The Atlantic Carry-on Expandable Hardside Spinner is lightweight but tough enough to survive any travel, toddler, or teen. And when you need space this carry-on expands another 2 inches all over, so go ahead and get those matching souvenir t-shirts. A TSA-compliant exterior lock protects against theft and unwelcome snooping. 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. Not only are you the Chief Fun Officer, saving your family from boring vacations with boring luggage. Now, it's like you're saving the planet too. This colorful spinner's inside lining and expansion materials are made using 9 discarded plastic bottles to repurpose waste and protect the environment. Inside, a divider and elastic straps hold things down and a super handy, water-resistant interior pocket keeps damp swimwear or dirty clothing from stinking up everything else inside. 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 the kids can push their own bag. Don't be fooled by how lightweight this spinner is. When it comes to durability, the only thing tougher than Atlantic luggage is you.
