HVN-400U - Class 2 Cooling Vest
The default for general construction. Ships complete with fans, battery, and cable.
No sun, but no breeze either — heat builds all shift with nowhere to vent.
Warehouse heat is easy to underestimate because there's no sun involved. But a building full of product, forklifts, and dock doors that open and close all day traps heat with nowhere for it to go. Ceiling height and poor airflow mean the hottest air often sits right at working level, not up near the roof.
Unlike an outdoor job, there's no shift to a shaded spot — pickers move through the same enclosed aisles all day, and the back dock, often the hottest zone in the building, is usually the assignment nobody wants. The heat builds steadily across a shift rather than peaking and easing with the sun, so by the afternoon it's often worse than it was at midday.
High-visibility: Facilities with forklift and pedestrian traffic sharing the same floor typically specify ANSI/ISEA 107 Class 2. Check your facility's PPE policy — larger distribution centers often have a plant-wide hi-vis requirement regardless of role.
Fall protection: Not typical for most warehouse floor work. Where mezzanine or elevated rack work requires a harness, ZIPPKOOL garments are compatible — the rear opening passes the dorsal D-ring through without affecting fit.
Battery certification: LI-PRO1U is ETL Certified by Intertek, an OSHA-recognized NRTL. Many distribution centers require NRTL certification before permitting battery-powered devices on the floor — confirm with your facility's safety team.
The default for general construction. Ships complete with fans, battery, and cable.
For crews working near traffic or where Class 3 is specified.
Airflow inside the helmet, plus a neck and ear shade. Runs on AA or the same lithium-ion pack as the garments.
THE CASE FOR IT
Personal airflow works where the building's ventilation doesn't reach.
No trip to a break room mid-shift to swap a warm pack.
The back dock stops being the shift nobody wants.
Fans and battery add little weight to a picker walking miles a shift.
Plug in at the end of a shift, ready for the next one.
Where it doesn't belong
Running fans inflate the garment. Around conveyors, sortation equipment, or other exposed rotating parts, switch fans off and keep the garment zipped.
ZIPPKOOL garments are not flame-resistant. Not for use in maintenance areas doing welding or cutting, or anywhere FR-rated clothing is required.
Not rated for areas with flammable gases, vapors, or combustible dust — relevant in some cold-chain or chemical storage facilities.
Supplements — doesn't replace — hydration, rest, shade, and acclimatization, even in a building with a roof over it.
FAQ
The specification and compatibility questions that come up most.
Most warehouse and distribution center floors specify Class 2. Check your facility's PPE policy — some larger sites apply a plant-wide requirement regardless of specific role.
LI-PRO1U is ETL Certified by Intertek, an OSHA-recognized NRTL. If your facility requires NRTL certification for battery-powered equipment, specify LI-PRO1U.
Only with the fans off and the garment fully zipped. Running fans inflate the garment and increase entanglement risk near any rotating machinery.
