The largest case in this pink set opens up to 114 L, and that number is worth reading before the inches are: a 28-in shell can mean anything between 90 and 120 L depending on how the corners are cut, and 114 L is at the generous end for trips of 7 to 9 days. It measures 20 in by 11.5 in by 31 in at a case weight of 9 lbs empty. Stepping down, the 24-in case holds 76 L at 6.5 lbs across 18 in by 10 in by 27 in for 4 to 7 days, and the 20-in case holds 37 L at 4.5 lbs across 12 in by 8.5 in by 22 in for 1 to 4 days, rated as airline standard carry-on so it can stay in the cabin while the other two go as checked baggage. All three are ABS with a robust hardshell that is scratch-resistant and impact-resistant, which matters more in pink than in black, since scuffs show against a light finish. Each case rolls on 360 degree double spinner wheels that stay silent, smooth, reliable, and flexible under load, and a sturdy adjustable telescoping handle sets the towing height while reinforced grab handles take the lift. Inside, multiple compartments keep belongings tidy and accessible, smooth zippers open and close the case without snagging, and a secure 3-digit lock increases safety. Between trips the nesting design stacks the smaller cases inside the larger, so the 21 lb set stores in about the space of one case.
