A travel diary · MEL T4, last Friday

The 24 minutes you'll never get back.

Carousel four. 7:14pm. Every Jetstar flight, the same theatre. Then there are the people who walked off the plane and into their Uber. They had a Nexy. So can you.

Sarah Hennessy boarded JQ501 at Gate 47 last Friday, and she got off twenty-four minutes before her friend Kate did. Same flight. Same arrival time. Sarah walked straight through the sliding doors and into her waiting Uber. Kate stood at Carousel 4 watching other people's bags go round.

"I used to think people who didn't check a bag were just bad packers," Sarah told me at a café in Brunswick two weeks ago. "Turns out they were just better at maths than me."

The maths, when you do it, is brutal. A Jetstar Starter fare from Melbourne to the Gold Coast: $89. A checked bag, pre-paid: $35. At the gate when it doesn't fit your carry-on: $65. Multiply by two for the return. Multiply by however many flights you take in a year. Three trips a year and you've spent more on paying to bring your own clothes with you than most people spend on a decent suitcase.

Watch a week of clothes compress in 18 seconds.

Filmed in a Melbourne flat. No edits, no time-cuts. Seven shirts, two pairs of jeans, a hoodie, six pairs of socks, a toiletry bag, a charger, a notebook, and a pair of runners. Start weight: 5.8kg. Final volume: 18 litres.

7 days of clothes → 18L of compressed bag → 56×36×23cm carry-on. Tested on JQ503 last week.

How it actually works

It's not magic. It's a valve and a shape.

Sharp question, first: compression doesn't shave a gram off your 7kg. Anyone telling you it does is selling you snake oil. What it does do is stop the gate agent from glaring at your bulging duffel.

The fee that gets most people isn't the weight one — it's the $65 sizer fee when your bag is 24cm deep instead of 23. Nexy's structural shell is built to 56 × 36 × 23cm including straps and handles, and the compression valve locks contents inside that envelope no matter how full you load it.

Empty, the bag is 1.1kg. That's 1.8kg lighter than the average Australian hardshell carry-on, which means 1.8kg more of your kit comes with you under the same Jetstar 7kg cap. Six cotton t-shirts. A puffer. A pair of merino trousers.

Compliance · verified May 2026

Built to the published cap of every major Australian carrier.

Carry-on rules tightened in early 2026. Virgin Australia moved to a single 8kg bag on 2 February 2026. Bonza is gone. Rex's capital-city operations collapsed. Jetstar's 7kg cap is being more strictly enforced than at any point in the airline's history. The Nexy is built to fit all of it.

Compression shrinks the contents, not the kilos. But it's the bag's shape — not just the weight — that gets you flagged at the gate. — from the design notebook, James Wren, founder

James Wren

Founder · Nexy · Melbourne

I built the first Nexy because I got slugged $65 at MEL T4 in 2022 for a carry-on that was three centimetres too tall, and decided that was the last time. We're designed in Brunswick, assembled overseas so the price can stay at $125 instead of $325.

We don't carry the Australian Made kangaroo — the safe harbour rules require substantial transformation in Australia, and ours happens overseas. The full bill of materials is here.

The five questions every buyer asks

Common questions, honest answers.

Comment-mined from 12 months of Meta ads, ProductReview.com.au, and r/onebag threads. Ordered by frequency.

"Isn't 1.1kg heavy for an empty bag?"

Fair point — at 1.1kg empty, Nexy is heavier than a flimsy nylon duffel. But on Jetstar's 7kg Starter allowance, Nexy gives you 5.9kg of usable payload — within 80 grams of an Antler Soft Stripe and 1.4kg ahead of the July Carry-On Light. The extra weight buys you a compression valve, YKK Aqua zips, and a frame that holds shape under a sizer cage. Lighter bags exist. They don't survive their second flight.

"Doesn't vacuum compression just put more weight in the same space?"

Yes — and that's the honest answer. Compression doesn't shave a gram off your 7kg. What it does is stop the gate agent from glaring at a bulging duffel. The fee that gets people isn't the weight one — it's the $65 sizer fee when your bag is 24cm deep instead of 23. Nexy holds its shape because compression locks the depth at exactly 23cm.

"What if the pump dies overseas?"

It charges via USB-C in about 90 minutes and holds 8 full pump cycles on a single charge. If it dies anyway, the bag has a manual release valve and your clothes are still inside — nothing is sealed shut. The pump is covered under our 2-year warranty.

"Will my clothes come out wrinkled?"

Less than they would in any other carry-on, because compression eliminates the in-bag shuffling that creates most wrinkles. Roll your clothes before you compress — same as you would for a suitcase — and a quick steam at the hotel sorts everything out. Merino doesn't wrinkle at all.

"$125 vs the $39 Kmart special — what am I paying for?"

A 4mm one-way compression valve from a German supplier. YKK Aqua-resistant zips. Recycled 600D shell that's been tested against the Jetstar metal sizer cage 300 times without deformation. A 2-year manufacturer warranty plus lifetime cover on the compression mechanism. The $39 Kmart bag doesn't have any of those, and it's not designed to be re-used for five years of weekly travel. The maths still works in our favour.

"I did the maths after my third Bali trip. The bag had paid itself off twice." — Sam K., Newtown NSW · ProductReview.com.au · ⭐⭐⭐⭐⭐

Order & shipping

Logistics, quickly.

How long does AU shipping take?

Most orders ship from our Sydney warehouse within 24 hours. Metro deliveries arrive in 2–3 business days. Regional NSW, VIC, QLD, SA, WA typically 4–6 days. NT and remote: 7–10 days.

How does the 60-day trial work?

Take the bag on a real trip. If after 60 days you'd rather not keep it, email us at support@trynexy.com and we'll send a free return label. Refund processed within 5 business days.

What's the warranty?

Two-year manufacturer's warranty on the bag and pump. Lifetime cover on the compression valve mechanism.

Can the pump go through airport security?

Yes — wireless pump is a sealed lithium-ion device with an integrated USB-C charger, equivalent to a phone power bank.

Does it fit Rex Regional turboprops?

Rex Saab 340s have a tighter 48×34×23cm cabin allowance. We recommend gate-checking on Rex regional services — it's free and the bag is built to survive handling.
