Coolife 20" Carry-On: Dimensions, Weight and Material, Checked Against Airline Limits
By Brandon Schultz Published
Coolife calls the 20" PC+ABS Carry-On, Black Brown a 22x14x9 airline-approved case. That is the number most people search for, so this page puts Coolife's own measurements next to the limits three big US airlines publish, then answers the weight and material questions that come up right after.

| Question | Answer from Coolife |
|---|---|
| Size named by Coolife | 22x14x9 in, "carry-on ready for most major U.S. airlines" |
| Measurements in Coolife's spec table | 21.7 in tall, 15 in wide, 8.5 in deep |
| Weight | 7 lb |
| Capacity | 38 liters |
| Shell | PC+ABS hardshell |
| Expands? | No. This Black Brown case is from Coolife's Original Collection, where only the 28" expands |
Coolife's own advice sits alongside the 22x14x9 claim: check your airline's size limits before you travel. The next section shows why that step is worth two minutes.
Will it fit American, Delta and United?
All three airlines publish a 22 x 14 x 9 in carry-on limit and count wheels and handles in that measurement. Here is how Coolife's spec-table numbers line up, checked on each airline's site on October 18, 2026:

| Airline | Published carry-on limit | Height (21.7 in) | Width (15 in) | Depth (8.5 in) |
|---|---|---|---|---|
| American | 22 x 14 x 9 in (56 x 36 x 23 cm), including handles and wheels, and it must fit the airport sizer | Within 22 | Over 14 by 1 in | Within 9 |
| Delta | 22 x 14 x 9 in (56 x 35 x 23 cm), including handles and wheels, and no more than 45 linear inches (114 cm) combined | Within 22 | Over 14 by 1 in | Within 9 |
| United | 9 x 14 x 22 in (23 x 35 x 56 cm), including handle and wheels | Within 22 | Over 14 by 1 in | Within 9 |
On paper, height and depth are fine. Width is the number to watch. Coolife's product name says 14 in, while its spec table says 15 in, and it doesn't say whether either figure includes the side handle and wheel housings. Delta's combined limit is also tight: 21.7 + 15 + 8.5 comes to 45.2 linear inches, against Delta's 45.
So before your first flight, measure the case yourself. Stand it up, run a tape across the widest point, wheels and side handle included, and compare that with your airline's page. If you're within 14 in, you're set. If you're not, the gate agent may ask you to check it, and that's worth knowing before you're in the line.
For other airlines, check that airline's own carry-on page; limits differ, and some budget fares don't include a carry-on at all. Our carry-on size guide covers more US airlines and personal-item limits.
How heavy is it?
Coolife puts it at 7 lb empty. That's the case alone, before you pack anything. None of the three airlines above publishes a weight limit for a standard carry-on on their carry-on pages, but if you fly an airline that does, 7 lb is the starting point to subtract from it.
What is it made of?
The shell is PC+ABS, a polycarbonate and ABS blend. Coolife describes it as sturdy, scratch-resistant, pressure-resistant and hard to deform. The other parts Coolife names:
- Custom YKK zippers, which Coolife describes as smooth and wear-resistant
- A water-resistant lining
- A built-in TSA combination lock
- 360° spinner wheels, which Coolife calls quiet and reinforced
- A three-level telescopic handle and cushioned carry handles
If you want a 100% polycarbonate shell instead, Coolife's Expandable Front-Pocket Carry-On, Apricot uses one.
Does it expand?
No. Coolife's own FAQ for this case says expansion comes only on Original Collection 28" cases (15% more room) and on 20" colors marked "2.0" (20% more room). Black Brown isn't a 2.0 color, so its 38 liters are fixed. The upside is that the case can't bulge deeper when you overpack it.
What fits inside 38 liters?
Coolife gives the interior ten pockets, cross straps, a zippered divider and mesh pockets. Coolife pitches the case at business trips, short holidays and family trips, so think a long weekend of clothes, with a personal item for the rest.
