The two main compartments are equipped with double-sided explosion-proof zippers, allowing for neat storage of 5-7 outfits while preventing contents from scattering. Two transparent mesh pockets allow for organized storage of small items such as passports and chargers. The waterproof wet & dry pocket completely separates swimwear and wet towels from clean clothes. 【High-Quality Aluminum Frame & 360° Silent Casters】 This suitcase uses a combination of lightweight, tear-resistant ABS resin and impact-resistant PC resin, with a wide aluminum frame design, creating a sturdy and durable hard shell.
