GronG Launches Condensation-Resistant Ice Pack for Summer Sports and Heat Relief

Ultimate Life Co., Ltd. (Headquarters: Higashinari-ku, Osaka; President & CEO: Yuki Tanaka), a company engaged in the sale of supplements and training equipment, will launch a convenient 'ice pack' for sports-related issues on Saturday, July 18, 2026, under the 'GronG' brand on Amazon and other e-commerce sites. This product is designed to be filled with ice and water and applied directly to areas needing cooling. It can be used not only for icing joints such as elbows and knees—areas prone to strain during exercise—but also for heatstroke prevention during hot weather. Additionally, an 'Icing Supporter' for securing the ice pack will be released simultaneously.

Product Features

- Multi-layer structure reduces condensation and is gentle on skin

The outer layer uses a latex-free cotton-like fabric that is gentle on the skin, while the inner layer features a durable, waterproof material made of polyester and TPU (thermoplastic polyurethane). This multi-layer construction allows for mild cooling on the surface, making it skin-friendly and minimizing residual moisture from condensation.

- 6cm wide opening accommodates large ice cubes

The opening for filling ice and water has a diameter of 6cm, compatible with large ice cubes sold at convenience stores. This allows users to refill with ice purchased on the go, making it convenient for sudden injuries or overheating.

- Screw-type cap prevents water leakage

To prevent leaks, a high-seal screw-type cap is used. A silicone gasket inside the cap blocks gaps, ensuring a tight seal.

- Two sizes available for different body parts

The product comes in two sizes: S (450–500ml) and M (1,300–1,400ml). The S size is recommended for narrow areas such as wrists and ankles, or for children during sports. The M size is suitable for thicker areas like elbows, knees, and calves.

- Secure spot fixation with optional Icing Supporter

The separately sold 'Icing Supporter' allows users to securely fix the ice pack to knees or elbows. Made of neoprene, it offers excellent elasticity and thermal insulation.
