Optimized for adaptability, the Optima Expandable Carry-on Hardside Spinner delivers performance without the bulk. Designed for efficient travel, this sleek spinner features a lightweight, crack-resistant shell made from ultra-resilient polypropylene-resilient where it counts, light where it matters. Plus, a zippered expansion gives up to 2 extra inches of packable space on demand. Inside, everything is designed for optimal efficiency. A built-in compression panel fits more in less space, while a zippered divider, water-resistant compartment, and interior pockets keep contents sorted and easy to find.
