WORLD-BIO Water-Activated Extra Large Ice Pack for Full Back Pain Relief - size: 13"x21"

About this item

• WATER-ACTIVATED — ARRIVES DRY & FLAT: This ice pack is intentionally shipped dry and lightweight. Before first use, soak it in water to activate the absorbent filling. The internal material expands as it absorbs water. Then freeze before use. Soaking is required before the first use.
• Simple One-Time Activation – Not Repeated：This reusable ice pack only requires water absorption once during the first use. After activation, simply dry it and store it in the freezer—no need to repeat soaking. Convenient, time-saving, and ready for everyday cold or hot use.
• Extra-Large 21" × 13" Full Coverage Size：This oversized ice pack for cold therapy measures 21” x 13”, providing wide coverage for larger body areas. Perfect for full surface application, delivering even cooling or heating distribution where you need it most.
• Hands-Free Use with Adjustable Straps： Two adjustable elastic straps secure the full back ice pack in place, allowing you to enjoy hands-free relief while sitting, standing, or lying down. Its flexible design lets you move freely, making it easy to incorporate into your daily routine. While ideal for full back coverage, this large ice pack can also be wrapped around arms, hips, legs, or other areas as needed
• Segmented Grid Design： This ice pack features a grid design, with each grid cell functioning independently. When needed, it can be cut along the grid lines to remove the affected portion, while the remaining area continues to function normally. This modular design enhances usability and maintains overall functionality even with localized wear, thus extending the product's lifespan.
