Packing, especially for a dive trip, can feel like a daunting mission. It’s particularly challenging when you own all your gear and are heading to those beautiful, often remote, dive destinations where hefty luggage fees are common. It’s a constant battle against airline weight limits and baggage allowances. As a fellow diver and engineer who loves lists, I get it! This guide breaks down my personal packing strategy for a single-tank wetsuit dive trip, aiming to make your next adventure a little smoother.
The Ever-Present Packing Challenge: Weight!
Fitting all your precious dive gear into a strict airline weight and size allowance is a true test of planning. Because the top destinations are often remote, airlines frequently impose stringent weight and size rules on luggage. Most airlines typically cap a single checked bag at around 20-23 kg (44-50 lbs) before charging overweight fees.
Carry-on allowances are even stricter, usually around 7kg (15 lbs). While US airlines are generally more relaxed about weighing carry-ons, European and Asian carriers (especially budget ones) are notoriously vigilant—some would even weigh your carry-on at check-in and again at the boarding gate! You’re also typically (but not always!) allowed one personal item that fits underneath the seat
Check the restrictions of all airlines for your entire trip, and pack for the most restrictive one. This way, you only stress about it once.
My Carry-On & Personal Item Strategy: Survival & Valuables
My philosophy for carry-on and personal items is threefold: (1) comply with airline regulations, (2) protect small, expensive items, and (3) ensure I can still dive (or at least survive) if my checked luggage gets delayed.
Must-Have Onboard: Batteries & Photo Gear
Airline regulations require all batteries (for dive lights, cameras, phones, laptops) to be carried in your carry-on luggage or personal item. Some airlines even require you to tape/cap electrodes and store them in your personal item, placed under the seat. If you have a canister light with big batteries (high Watt-hours), always check directly with the airline to confirm whether those are allowed. I now pack all loose batteries in my personal item so I don’t have to worry about them.
If you’re traveling with underwater photography gear, keep it in your carry-on to protect it. I’m not a serious photographer (yet – just a GoPro for now!), but my dive buddy Kevin’s Olympus TG7 with underwater housing, wide-angle lens, light, and frame takes up significant space and weight. However, I’ve heard that some airlines are more relaxed on weight if they see your bags are filled primarily with photography gear.
Dive Essentials: Computer, Compass, & Mask
- Dive Computer & Transmitter: These are definitely in my carry-on. Dive computers are essential for safe diving, and having your own means you will know all the ins and outs of the computer. Honestly, this is the first piece of gear I’d advise anyone to buy right after certification. My computer has a matching air-integrated transmitter. I always remove the transmitter from the regulator, put the LP cap back on, and carry it with me.
- Mask: I’ve debated this. My instinct says to carry my prescription mask onboard so I can still dive with rental gear if my luggage goes astray. In practice, however, I rarely find space in my backpack for it.

Regulators: Carry-On or Checked?
This is a common dilemma, and opinion is split. Personally, I don’t see the point in carrying my regulators onboard, since it’s pretty difficult to protect them effectively in a small carry-on or backpack. With my long-hose configuration (a 7-foot primary!), it’s even harder to fit onboard.
If you do decide to carry regulators onboard, I’d suggest getting a padded regulator bag or sandwiching them with clothing. Do note that regulators in X-ray scans can look “funky,” so sometimes the security agent at the airport might want to open your bag for inspection.

Personal Survival Kit: Clothing & Medicine
In case of flight delays or lost luggage, I always pack one set of swimwear and one set of daily wear in my carry-on, with essential medicines. I travel in joggers and a zip-up hoodie (airports are notoriously cold!), but some destinations are very warm, so this lets me change right away for the sun. I’m a big fan of Merino wool clothing (more on that another day!) – just one extra set can get me through many days. The way I pack typically leaves space and weight in my carry-on for all my clothing for the trip.
Checked Luggage: Maxing Out the Allowance (~19kg)
Everything else goes into my checked bag. Some divers impressively manage to fit all their gear into a carry-on, and I applaud them! But as someone who’s always cold in the water, I wear a 5mm wetsuit (or even a drysuit, depending on the destination) almost anywhere, making it impossible to fit all the gears into a single carry-on.
Bag Choices & Smarter Packing
- Hard-shell Suitcase: I use a normal 26-inch hard-shell suitcase for my gear. Scuba-branded bags often scream “expensive gear inside!” and might attract unnecessary attention.
- IKEA Bag: Always, ALWAYS bring an IKEA bag! It’s incredibly robust and functional, perfect for transporting gear if needed (e.g., from your hotel room to the dive shop). It’s much smaller than a typical gear bag. I’ve often left one (they come in a few different colors, with the cheapest at $1!) with dive professionals as a cheap, practical souvenir.

Regulators: Protect by BCD or Wetsuit
If checking in the regulators, I put my regulator(s) in a vacuum bag (not for vacuuming, but simply for organizing the hoses) and sandwich them securely between my wetsuit or wing (I dive backplate and wing, but you can use your BCD in a similar protective embrace) in my checked luggage. This way, even if TSA opens the bag, the regulators are unlikely to spread out, cause confusion, or entangle with other items.
Fins & BCD: Personal Preference vs. Travel-Specific Gear
Some divers opt for specific travel-friendly BCDs and fins. For me, I stick with my regular gear. My backplate and wings are already quite minimal and easy to disassemble for packing. My checked-in luggage has two almost equal compartments, so I typically put my BCD + Regulator + Wetsuit in one side and fins on the other. Then I fill in all the smaller items.
My current wetsuit fins are Scubapro Go Sport fins. They’re a tech-style fin—shorter, lighter, and positively buoyant, making them very travel-friendly. I pack my fins along the sides of my suitcase to maximize space. However, I find them a bit lacking in currents, making me work harder to keep up. I’m looking to switch to Dive Rite XT fins, which will add about 1kg to my luggage – luckily, I have that kilo to spare!
Some people prefer longer blade fins or freediving fins. You might need to cross the fins to fit them in the suitcase, or choose a suitcase with larger dimensions. Typically, freediving fins come with their own case, or can be disassembled into foot pockets and blades for easy packing.

Mask: Multi-functional Mask Box
Since now I mostly put my mask in the checked luggage, I always carry it in my mask box. It’s almost waterproof when closed, perfect for storing my glasses while gearing up. After the dive, my dive computer and compass go inside, protecting them from knocks in the crate. I also fill the box with some clothing to save space and provide padding for my mask. It might seem big, but worth it in my opinion!
I used to think dive gear was really fragile, but I’ve learned that it’s surprisingly ROBUST – certainly more so than I initially thought!
Pro Tips for Packing Like a Pro
Check Airline Restrictions: Research the weight, size, and baggage policies for every airline on your trip. Pack for the most restrictive carrier to avoid issues.
Don’t Overthink Fragility: Dive gear is often more robust than it seems. Focus on protecting small, fragile, and important items like regulators, dive computers, and transmitters, and rely on the durability of the rest of your equipment.
Keep Essentials Accessible: Always carry the minimum you need to dive in your carry-on. This includes your mask, dive computer, and a change of clothes (swimsuits and street clothes).
