Alpen Outdoors to Release "Lightweight Vacuum Insulated 6-Side Cooler 30" on June 19: Keeps Ice for 6 Days at Just 2.3kg

Alpen Co., Ltd. (Headquarters: Nagoya, Aichi; President: Mitsuyuki Mizuno), a leading retailer of outdoor and sporting goods, will launch the "Lightweight Vacuum Insulated 6-Side Cooler 30" from its private brand "Alpen Outdoors" on Friday, June 19, 2026. This product balances top-tier cooling performance with exceptional lightweight design.

### 6-Side Vacuum Insulation at 19,990 Yen (Tax Included) Alpen Outdoors developed this product to provide a comfortable summer camping experience. It aims to surpass hard coolers in insulation performance while remaining light enough for anyone to handle and affordable for a wide range of customers.

### 6-Side Vacuum Insulation Structure Keeps Ice for 6 Days By employing vacuum insulation panels on all six sides, the cooler thoroughly blocks external heat. In testing, it achieved a remarkable record of approximately 149.5 hours (6 days) until the ice completely melted. Even under harsh conditions of 35°C (95°F) ambient temperature, it can maintain ice for 72 hours, ensuring items stay cold throughout multi-day trips. *Test Conditions: 40% ice-to-capacity ratio; repeated cycles of 30°C for 9 hours and 20°C for 15 hours until ice disappearance at 149.5 hours.

### Efficiency Through Lightweight Vacuum Panels Traditionally, high-performance hard coolers required thick insulation material to improve cooling, which resulted in bulkier and heavier products. This product utilizes extremely thin yet highly efficient vacuum insulation panels on all six sides. This allows for superior cooling power while minimizing wall thickness, achieving a lightweight design of just 2.3kg without compromising performance.

### Practical Design for Easy Loading Equipped with side handles, the cooler is designed for easy transport and smooth retrieval from car trunks, even when fully loaded. This design reduces stress for users during movement and setup at campsites.
