Reference Price: ¥6980 Size: 58L Brand: MYS&CIE Color: Black Material: EVA Insulation Foam, Aluminum Vapor Deposition Sheet, Polyester (High-Density PVC Coating) Package Information: Bag Capacity: 58 Liters Product Dimensions: 39cm Depth x 36cm Width x 49cm Height 【PRO's Choice】 Chosen by "high-earning delivery drivers," a tough design that blends into the city. The MYSCIE PRO model achieves a high level of balance between **"lightness, durability, and ease of use"** demanded in urban delivery environments. The frameless design features an intermediate partition structure that prevents collapse, making it incredibly easy to load and unload items. The exterior is made of **high-water-repellent material × leak-proof construction** that meets JIS standards, and the interior features **insulation foam + tear-resistant aluminum vapor deposition** to maintain temperature effectively. Three-sided reflectors enhance nighttime safety. It's equipped with all the "must-have" features for the job, including a 10x22cm side pocket and SBS waterproof zippers. 【Astonishing Lightweight & Self-Supporting Structure】 Doesn't sag or fall over, even at 1.4kg. Approximately 1.4kg for 42L, and approximately 1.7kg for 58L, offering **astonishing lightness**. To prevent the "sagging" unique to frameless designs, it is designed to stand firmly on its own with **thick partitions, reinforced bottom, and a stable center of gravity**. Even when carrying food, the bag is less likely to tip over, significantly reducing work-related stress. 【Fatigue Reduction】 Zero heat buildup with 3D mesh. The back is designed to prevent "back sweat," employing **uneven pads × 3D mesh × vertical air channels**. This creates a natural airflow between the back and the bag, significantly reducing heat buildup and sweating, which are common during long hours of operation. Thick, soft cushioning distributes the load, reducing fatigue on the shoulders and lower back. "Optimal Capacity" selectable by purpose. **■58L: Main unit for heavy-duty operation (pizza, large order support)** ・Closed: D10 x W39 x H49cm ・Open: D36 x W39 x H49cm ・Weight: Approx. 1.7kg *Based on external dimensions / Sewing error ±1-2cm 【Care Instructions (Tips for Longevity)】 * The interior is tear-resistant aluminum, making it easy to wipe clean. * Care for stains with a wet cloth → dry cloth. * Store after thoroughly drying to prolong its life. * Food and small items in the photos are for illustrative purposes and are not included.
