exchange.

Product Features

Adjustable fit structure with straps or elastic panels helps distributors reduce SKU complexity and improve inventory flexibility.
Lightweight construction improves wearability during extended work shifts and supports productivity in hot environments.
Multiple cooling system options (PCM or evaporative) allow buyers to match products with different climate and industry requirements.
Washable vest shell design supports repeated use and extends product service life.
