Experience fast, targeted hot and cold relief for your back, knees, and legs with a self-absorbent wrap that ships dry and activates with water.
Self-absorbent design and activation: Self-absorbent polymer resin cloth cover ships dry and absorbs water instantly upon soaking, drastically reducing package weight for easier transport and storage.
Even cooling and quick readiness: The sub-box structure provides even heat distribution; forms a slushy texture in about 1 hour of refrigeration and fully freezes in about 2 hours. Microwave heating reduces leakage risks thanks to an air-hole design.
Portable, flexible application: The sub-box structure folds and ties, making it lightweight for outdoor use and easy to adapt to the back, knees, arms, or shoulders.
Reusable, eco-friendly and specs: Biodegradable polymer resin inside with a specialized composite fabric outside; independently frozen sub-boxes deliver extended phase-change energy; expanded size about 58 × 35 cm; packing includes 2 elastic straps (≈78 cm) and an English instruction manual.
