PCM Phase Change Cooling Neck Ring with Leakproof TPU Material for 1-3 Hours Cooling and Heat Relief

This PCM phase change cooling neck ring is a lightweight, hands-free cooling accessory designed to provide effective heat relief during summer months. Engineered with advanced thermal technology, it offers comfortable cooling without the harshness of direct ice contact.

Filled with high-performance phase change coolant, the neck ring solidifies after 20-30 minutes of refrigeration and provides soft, constant cooling for 1-3 hours. This innovative technology avoids harsh icy stimulation to your skin while maintaining optimal cooling performance.

• Crafted from flexible leakproof TPU material
• Seamless design closely fits the curve of your neck
• No dripping condensation or garment soaking
• Requires no charging or refilling
• Reusable for thousands of cycles with simple freezing

The cooling neck ring effectively cools blood vessels on the neck to relieve stuffiness and prevent heatstroke. This makes it ideal for long-hour outdoor work, sports activities, and daily commuting in warm weather conditions.
