Brand: HPI
Product Name: HPI Cool Vest — Replacement Vest Body
Line: HPI Cool Vest / Cool Seat system
Role: Replacement vest body + fittings

Kit contents: vest body, 2 × Ø8–Ø10 unions, 2 × Ø6 vacuum hose (75 cm), one female quick-connect. Vacuum hose can be trimmed to the length you need.
The replacement vest body for HPI’s cooling system — the garment itself with the fittings but not the pump or bottle. Used to refurbish a system whose vest has reached end-of-life.
Features:
- JAXA-Developed: Design co-developed with Japan’s space agency for operator cooling.
- Pumped Water Loop: About 16 m of silicone tubing circulated by a battery-driven pump.
- Reusable Chiller: Freeze an ordinary PET bottle and drop it into the unit.
- Portable: Battery-powered — no cables, use anywhere.
- Whole-Garment Knit: Woven as a single piece so the tubing stays in position.
For refurbishing an existing HPI cool-vest install.
