Unique design—1. The front pocket has a clear window for easy viewing and operating the machine at any time; 2. The position and direction of the infusion tube can be adjusted through a two-way zipper; 3. The backpack comes with a small pouch featuring a thick thermal insulation layer to hold the infusion bag, ensuring the nutrient solution stays warm for a longer period; 4. The backpack is made from water-resistant fabric (excluding the zipper), with the main compartment lined with aluminum foil, providing not only thermal insulation but also making it easy to clean.
