<p>Features:</p><p>1. This reusable ice pack features a self-absorbing polymer resin fabric that is shipped completely dry. Simply soak it to absorb water, which reduces its shipping weight for easier storage and transport.</p><p>2. For a hot compress, the grid structure of our large neck ice wrap ensures even heating distribution, and it is safe to microwave with no risk of leakage or bursting. For a cold compress, its efficiency far exceeds that of traditional gels. It freezes completely in 2 hours (vs 4+ hours for gel packs) and cools to a slush-like state in 1 hour.</p><p>3. The segmented grid design of this polymer resin cold compress pack allows it to be folded or bound flexibly and easily applied to target areas. Its lightweight design enables it to be portable for outdoor use.</p><p>4. Each individually frozen grid in the neck ice pack wrap provides prolonged phase-change energy for the duration of the cold compress.</p><p>5. When moisture evaporates, this polymer resin ice pack is reusable. Through re-soaking (30+ minutes) and absorbing water, it can restore full functionality.</p><p>6. The inner and outer materials are both environmentally friendly: biodegradable polymer resin interior and specialized composite fabric exterior. The concept of environmental protection is implemented throughout the entire process, from production to disposal.</p><p>7. Designed as an ice pack for injuries, it conforms to shoulders, neck, and upper back for hot/cold therapy during sports recovery or home care.</p><br/><p>Specifications:</p><p>Product Name: Hot and Cold Compress Shoulder Wrap</p><p>Product Material: Polyester Pongee + Polymer Resin</p><p>Colour: Dark Green (colour after absorbing water)</p><p>Net Weight Before Absorbing Water: 101g</p><p>Takes approximately 3 minutes to fully absorb water</p><p>Weight After Absorbing Water: Approximately 942g</p><p>Microwave Heating Time: 2 minutes</p><p>Refrigerator freezing time: 2–4 hours (after 1 hour in the refrigerator, it will become slushy; after 2 hours, it will freeze into ice cubes)</p><p>Expanded size: 57x46 cm</p>
