An honest answer to one question

Why is this $125?

Compact yet capable. Engineered, not sourced. A carry-on that compresses six days of merino into Virgin's 8kg cap — and weighs 1.1kg empty doing it. Designed in Melbourne. Assembled where it makes sense.

The first time you handle a Nexy, the question presents itself before anyone asks it. You pick it up, expecting the heft of a usual carry-on, and find one-point-one kilograms. You open the main compartment, expecting the cheap rustle of polyester, and find a recycled 600D ripstop with a hand. You see the valve — small, brass-coloured, recessed — and the question becomes the only one worth asking.

Why is this $125?

The honest answer is that we don't have a kangaroo logo and we don't own a Melbourne factory. We have a designer in Brunswick, a manufacturing partner in Vietnam who's been making bags for thirty years, and a warehouse run by a couple who went to RMIT with the founder. The price is what's left when you skip the bits that don't make a bag better.

A week of clothes. Eighteen seconds.

Filmed in a Brunswick flat, single take. Seven shirts, two trousers, a knit, six pairs of socks, toiletries, a charger, a notebook, runners. Total: 5.8kg. Final volume: 18 litres.

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

The bag is the lightest carry-on I've owned, and the only one I've never wanted to replace within a year. — Joanne L., Toorak VIC · 21-day Italian trip, April 2026

How it actually works

A valve, a shape, and three honest constraints.

Compression does not reduce weight. The 7kg you pack is the 7kg you carry, and any brand telling you otherwise is selling a sleight of hand. What compression does is hold the bag's outer dimensions to the published 56 × 36 × 23 centimetres, no matter how full the bag is. It's a shape guarantee, not a weight guarantee.

At 1.1kg empty — light by every category benchmark we've measured the Nexy against — the bag returns 5.9kg of usable payload under Jetstar's 7kg cap. Six cotton shirts, a knit, merino trousers, and toiletries. Three days of clothing more than the average Australian hardshell at the same weight cap.

The valve itself is sourced from a German supplier we found through a maritime equipment catalogue. The zips are YKK Aqua. The shell is recycled, the lining is OEKO-TEX certified, and every piece is named on the bill of materials page.

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. Jetstar's 7kg cap is enforced more strictly than at any point in the airline's history. The Nexy is built to fit all of it.

Airline	Max size	Max weight	Nexy fit
Jetstar Starter	56×36×23	7kg	✓ Exact
Virgin Australia (from 2 Feb 2026)	56×36×23	8kg	✓ Exact
Qantas Domestic	56×36×23	10kg	✓ Exact
Rex Regional (Saab 340)	48×34×23	7kg	⚠ Tight

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.

Five questions, considered

Common questions, honest answers.

Drawn from twelve months of customer correspondence and the ProductReview.com.au thread. Ordered by frequency.

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

A fair question. At 1.1kg empty, Nexy is heavier than a flimsy nylon duffel and lighter than most structured carry-ons in the category. On Jetstar's 7kg Starter allowance, the bag returns 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 grams buy a compression valve, YKK Aqua zips, and a frame that holds shape under a sizer cage. Lighter bags exist. They do not generally survive their second flight.

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

Yes. Compression does not shave a gram off the seven kilograms in your bag, and we have no interest in pretending otherwise. What it does is prevent the bulge that gets your bag pulled aside at the sizer cage. The fee that catches most travellers isn't the weight one — it's the $65 gate fee when a soft bag is 24cm deep instead of 23. Nexy holds its shape because compression locks the depth.

"What if the pump dies overseas?"

The wireless pump charges via USB-C in approximately ninety minutes and holds eight full pump cycles per charge. If it dies anyway, the bag has a manual release valve and your clothes remain accessible — nothing is sealed shut. The pump is covered under our two-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. Rolled merino emerges almost unmarked. Linen will require steaming, as it would from any suitcase. The trade-off favours compression in nearly every case we've tested.

"$125 against the $39 alternative — what am I paying for?"

A 4mm one-way compression valve from a German supplier. YKK Aqua-resistant zips. A recycled 600D shell that's been tested against the Jetstar metal sizer cage three hundred times without deformation. A two-year manufacturer warranty plus lifetime cover on the compression mechanism. The bag is designed to be your only carry-on for the next five years, not the next five flights.

"It's the only bag I've ever bought that didn't need replacing the year after." — Andrew P., Albert Park VIC · ProductReview.com.au · ⭐⭐⭐⭐⭐

Order & shipping

Logistics, briefly.

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 support@trynexy.com and we'll send a free return label. Refund processed within 5 business days. This trial is additional to your rights under Australian Consumer Law.

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. The 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.
