Best Lightweight Cabin Suitcases: Ranked by Weight

Most people shopping for the best lightweight suitcase in the UK go straight to the weight on the spec sheet, which is fair enough. But the number alone doesn’t tell you why two cases that look identical can weigh completely different amounts, or which one is going to hold up to how you travel. The answer to both questions is the same thing: the shell material.

Here are five Lugg cabin suitcases ranked by weight, from lightest to heaviest, with an honest explanation of what each material means in practice.

All five are 20-inch cabin suitcases sized for UK airline overhead lockers. If you need a lightweight medium or large suitcase for checked luggage, the same material principles apply across the full Lugg range.

Why Shell Material Determines Suitcase Weight

Hard shell suitcases are made from a small shortlist of materials. ABS (acrylonitrile butadiene styrene) is the lightest practical hard shell material for everyday travel, light enough to keep your allowance working for you, strong enough to handle the hold and the overhead locker without issue. It is the material the majority of UK lightweight cabin suitcases are built from, and it is the most affordable of the hard shell options. It protects your belongings well and it's more than good enough for most UK travellers who fly once or twice a year. It is more likely to crack under heavy impact than polycarbonate, which is worth knowing if you check bags frequently or travel a lot. Polycarbonate is slightly heavier at cabin size but it flexes under impact rather than cracking, which is why it's the more durable option for frequent flyers. A polycarbonate coating on top of an ABS base splits the difference: you keep most of the weight savings and pick up improved scratch resistance. Aluminium is the premium end of the market, the heaviest and the most structured, built for a different brief from the others entirely.

At cabin size, the weight gap between ABS and polycarbonate is smaller than most people expect. In the range below, it’s 300 grams. Whether that matters depends on how close to the limit you’re packing. Not sure whether hard shell is right for you at all? Read our hard shell vs soft shell guide before you decide.

1. Jetset Cabin Suitcase: ABS hard shell, 2.5 kg

The lightest hard shell cabin suitcase in the Lugg range. Pure ABS construction, which is why it lands at 2.5 kg. It measures 55 x 35 x 23 cm and works as standard cabin luggage on British Airways, Jet2, Aer Lingus, Air France, Lufthansa, KLM, Virgin Atlantic, Turkish Airlines, Delta, Etihad, Finnair, Swiss, Eurowings and Norwegian. Compatible with easyJet Plus and Wizz Priority too. TSA lock, 360 degree spinner wheels, water-resistant coating.

Sage Green is one of the newer colourways, alongside Stone and Slate Blue. If keeping the suitcase weight low is the priority and you fly a handful of times a year rather than constantly, the Jetset is the one to start with. 

The one to reach for when the scales matter most: Jetset Cabin Suitcase in Sage Green. Weighs 2.5 kg and comes in Sage Green, Stone and Slate Blue as part of the new 2026 colour range.
 

2. Sky Rover Cabin Suitcase: ABS with Polycarbonate Coating, 2.6 kg

One hundred grams more than the Jetset, with one meaningful difference in the construction. The Sky Rover uses an ABS base with a polycarbonate coating, which improves scratch resistance without adding much weight. The ribbed panel design helps the shell hold its shape under pressure too, which is useful in a packed overhead locker. Same dimensions as the Jetset at 55 x 35 x 23 cm and the same core airline list, with Ryanair Priority added. TSA lock, 360 degree spinners.

If you want the lightness of ABS with a more durable finish, the Sky Rover lands well between the two. 

Lighter than it looks, tougher than it needs to be: Sky Rover Cabin Suitcase in Amethyst. Weighs 2.6 kg and is available in eight colourways including Oxblood, Amethyst and Army Green.

3. Vacay Cabin Suitcase: ABS Hard Shell, 2.7 kg

Same ABS hard shell as the Jetset, 200 grams more. The weight difference at this material comes down to the shell geometry and interior components rather than a different material choice. The Vacay has a TSA indent lock rather than a standard combination lock and 360 degree double spinner wheels, both of which add a little. Same 55 x 35 x 23 cm footprint, same airline compatibility as the Jetset with Wizz Priority included.

Stone is a neutral colourway that works as well for a work trip as a weekend away without looking like it’s trying too hard at either. A solid option if you want ABS weight with a more considered finish. 

Same weight class as the Jetset with a step up in finish: Vacay Cabin Suitcase in Stone. Weighs 2.7 kg and is available in Stone, Terra Cotta, Hazy, Slate Blue, Sage Green and Army Green.

4. Air Glide Cabin Suitcase: Polycarbonate Hard Shell, 2.8 kg

The lightest polycarbonate cabin suitcase in the range. At 2.8 kg it’s only 300 grams heavier than the Jetset, which is less of a gap than most people expect when comparing ABS and polycarbonate at this size. What you get for those 300 grams is a shell that flexes under impact rather than cracking, better scratch resistance over time and the Air Glide’s detachable interior, which hangs directly in a wardrobe or hotel closet rather than requiring a full unpack. Five-year warranty included.

The dimensions are 55 x 38 x 23 cm, slightly wider than the three cases above, which explains some of the weight difference and gives a little more interior room. TSA lock, ultra-smooth 360 degree spinners.

If you fly more than a couple of times a year and want a lightweight hard shell cabin suitcase that holds up over repeat use, the Air Glide is the one to go for.

The case that earns its extra 300 grams: Air Glide Cabin Suitcase in Ivory. Weighs 2.8 kg and comes with a five-year warranty as standard.

5. Solo Explorer Hard Shell Suitcase: Polycarbonate with Aluminium Frame, 3.7 kg

The heaviest in the five, and built to a completely different brief from the others. The Solo Explorer’s weight comes from its aluminium frame, not the polycarbonate shell but the structural skeleton around it. That frame is what makes it 900 grams heavier than the Air Glide, and it’s what enables the zip-free closure and dual TSA locks rather than one. This is not a lightweight cabin suitcase in the conventional sense. It’s a structured, secure case that happens to be cabin-sized.

For what the extra weight costs you, you get a zip-free aluminium closure that’s significantly harder to breach than a standard zip, dual TSA-approved locks, 37 litres of organised interior with dual compartments, zipped dividers and compression straps on both sides, and 360 degree spinner wheels. Dimensions are 55 x 38 x 22 cm.

If the scales are your priority for cabin travel, the Solo Explorer isn’t the answer. If security and build quality matter more than the weight, it sits in a different category from the other four entirely.

A suitcase built to last: Solo Explorer Hard Shell Suitcase in Metallic Silver. Weighs 3.7 kg and is available in Metallic Silver, Gold and Champagne.
