Dual‑wheel casters with precision bearings and a soft TPU tread glide silently over polished airport floors and cobblestone streets alike.

Molded Corner Guards

Impact‑resistant bumpers on all four bottom corners deflect shocks and protect the case structure from accidental drops.

Four purpose‑built sizes for seamless travel

Each bag is designed to nest inside the next for compact storage when not in use. Weights and dimensions reflect the careful balance between capacity and portability.

Ergonomic Telescopic Handle

The multi‑stage locking system adjusts to three distinct heights, accommodating travelers of different statures. The contoured grip is wrapped in a soft‑touch finish that reduces hand fatigue during long transits through terminals. Constructed from lightweight aluminum alloy, the handle retracts flush into the bag for a sleek silhouette.

  • Locking mechanism: Spring‑loaded push button with audible click

360° Dual‑Wheel System

Eight smooth‑rolling wheels (two per corner) distribute weight evenly and rotate independently, granting zero‑radius turns in crowded aisles. The TPU tread is engineered for silent operation—lab tested at under 55 dB on hard surfaces—and resists flat‑spotting even after prolonged stationary storage.

  • Wheel diameter: 2.36″ (60 mm) dual wheels
  • Bearing type: ABEC‑7 steel bearings
  • Housing: Glass‑fiber reinforced nylon

Smart Interior Layout

Each case opens wide with a U‑shaped zippered divider that keeps contents separated. On one side, a full‑panel zippered mesh pocket stores smaller items; the other side features adjustable compression straps that hold garments flat and reduce shifting. A dedicated wet/dry pocket in the tote and carry‑on adds practicality for toiletries or swimwear.

Heavy‑Duty Zippers

Custom‑branded reverse‑coil zippers with interlocking metal sliders run smoothly along every opening. The self‑repairing nylon coil can withstand over 10,000 open/close cycles without failure. Large zipper pulls are easy to grip, even with gloves.

Technical insights & Frequently Asked Questions

What materials are used in the soft shell?

The primary fabric is a 900D high‑tenacity polyester with a water‑repellent (DWR) coating. Interior lining is 150D polyester. Stress points are reinforced with PU‑coated nylon binding. The combination delivers an optimal strength‑to‑weight ratio while maintaining a pliable, shock‑absorbing exterior that protects contents from moderate impacts.

How much does the complete set weigh when empty?

The total unladen weight of all four pieces is approximately 26.1 lb (11.85 kg). Individually: Carry‑on 6.5 lb (2.95 kg), Medium 8.2 lb (3.72 kg), Large 9.9 lb (4.5 kg), and Tote 1.5 lb (0.68 kg). This places the HKM-933651 among the lightest full‑size soft luggage sets in its class.

Are the spinner wheels replaceable?

Yes. Each wheel assembly is attached with two screws and can be serviced or replaced without special tools. Replacement wheel kits are available directly from our support channel.

Does the carry‑on comply with major airline standards?

The 20‑inch carry‑on falls within the standard size limits of most U.S. domestic carriers (typically 22″ x 14″ x 9″). For international travel, we recommend verifying with your specific airline, as some low‑cost carriers enforce tighter restrictions. The external dimensions of 20.0″ × 14.0″ × 9.0″ include wheels and handles.

Is there an expansion feature?

The Medium 24″ and Large 28″ suitcases include a 2.0″ (5 cm) expansion zipper that increases depth by approximately 15% when needed. The Carry‑on and Tote do not expand to maintain carry compliance and sleek profile.

Can the bags be nested for storage?

Absolutely. The telescopic handles fully retract, and the soft shells allow each smaller case to slide inside the next size up. When nested, the entire set occupies roughly the footprint of the largest 28‑inch suitcase, saving valuable closet space.

Engineered advantages over conventional luggage

Weight savings: Up to 22% lighter than comparable hardshell sets, preserving more of your airline weight allowance for belongings.

