Large Ice Pack for Back & Muscle Relief – Reusable Hot & Cold Compress Therapy
Experience convenient, effective cold and hot therapy with our 13x22 inch large ice pack, designed to soothe sore muscles, joint discomfort, and everyday fatigue. Perfect for use at home, in the office, or on the go, this reusable cold pack delivers fast, flexible relief wherever you need it.
Superior Cold & Hot Therapy
Unlike traditional gel packs, this innovative ice wrap features a self-absorbent polymer resin cloth that ships dry and absorbs water instantly, making it lightweight and easy to store. The unique sub-box structure ensures even heat and cold distribution, creating a slushy texture in just one hour in the fridge and fully freezing in two hours. When microwaved, the pack heats safely without leakage thanks to its smart air hole design.

Portable & Flexible Design
The flexible sub-box construction allows the pack to bend, fold, and secure comfortably around complex areas such as your back, shoulders, knees, and hips. Lightweight and portable, it’s ideal for outdoor activities, sports recovery, or on-the-go relief after long days.
Long-Lasting Relief
Each frozen sub-box delivers extended phase-change energy, keeping temperatures steady for deeper, prolonged cold therapy. Perfect for easing muscle fatigue, swelling, or minor bruises, this pack supports your active lifestyle with consistent, reliable comfort.
Eco-Friendly & Reusable
Both inner and outer materials are environmentally friendly, using biodegradable polymer resin and specialized composite fabric. This pack can be reused many times—simply soak for 30+ minutes to restore full absorbency—minimizing waste while staying effective.
Versatile Whole-Body Use
Designed for multiple body parts, this pack is perfect for legs, knees, arms, back, and shoulders. Whether you’re recovering from sports activities or seeking soothing warmth, it delivers customizable cold and hot therapy for a complete at-home spa or recovery experience.
