Costa Rica Travel Packing List: The Gear That Earned Its Spot

Introduction

A family visit to Costa Rica’s southwest coast near Manuel Antonio came with an unusual constraint: personal-item-only flights, with an 18 x 14 x 8 inch bag limit that had to fit under the seat. That shaped every packing decision on this list. Everything here had to justify its size and weight, and most of it did. If you are planning a warm-weather, one-bag trip to Costa Rica or somewhere similar, this is the gear that earned its spot.

The Main Bag: GORUCK GR2

The GORUCK GR2 measured 18 x 12.5 x 7.25 inches, comfortably smaller than the allowed personal-item size. It fit easily in the airline’s sizer box at the gate, slid under the seat, and still worked in the overhead when the flight was light. Fully packed, it weighed about 14.3 lb (6.5 kg).

The organization is the standout. A large front pocket gives quick access from outside the bag, surrounded by small zip pockets and dividers that hold almost all your small gear without opening the main compartment. A stretchy sleeve on the inside back is perfect for thin items like sandals, and the lay-flat clamshell main compartment makes packing genuinely simple. Top pockets work well for dirty clothes or miscellaneous items. It is bulkier and pricier than many travel bags, but it is extremely well built and surprisingly pleasant to live with for a week.

A few practical notes from the airline itself: there was a sizer box at every gate, though nobody was actually checked, and nothing is complimentary on board, so pack plenty of snacks and water.

Day Pack and Organization

With the main bag sorted, a few smaller pieces kept everything organized in transit and usable day to day.

Tortuga Packable Day Pack

The Tortuga Packable Day Pack handled daily duty beautifully. It folds nearly completely flat when empty, so it takes up almost no room in the main bag, yet it carries everything you need for a day out. It was not yet released at the time of this trip, but it performed very well in real use.

Eagle Creek Medium Compression Cube

The Eagle Creek Medium Compression Cube is one of the best compression cubes around, squishing clothes down so they fit far more easily in the bag. Compared with a more rectangular alternative, it runs a little longer and skinnier, which suited the small clothing load here.

Clothing and Footwear

The coast is hot, and with sweating, showering, and changing clothes multiple times a day, lightweight clothing that washes and dries easily matters more than quantity. Having access to a washing machine for part of the trip allowed a much smaller clothing load: three t-shirts, three pairs of underwear, and one pair of socks beyond what was worn on the plane.

Western Rise Evolution Shorts

The Western Rise Evolution Shorts worked great, and a drawstring means they double as swim trunks. Two pairs covered the whole week. The matching Evolution Pants were worn on the plane as part of a wear-your-heaviest-items strategy that offsets everything packed.

Zero Z Trail EV Sandals

One pair of minimalist sandals, the Zero Z Trail EV, packed small and covered beach, town, and casual wear. They slipped easily into the GR2’s interior stretchy sleeve.

Merrell Vapor Glove Barefoot Shoes

An older pair of Merrell Vapor Glove barefoot shoes handled anything beyond sandal territory. They were worn on the plane and packed down small enough to swap back and forth with the sandals without eating pack space.

Electronics

Electronics were deliberately minimal: no laptop, but an e-reader, phone, battery pack, and charge cord. Costa Rica uses the same plugs as North America, so an adapter was not strictly necessary, but a good multi-port charger still earns its place when several people share one outlet.

Google Pixel Buds Pro

The Google Pixel Buds Pro with noise cancelling have been in daily use for three months and still impress. They were a natural pick for flights and downtime.

iClever 70W Travel Adapter

The 70W iClever travel adapter offers five ports, which makes it ideal for travel, especially with multiple people sharing. Even where no plug adapter is needed, it consolidates charging into one compact unit.

AirFly Pro

The AirFly Pro connects in-seat entertainment systems to wireless earbuds. In this case none of the flights had televisions, so it went unused, but it remains a smart addition for airlines that still rely on wired seat-back audio.

Utility Gear: Stands, Ties, and Lights

Two new pieces were tested specifically for airplane use, and a small flashlight quietly became one of the most useful items on the trip.

iFlex Phone Stand

The iFlex is essentially a piece of metal with a thick rubber coating. Folded into a seat-back pocket, it works great as a phone holder. The only real drawback is that it is a little bulky for an already tight personal-item setup.

Nite Ize Gear Tie

The Nite Ize Gear Tie, a large bendable twist tie, worked almost as well as the iFlex as a phone stand while taking up far less space and weight. It also proved far more versatile: tie gear to the outside of a pack, secure loose items, or prop a phone on any flat surface. Of the two, this is the one that kept earning its spot.

Pocket Flashlight and Travel Monoculars

A small pocket flashlight with a UV mode was incredibly helpful on a night bat tour, and the UV light doubles as a scorpion detector, a genuinely useful feature in areas where scorpions are active at night. For nature viewing, a compact pair of Zeiss monoculars came along. Bought for a Galapagos trip a few years ago, they fold down into a tiny package, and with bird watching in Costa Rica being amazing, they were definitely needed. They are expensive, but the optical quality in such a small form factor is hard to beat.

Toiletries and Small Essentials

The toiletry setup was as minimalist as possible, plus a handful of small items that punch well above their weight.

Eagle Creek Extra Small Toiletry Bag

The Eagle Creek Extra Small Toiletry Bag is the smallest one on hand and held a deliberately basic kit: solid shampoo bar, soap bag, razor, folding toothbrush, mini mirror, and a foldable ten-compartment pill container that carries small amounts of multiple pills, with pharmacy top-ups available at your destination if needed.

Chums Surf Short Wallet

The Chums Surf Short Wallet handled money, passport, travel documents, and receipts, usually kept in the bag or on the person. Two pockets, a divider, a clear window, and a key ring make it genuinely useful, and looping a small cord around a belt means there is no worry about losing it.

Matador NanDry Towel

The Matador NanDry towel barely dries you off, but it packs down to almost nothing. It also does double duty on hikes: get it wet, wrap it around your neck to stay cool, or tuck it into a hat as a sun shade.

Nite Ize MicroLock and Security Extras

The Nite Ize MicroLock is a low-key way to add a little extra security, locking zippers together with a small clip that keeps the gates from opening without drawing attention. Sunglasses in a small zip case, a pen and pencil, a sleep mask, a reusable bag for food storage, and mini binder clips for securing chip bags rounded out the miscellaneous drawer.

Final Packing Notes and Buying Advice

A reusable water bottle is worth bringing even if you can borrow one on arrival: Costa Rica is working to eliminate single-use plastics, and some national parks will not allow them in. A small bag hook, similar in spirit to a Heroclip but a little easier to use and more low-key, hangs your bag on tables or bathroom stall hooks.

For packing strategy, plan where everything goes before you start. The GR2 rewards this: small gear lives in the front compartment for outside access, sandals in the interior sleeve, the compression cube in the main compartment, and an electronics pouch on top for easy access on the plane, whether the bag goes under the seat or in the overhead.

As for how it all performed over the week: three t-shirts and two pairs of shorts worked well with a mid-trip laundry run, and a poncho brought “just in case” turned out to be genuinely useful on a rainy cloud forest trip to Monteverde, where it rains almost constantly even in dry season. If you can pack small enough to fit in the GR2 and accept the price tag, it is an extremely well-built and useful travel backpack. Everything else on this list earns its place by being small, light, and multi-purpose, which is exactly what personal-item-only travel demands.

Conclusion

This setup proves you can cover a hot-weather week of travel, hiking, swimming, and flying with a single personal-item-sized bag. Prioritize quick-drying clothing, gear that folds or compresses flat, and small multi-use tools, and you will not miss the larger suitcase at all.