Flexible capacity: Soft shell construction allows slight overpacking without risking cracks, unlike rigid polycarbonate cases.

Acoustic comfort: Proprietary TPU wheel compound operates at < 55 dB, measurably quieter than standard luggage wheels.

Modular organization: Four pieces create a cohesive system; use the tote as a day bag or attach it to the carry‑on for hands‑free movement.

It Works! (Mustang 2016 ecoboost knocking noise)
Style: Modifier
I recently experienced a remarkable transformation in my 2016 Mustang Ecoboost, thanks to the LIQUI MOLY Oil Additive Cera Tec 3721. As someone with a passion for automobiles and a background as a software engineer, I'm always on the lookout for ways to improve my vehicle's performance. This product turned out to be a game-changer. One of the issues I had been facing with my Mustang was a persistent knocking noise, which can be quite concerning for any car enthusiast. After researching potential solutions, I decided to give LIQUI MOLY Cera Tec 3721 a try. And I must say, I was pleasantly surprised by the results. The primary reason I opted for this oil additive was its promise of ceramic wear and tear protection. As someone who values the longevity of my vehicles, I wanted to reduce engine friction and wear as much as possible. This product did exactly that. The moment I started using it, I noticed a significant reduction in engine noise, especially the knocking sound that had been bothering me. It provided a smoother engine performance, and the difference was noticeable. What impressed me even more was the impact on fuel consumption. As someone who loves to travel and has explored six states during my time in the USA, fuel efficiency is a key concern. LIQUI MOLY Cera Tec 3721 not only improved my engine's performance but also led to lower fuel consumption. This means fewer stops at the gas station and more miles of adventure. Moreover, being a mentor and research assistant, I appreciate the science behind this product. It's clear that LIQUI MOLY has put considerable effort into developing a high-quality additive that benefits both petrol and diesel engines. This is the kind of innovation that I believe will shape the future of the automotive industry. In conclusion, LIQUI MOLY Oil Additive Cera Tec 3721 has not only fixed the knocking noise in my Mustang but has also enhanced its overall performance. It's a product that aligns with my goal of staying at the forefront of technology and innovation in the IT sector, even when it comes to my car. I highly recommend it to anyone looking to improve engine performance, reduce friction, and achieve better fuel efficiency. It's a small investment with significant returns for your vehicle.

Skeptical...... to Believer
Style: Modifier, Style: Modifier
I've waited awhile to write this review, to see how time effected my opinion. A little background, my daughter really wanted a 328i, so I went out and found a clean, single owner vehicle with a little over 100k on it. Its the family's first BMW, but as a mechanic I've seen and worked on them all. The BMW N52 engine seems overly complicated for what it does. Power output and economy are just average even though its got just about every bell and whistle including variable valve timing. One thing that struck me was how noisy it was. Kinda like a quiet sewing machine. I changed the oil to Mobil 1 0w/40 Euro blend and she drove it for 7k miles. During this time I read up on all the LL/01 oils for this car, so next oil change I used Castrol Edge, which is LL/01 certified. No difference. Car runs well, still sounds like a sewing machine. 7k more miles go by, and I learn about this CeraTec additive, and decide to give it a try based on all the good reviews. Yup, looks like a Orange Julius!! Well, I dump it it, and take it around the block. Engine seems a little quieter and smoother, but figure its my brain screwing with me. I slam the hood, and give my daughter the keys back, and off she goes. And here's where it gets interesting.... My 19 year old daughter doesnt know squat about cars. She a 100% gas it up and go girl. So about 2 weeks after the CeraTec goes in we are sitting at the dinner table and she says... " Oh Daddy, I forgot to thank you for tuning up my car". I ask her what makes her think I did? She replies that since the last service its much smoother idling at red lights and its quieter. (Remember, she's driven it for 7500 miles at this point) I asked her how could she tell, as the radio is always at least half volume. She says when its running and she's got the window down ordering at a drive -thru it used to go "tickity-tickity" ( her words)as it echo'ed off the building.. and now its silent. I go out and fire it up and roll down the window and stick my head out.... yup. Silent and verrry smooth. She also has average MPG constantly on display , and its improved about .65 mpg. So, if you add all that up, it seems to work. Liqui-Moly says its lasts 30k miles. I service the car every 7k, so we'll see if this all stays the same after a service, which is coming up soon. The car uses zero oil between services, so I cant comment on that. But from a smoothness, quietness point of view, if my daughter noticed it without me prompting her, I would say thats what made me a believer more than anything. Thanks Liqui-Moly.

