High CP Value Buying Guide: 7 Luggage Recommendations | 2025 Latest

When going on an overnight business trip or vacation, choosing the right luggage is always a challenge. Selecting a suitable suitcase can make your entire trip worry-free. There's a simple formula to achieve this. With hundreds of styles on the market, the ideal combination varies greatly depending on factors like duration of stay, local season and weather, and purpose! Below, we've compiled key points for choosing luggage, suggested scenarios for selection, and summarized a 2023 high-CP value buying guide, featuring seven recommended suitcases for those who want to avoid the hassle.

Selection Point One: Size

Standard luggage sizes range from 16 inches to 32 inches. It's recommended to choose based on the duration of your stay. The general breakdown is as follows:

• 16 ~ 20 inches: 1 ~ 3 days for short stays, light travel, can also be used as carry-on.
• 21 ~ 24 inches: 4 ~ 6 days for a medium-length trip (about a week).
• 25 ~ 28 inches: 7 ~ 14 days for long trips (over a week).
• 28 inches and above: 15 days or more, for long-term stays, studying abroad, or working holidays.

If your family does not plan for long-term stays abroad, it is recommended to choose 20, 24, and 28-inch models as standard luggage to accommodate three common overnight situations. If you are concerned about longer stays or not being able to fit everything in one suitcase, you can also bring a suitcase under 20 inches as a carry-on or bring a luggage strap as a backup.

Selection Point Two: Material (Hard Shell, Soft Shell)

The outermost material of luggage is usually divided into "hard shells" made of aluminum-magnesium alloy or plastic, and "soft shells" made of fabric or leather. It is recommended to consider the destination's weather and the items you are carrying.

Hard Shell

• Advantages include sturdiness, impact resistance, good security, durability, and excellent waterproofing. It can effectively protect laptops or fragile items, reducing the risk of damage to high-value items and theft. If you encounter rainy seasons and want to keep the inside of your luggage dry, a hard shell is recommended.
• Disadvantages include less flexible space and a relatively heavier weight compared to soft shells. If you have too much luggage that you want to cram in, it's almost impossible with a hard-shell suitcase.

Soft Shell

• Advantages include flexible space, good expandability, and lighter weight compared to hard shells. Soft shells usually have internal and external storage spaces and predominantly feature single-sided opening, making it relatively easier to access items on the go. Recommended for short overnight stays, shopping trips, or when you need to keep your luggage close at hand.
• Its disadvantages correspond to the advantages of hard shells.

Selection Point Three: Opening Mechanism (Aluminum Frame, Zipper)

Opening mechanisms are divided into two types: aluminum frame and zipper. It is recommended to choose based on factors such as destination weather, items being carried, and purpose.

Aluminum Frame

• Advantages include good security and excellent waterproofing. The metal aluminum frame is less prone to damage and features a security lock, offering higher security, so you can worry less about valuable items.
• Disadvantages include less flexible space, heavier weight, and high repair costs. Aluminum frame luggage often requires being laid flat and having sufficient space to open, making access to items less convenient, and it cannot accommodate overstuffed situations, as space utilization is more fixed.

Zipper

• Advantages include flexible space, light weight, and low repair costs. Zippered luggage usually does not need to be laid completely flat; you can reach for items through the zipper, offering greater flexibility for access.
• Disadvantages include poorer security and less waterproofing. Zippered luggage raises more security concerns, as it is relatively easier to damage or steal from. However, if your luggage stays close to you and you need a lot of flexible space, you might still consider a zipper type or an anti-theft zipper.

Selection Point Four: Empty Weight

Airlines have weight limits for international travel, and most people certainly don't want to pay extra for overweight baggage. Carry-on luggage also has a limit of 10 kg, and an overly heavy suitcase will directly reduce the amount of weight you can carry. Therefore, the empty weight of the suitcase is crucial. As mentioned above, the choice of material (hard shell, soft shell) and opening mechanism (aluminum frame, zipper) will affect the net empty weight. It is recommended to consider the intended use as well, such as whether you need to carry it up and down stairs. For light travel or business trips, a suitcase under 20 inches that can also serve as a carry-on is a good choice, aiming for under 3 kg to reduce the weight burden.

Selection Point Five: Component Design (Wheels, Locks, Handle)

Wheels

Luggage wheels range from a minimum of two to a maximum of eight. Two-wheeled luggage is lighter and more maneuverable, but if the luggage is heavy, it will significantly reduce gliding speed. While luggage with four or more wheels is heavier and less maneuverable, it becomes effective when carrying heavy loads, providing more stable gliding. If you have a strong need for heavy-duty capacity, consider models with single-leg double wheels, which offer the best stability.

The size of the wheels affects durability and stability; it's recommended to choose larger wheels. You can test stability by rotating the suitcase in place; the more spins it makes, the more stable it is. Also, try pushing it to observe the gliding distance and determine its resistance. The noise level of the wheels is also a key factor; if you're concerned about noise while dragging, choose a quieter model.

Locks

If you choose a frame-type suitcase, it usually comes with a combination lock. It's simple and convenient to use, but the space flexibility is relatively small, and you need to remember the password. Another type is a key lock, where the safekeeping of the key is crucial. Furthermore, after the 9/11 incident in the United States, all luggage entering the US is subject to customs inspection if any anomalies are found. Regular locks, which cannot be opened by customs, will be forcibly broken. However, with a TSA-approved customs lock, customs can directly open the suitcase with a special key. It is recommended to purchase a TSA customs lock to avoid the risk of damage.

Pull Handle

Pull handles are usually divided into single-bar and double-bar. Double-bar handles have more latches than single-bar ones, providing better support, but they are also relatively heavier. They are also categorized into internal and external pull handles. Internal pull handles are embedded within the suitcase, so the interior of the suitcase is affected by the handle, making storage difficult. External pull handles, on the other hand, provide a flatter interior space, but because the handle is on the outside, it may be damaged or deformed by impact.

Before purchasing, it is recommended to first confirm your needs for the pull handle: whether the height is appropriate, whether the latches operate smoothly without getting stuck, and to carefully check the material. Materials containing iron may rust over time. If you are concerned about the handle rusting, you can purchase a more expensive full aluminum alloy material.

Selection Point Six: Warranty

Luggage can be considered a consumable item; it may not be handled with care during transit. If you hope for long-lasting durability, it is recommended to choose higher-priced models with better brand guarantees and after-sales service. Alternatively, you can opt for a lower-priced model that you won't mind replacing if it breaks, which means you won't have to worry as much about warranty issues. You can choose based on your frequency of travel and usage needs.
