4MYTU Tank Suitcases Set in Navy (Carry-On + Trunk) Review — Is It Worth It? [2026]
.jpg)
4MYTU Tank Suitcase Set
A matching Tank Carry-On and Tank Trunk that nest together, priced below buying the two separately.
Is the 4MYTU Tank Suitcase set worth buying?
If you want both a carry-on and a check-in, the set is the obvious route. Buying the Tank Carry-On ($375) and Tank Trunk ($485) separately comes to $860, so $799 saves $61. The carry-on nests inside the trunk when you are not traveling, and the pair covers anything from a long weekend to a two-week trip. If you only need one size, buy that size and skip the set.
Two suitcases, one purchase
The Tank Suitcases set bundles the Tank Carry-On, described as the smallest carry-on in the series, with the Tank Trunk, the smallest check-in size. The store lists it in several colors; this review uses Navy.
What makes it stand out
34L front-opening carry-on
Front access and a laptop pocket for up to 16-inch laptops. It expands to 42L and weighs 8.55 lb.
82L 27-inch check-in
Top-opening, expandable to 96L and weighing 10.83 lb. The page suggests 7 to 15 days of clothes.
Nesting storage
The carry-on fits inside the trunk, which is nice if you live in a small flat. The page recommends the set for 10 to 20 days of travel.
Same features across both
Polycarbonate shell, spinner wheels, TSA lock, USB-A and USB-C ports (bring your own power bank), recycled lining and a cup-holder handle on both.
