Carry-On Only Travel Gear That Held Up in Thailand: 8 Products Worth Packing

Introduction

A ten-day trip through Bangkok, Koh Samui and Koh Phangan, flown entirely with carry-on luggage, is a solid real-world test for any piece of travel gear. Heat, humidity, boats, internal flights and long-haul legs all push kit to its limits, and the products that earn a permanent place in the bag are the ones that make travel simpler rather than more complicated.

This roundup covers the eight standouts from that trip: the backpack that carried everything, merino clothing that skipped the laundry cycle, a sling that handled streets and motorbikes, a razor that replaced three heavier ones, surprisingly capable slip-on shoes, a pocket camera, and a pair of earbuds with one important lesson attached.

The Backpack: Matador SEG28

The Matador SEG28 is a 28-litre backpack that weighs just under a kilogram, and that low weight turned out to be a major advantage for carry-on travel. The pack was full on this trip but never packed solid, which left room to move things around as plans changed.

The compartment system is the standout feature. A mix of front pockets combined with a full internal clamshell opening meant direct access to liquids at security, quick retrieval of a cable from a tech pouch mid-flight, and a toothbrush grabbed in the dark without opening the whole pack. The harness was comfortable enough that rushing for a boat or plane never felt like a chore, and the grab handles and compression straps rounded out a genuinely practical feature set. It is hard to think of another pack at this size and weight with a setup this well suited to one-bag travel.

Merino Clothing: Unbound Merino Hoodie and T-Shirts

Unbound Merino focuses purely on 100% merino wool clothing designed for travellers rather than trekkers, and both pieces tried on this trip earned their place.

The Compact Hoodie

The compact hoodie is thin but genuinely warm, comfortable against the skin, and packs down small when not being worn. Worn on the plane, it proved to be close to the ideal travel hoodie: light enough to carry when not needed, warm enough for chilly cabins and cool evenings.

The T-Shirts

The t-shirts are where merino wool really shows what it can do. Merino keeps you cool in heat and warm in the cold, and it is naturally antimicrobial, meaning bacteria cannot act on absorbed sweat, which is what normally causes odor. The real-world test was brutal: worn for around 24 hours on the outbound flights, then a full day in 35-degree heat and heavy humidity without washing, then a night out, an internal flight, another full day, and finally the 24-hour return trip. It dried quickly when sweaty, still looked presentable, and never developed an odor, while cotton t-shirts felt damp and clearly needed washing after a single day.

For lightweight travel, a merino t-shirt means packing less and wearing more, and that is a genuine shift in how much you need to carry.

The Everyday Sling: Bellroy Venture Sling

The Bellroy Venture Sling at 9 litres turned out to be the right size; a smaller 7-litre sling would have been too tight. It was comfortable thanks to a wide shoulder strap, went everywhere from street walks to motorbike rides, and worked perfectly as the under-seat bag on planes.

Two features stand out. The soft stretchy glasses holder keeps sunglasses high up in the bag where they are easy to reach without competing with the bulk of everything else at the bottom. And the double opposite-ended zips, which run across the top from either direction, make every other sling feel awkward by comparison. A secure zip-back pocket held a passport and cash with total confidence.

Grooming: Philips OneBlade

The Philips OneBlade system replaced three much heavier razors in the toiletry kit, saving serious space and weight. The only downside worth noting is that the blade width is small, so shaving a head takes longer than with a full-size razor. Even so, it is an easy recommendation as a dedicated travel grooming tool, with the heavier home kit reserved for quicker daily use.

Footwear: Allbirds Shoes

Bought specifically because they are lightweight and reviewed well for travel, the main concern going in was durability, since they look soft and unstructured. In practice they were brilliant: comfortable straight out of the box, grippy on market wandering and dinner outings, and even worn on the beach where sand shook straight out of the fabric.

The biggest benefit is that they can be worn comfortably without socks, which meant socks were only needed for the flights themselves. That saves space, weight and laundry on any warm-climate trip. They are breathable, dried quickly when damp, never developed an odor, and the insoles even use merino wool. They also went into the washing machine on return and came out looking like new. For anyone who finds flip-flops unsupportive, these are a strong alternative in hot climates.

Cameras and Audio: DJI Pocket Camera and AirPods

DJI Pocket Camera

The DJI Pocket camera lived in the sling for the whole trip, which made it quick to grab for spontaneous footage. Its palm-sized gimbal form factor is exactly what you want when the alternative is pulling out a phone or a larger camera. For anyone filming travel content on the move, having it permanently within arm’s reach makes a real difference to how much you actually capture.

AirPods (3rd Generation)

The AirPods (3rd generation) did their main job well on the plane for watching films, but the trip highlighted one important lesson: these are not noise cancelling, and on a long flight that is a feature you notice missing quickly. If you find in-ear AirPods Pro uncomfortable, it is worth looking for a well-fitting noise cancelling alternative before your next long-haul. For shorter trips and everyday use, they remain a solid, fuss-free choice.

Overall Buying Advice

The common thread across all eight picks is weight saved without capability lost. A sub-kilogram 28-litre pack, clothing that can be worn repeatedly between washes, socks-free footwear and a pocket-sized camera each reduce what you carry while keeping the trip comfortable. Two extra tips from the same trip are worth adopting: an eSIM with unlimited local data cost about $20 for two weeks compared with nearly $9 per day for 500MB from a home carrier, and a multi-currency card like Revolut handled payments and cash withdrawals in Thailand without the usual card fees.

For a one-bag, warm-climate trip, prioritise the backpack and clothing first, then add the sling and grooming kit, and finish with the tech that matches how you actually spend a flight.

Conclusion

Carry-on only travel proved genuinely liberating: straight to the gate, no baggage carousel, and a taxi within minutes of landing. The gear that made it work was not exotic, just carefully chosen: a light and well-organised backpack, merino clothing that shrinks your packing list, a comfortable sling for daily carry, and a few small tools that quietly solved real problems. Choose pieces that reduce weight and laundry, and long trips start to feel a lot simpler.
