Features:

1.This large ice pack features a self-absorbent polymer resin cloth cover that ships dry and absorbs water instantly upon soaking, drastically reducing package weight for easier transport and storage.
2. The unique sub-box structure of this reusable cold wrap ensures even heat distribution, offering superior cold therapy compared to traditional gels. It forms a slushy texture in just 1 hour of refrigeration and fully freezes in 2 hours (compared to over 4 hours for gels). At the same time,microwave heating eliminates leakage risks thanks to its air hole design.
3. The sub-box structure allows the hot cold compress therapy pack to be freely folded and tied up, making it lightweight and portable for outdoor use. It easily applies to complex body areas such as the back and joints, providing pain relief anytime, anywhere.
4. Each independently frozen sub-box provides extended phase-change energy, maintaining cold temperatures for prolonged periods. This delivers deep cold therapy for sports injuries and muscle fatigue.
5. Fully reusable, the cold & hot wrap can absorb water again (soaking for over 30 minutes) after water evaporation, extending its lifespan and minimizing waste.
6. Both inner and outer materials are environmentally friendly, using biodegradable polymer resin inside and specialized composite fabric outside. From production to disposal, this ice wrap adheres to green principles throughout its lifecycle.
7. Designed for multi-body part use, including legs, knees, arms, back, and shoulders, this cold & hot wrap offers whole-body cold and heat therapy solutions. Whether for outdoor sports or at-home care, it quickly alleviates pain and enhances rehabilitation efficiency.

Features:

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.
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.
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.
4. Each individually frozen grid in the neck ice pack wrap provides prolonged phase-change energy for the duration of the cold compress.
5. When moisture evaporates, this polymer resin ice pack is reusable. Through re-soaking (30+ minutes) and absorbing water, it can restore full functionality.
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.
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.
