01Start with empty weight, because the scale at check-in does
Delta and the other big US carriers publish the same standard for a checked bag on a regular ticket: 50 lb and 62 linear inches. A suitcase that eats 12 lb of the allowance before you pack a sock is the easiest way to go over, so empty weight comes first. It runs against intuition: the cheapest and the most expensive bags here are the heaviest.
The large bag in the Freeform 2-piece set is the same case as the Freeform 28, so its row covers the set too. The spread is about 2 lb. Liters per pound matters more: the Freeform gives you 12 L for every pound of bag, the Sion under 8. If you pack to the limit, the Freeform lets you use the allowance. And note OutdoorGearLab's warning about the two biggest bags: the Platinum Elite and the Freeform both hold enough to pass 50 lb with ordinary clothes, so weigh the packed bag at home.
02The 62-inch rule, and which bags actually meet it
Airlines measure length plus width plus height, wheels and handle included, and almost every 28 or 29-inch spinner overshoots on paper. Travelpro lists the Platinum Elite 29 at 32.5 x 21 x 13.25 in overall, 66.75 linear inches. Samsonite lists the Freeform 28 at 31.1 x 20.9 x 13.8, about 65.8, and gives the same 65.8 for the large bag in the Freeform set. SwissGear lists the Sion at 30 x 18.5 x 12.5, which is 61 and inside the rule.
In practice a standard spinner is rarely put to a tape measure, but the risk rises with the bag, and if you fly strict carriers the Sion is the only pick that clears the rule on the maker's own numbers. Fly with the expansion zipped closed unless you need it; an expanded 29-inch bag is past any limit and harder to keep under 50 lb.
03Shell material: what each one does when it hits the belt
The picks use three materials, and OutdoorGearLab's drop, tumble and hose tests show how each fails.
Polypropylene (Freeform). The lightest common shell plastic. It bends under impact rather than cracking, which is why the Freeform survived the drop tests, but it scratches readily and has no corner bumpers. OutdoorGearLab's sample was heavily marked after the test cycle, and its unsealed main zipper let water in under simulated rain. Buy it for weight and space, and accept a suitcase that looks used after two trips.
Polypropylene again (Freeform set). Both pieces of the Freeform 2-piece set use it. CNN Underscored's hammer blows left no dent or crack, but a concrete wall cut the surface; Good Housekeeping's drop tests left no major damage.
Polyester (Sion). Thin and soft enough to absorb knocks that would mark a hard shell, but the fabric soaked through in OutdoorGearLab's hose test and the site expects it to wear faster under frequent use.
Coated nylon (Platinum Elite). The thickest fabric here. OutdoorGearLab's stair drops produced only corner scuffs and the zippers kept water out, the only bag of our four that passed that test. The cost is weight and price.
The rule of thumb: hardsides resist crushing and, on the two Samsonites, put the lock in the case; softsides give you outside pockets and hide cosmetic damage. Neither keeps rain out unless the zippers are sealed, and only the Travelpro's are.
04Wheels and handles: the parts that break first
Wheels fail first, then trolley handles, then zippers, and this is where the four picks separate most clearly.
The Travelpro rolls on eight wheels in four self-aligning pairs; magnets pull each pair straight when the handle is released. OutdoorGearLab scored its ease of transport 9 of 10 and called it the best-rolling bag it tested, on an aluminum handle with four stops from 36 to 42.5 in. The Freeform has four double wheels with rubberized tread that OutdoorGearLab found track straighter than older Samsonite designs; its trolley handle was rated adequate and its grab handles thin. Both pieces of the Freeform set use the same double wheels, which Good Housekeeping's and CNN Underscored's testers found smooth. The Sion uses four single wheels, and OutdoorGearLab found them noisy, prone to drifting and poor on gravel, although the Sion's handles were rated better than the Freeform's.
If you roll a full bag through big terminals every month, the Travelpro's wheels are the biggest reason to pay for it. A few curb-to-desk trips a year, and the Freeform's double wheels are enough.
05Warranty: read what is covered
Three of the four say ten years, and none covers a wheel torn off by a baggage handler. Travelpro's warranty names the parts that actually fail and, once registered, extends to airline damage. NewCarryOn's long-term coverage of SwissGear describes slow and sometimes refused claims, so the Sion's ten years is a backstop, not a plan. A checked bag lives a harder life than a carry-on, which makes the Travelpro's terms worth more here than on our carry-on list.
06One bag or a set
A set makes sense only if every piece will be used. The Freeform 2-piece set is our top pick's large bag sold with the matching Freeform carry-on, so a couple or a small family can pool clothes in one checked bag and keep one carry-on for the flight. CNN Underscored named it the best budget luggage set of 2026, and Good Housekeeping's Textiles Lab included it in its April 2026 set roundup. If you need only the checked bag, buy the Freeform 28 on its own.
The carry-on shares the large bag's flaws, and Samsonite lists it at 23 x 15 x 10 in overall, an inch over a 22 x 14 x 9 in sizer on every side. A family where everyone checks a bag needs more than two pieces; the three-piece sets we looked at had either left the maker's own store or were missing from both 2026 set tests.
