Pack in maximum fun with a convertible spinner that works as hard as two bags and almost as hard as you do. The Atlantic Convertible Medium to Large Checked Expandable Hardside Spinner goes from medium- to large-size check-in bag whenever you need more space. Unzip the expansion zipper to have a large-capacity suitcase that can be used for multiple people and still meet check-in size restrictions for most flights (62 linear inches). Close the expansion zipper to keep the bag medium-sized. Along with being Chief Fun Officer, you're like a planet-saving hero too! The colorful spinner's inside lining and expansion materials are made from 15.5 post-consumer recycled plastic bottles. Yes, it is super lightweight, but when it comes to durability, the only thing tougher than this spinner is you. Inside, a super handy, water-resistant pocket keeps damp or dirty swimwear and clothing from stinking up everything else you packed, while elastic straps and a zippered divider panel minimize digging and the chorus of, Where's my stuff?!" Stave off theft and snoopy toddlers with TSA-compliant exterior lock that lets authorities inspect the bag without damage if needed. 360° wheels require almost no effort to move, instantly going where you want when you want, no cajoling or threatening to take away their cell phones required. Of course, the extension handle adjusts heights, so everyone can take a turn pushing.
