2 Pack Cooling Neck Wraps With Long Lasting Gel
Made of soft fabric with a self-cooling cool value of 0.25 and long-lasting cooling gel. The fabric is safe and skin-friendly, the gel part is flat and resistant to deformation. Suitable for all skin types, Can be used after about 20 minutes in the refrigerator. Achieves rapid cooling without over-irritating the skin. Enjoy coolness on hot days. (Due to the limited cooling duration of a single Cooling neck wrap, we recommend freezing 2 for rotation to maintain continuous cooling effectiveness.)
About cooling duration
Gel filling weight impacts cooling time. Experimental results show: Each +50g increases cooling duration by ~15% but significantly raises neck muscle fatigue. We use 110g±5g gel filling + 3mm ultrathin layer, achieving an optimal weight-to-performance ratio for coolness and comfort.