My 2018 Mustang GT BBQ Tick went away but came back.
Style: Modifier
Update 1-26-2019: The BBQ/Typewriter tick came back this morning. So, I'd say that if you're trying to use the Ceratec to quiet the tick, it will work for a little while, but will eventually return. I don't think there's anything else that can be done to quiet the tick and it's a crap shoot if you get it serviced. In my case, it only ticks during warm up after the transition from high idle, and goes away completely once the entire engine is fully warmed up, so I'm just going to live with it. I'm still giving the Ceratec a 5 because it did reduce my friction enough for a small MPG improvement, so I believe it works as advertised and I'm not going to blame them for not silencing the tick. Update 1-20-2019: After a few days with only the one bottle poured in, my tick came back. Since one bottle is only 1/2 the recommended concentration for the 10 quarts in a 2018 Mustang GT, I bought another bottle and added it and the tick is now gone again. We'll see if it lasts. I can tell you that my fuel economy has improved. I have a little over 11,000 miles now and I always display my fuel economy meter and I use it. I've never reset my average fuel economy meter since the day I bought the car new. I've been pretty well stuck at 21.6 MPG for the last couple months. Since I've put in the Ceratec, my average fuel economy has increased to 21.8 MPG, so it's jumped 0.2 MPG in roughly 2 weeks. With over 11,000 miles included in the average, it takes a pretty significant improvement in friction to make that average move that much in that short a time. Even if my tick comes back again, I'm sold on Ceratec for the friction reduction alone. I'll update the review again if the tick comes back. Original Review: My 2018 Mustang GT developed the infamous BBQ/Typewriter tick immedaitely after my first oil change. I used Mobil One synthetic at 3500 miles on my first oil change. I did my 2nd oil change at 10K miles with Mobile One, but the tick was still present. After seeing people on YouTube having success eliminating their tick with Ceratec and after reading the one other review of a 2018 Mustang GT owner here on Amazon, I decided to try it. I ordered 1 bottle. It arrived on a Friday and poured it in immediately after I got home from work. It's an hour drive one way to work, so the engine was at operating temperature, where, in my case, the tick goes away. I only get it when the engine switches from high idle to normal idle after a cold start and the tick is quite loud for at least the 15 minutes it takes for me to get to the drive through where I get my morning coffee, where I can really hear the tick echoing off the wall. After pouring it in, I started the car and let it idle, but didn't really notice any change. I then took it for a drive and did some hard pulls to get the engine to rev under load to the red line. After that, I put the car in the garage until I drove to work on Monday. When I went to the drive through to get my morning coffee, there was no tick! It was gone! I listened real hard, but all I could hear was the normal direct injector pump noise. Then, after my hour long drive to work, I left car running and got out to listen. With the hood closed, it was quieter than at any time since I bought it. It was virtually silent. Even the DI pump noise was barely audible. The car also sounded and felt different during the drive to work. The engine seemed like it was smoother somehow. It might have been my imagination, but after the silence in my parking spot at work, I wouldn't be surprised if the engine did run smoother. At any rate, I only used 1 bottle to treat the 10 quarts of oil, which is half the amount the mfg says to use. So, I'll see how long it lasts, but it definitely worked even at half its normal concentration. I highly recommend it for anyone who has the 2018 Mustang GT tick.
