SWEDE Cooling Vests are the best solution to reduce and combat heat stress. SWEDE Cooling Vests use PhaseCore, a phase change material (PCM), to provide a cooling effect to the body’s core by absorbing body heat.
Includes: SWEDE Vest, PhaseCore 28 (set of 22).
PLEASE NOTE: All PhaseCore Cooling Vests, Hat Liners, and Elements are on backorder due to a busy summer. First Line Technology will be accepting backorders and fulfilling orders as soon as Elements are back in stock. Thank you for your patience and business.
Recharges Without Ice, Water, Refrigeration, or Electricity
How does it work?
SWEDE Cooling Vests are fitted with a set of (22) PhaseCore 28 elements, which have an activation point of 82.4°F (28°C). When the body temperature rises above this point, the elements begin to absorb body heat. When heat is absorbed, the PhaseCore elements provide a comfortable and soothing cooling effect. SWEDE Cooling Vests hold PhaseCore elements close to the body allowing them to absorb heat most effectively.
Is it Effective?
Tests completed in a hot environment showed that an individual wearing a SWEDE Cooling Vest with PhaseCore 28 experienced only a 3.6°F (2°C) rise in body surface temperature while an individual without a SWEDE Cooling Vest experienced a 12.6°F (7°C) rise in body surface temperature. SWEDE Cooling Vests are effective for up to 4 hours, actual time varies based on physical activity, body type, and the environmental conditions.
How does it recharge?
SWEDE Cooling Vests can be recharged by storing the PhaseCore elements in an environment less than the activation point. PhaseCore elements can be recharged more quickly in colder environments. Refrigeration is not required, but will make the recharge period shorter. PhaseCore elements are completely recharged when they return to a solid state. PhaseCore is simple, safe, and reusable.
