Pack one soft-sided bag of up to 40 lb (18 kg) for a river cruise on the Mekong between August and December: quick-dry clothes, shoes with grip, covered shoulders and knees for temples, a rain jacket, and a small medical kit. The vessel supplies slippers, a laundry service, and a marine medical kit, so the bag stays light. Pack for heat, rain, and three shore settings—village paths, small boats, and temples—then fit the bag to what the vessel already holds.
What luggage does a river cruise cabin accept?
Calypso Mekong accepts soft-sided bags only: duffels, canvas bags, and collapsible backpacks, up to 40 lb (18 kg) per person. A soft-sided bag has no rigid frame and flattens when empty. Hard-shell suitcases and rigid-frame bags stay ashore because they cannot flex into curved hull lockers and an empty case blocks a walkway.
| Bag | Accepted | Reason |
|---|---|---|
| Duffel or canvas bag | Yes | Tucks under a berth |
| Collapsible backpack | Yes | Folds flat |
| Hard-shell or rigid-frame bag | No | Cannot flex into lockers |
Follow the lower of 40 lb and your airline’s checked-bag allowance. Carry one outfit, medicines, and chargers in a soft hand bag, so a delayed bag does not leave you without essentials.
What storage does each cabin offer?
Each of the three cabins has an ensuite bathroom, air conditioning, and storage lockers, and soft bags tuck under the berths. The layout follows the Aquila 44 catamaran model; Calypso Mekong will publish measurements of its own cabins after the survey.
| Cabin | Bed | Storage |
|---|---|---|
| Owner’s stateroom, full beam | Queen island berth | Lockers and wardrobes |
| Guest cabins (two) | Queen beds | Lockers |
Is there a dress code on a Mekong river cruise?
No formal dress code applies, and clean casual clothes suit the whole route, which runs through village paths, small boats, and temples. Formal wear has no use aboard.
| Occasion | What to wear |
|---|---|
| On board | Quick-dry top, shorts or trousers, supplied slippers |
| Village and market visits | Covered shoulders, trousers or knee-length shorts, closed shoes |
| Evening meal | Clean shirt or light dress and one thin layer |
What clothes should you pack for an 8-night cruise?
Pack 12 garments, 5 pairs of underwear, and 5 pairs of socks for 8 nights—7 aboard and 1 resort night on the outbound sailing. Tops change daily and bottoms every 2–3 days, so one outfit lasts about 2–2.5 days. A capsule wardrobe, a small set of garments that combine into many outfits, holds the count at 12.
| # | Item | Quantity | Use |
|---|---|---|---|
| 1 | Underwear and socks, quick-dry | 5 pairs each | Daily |
| 2 | Short-sleeve tops, quick-dry | 4 | Daily wear |
| 3 | Long-sleeve shirts, light colour | 2 | Sun cover and temples |
| 4 | Trousers, long skirt, or knee-length shorts | 3 | One per 2–3 days |
| 5 | Evening outfit | 1 | Resort night, Phnom Penh evening |
| 6 | Scarf or sarong | 1 | Temples |
| 7 | Packable, hooded rain jacket | 1 | Showers and wind |
Keep the same counts on 11-night and 15-night sailings and use the onshore laundry service; add one pair of trousers for 15 nights.
Which fabrics suit 75–91°F (24–33°C) and high humidity?
Choose quick-dry synthetics or blends, thin cotton, or a linen blend, and leave heavy denim at home because it dries slowly. Humidity slows drying in the water season, and items still dry on board between laundry pickups.
What does the weather from August to December mean for your bag?
Heat changes little from August to December, and rain changes a lot. September brings 10.7 in (273 mm) in Ho Chi Minh City and 10.0 in (253 mm) in Phnom Penh, so a rain jacket is a core item. Daily highs stay at 89–91°F (32–33°C) through the season.
| Month | High–low, Ho Chi Minh City | Rain, Ho Chi Minh City / Phnom Penh | Add to your bag |
|---|---|---|---|
| August | 77–91°F (25–33°C) | 8.6 in (219 mm) / 6.0 in (153 mm) | Rain jacket, waterproof pouch |
| September | 77–91°F (25–33°C) | 10.7 in (273 mm) / 10.0 in (253 mm) | Spare socks |
| October | 77–90°F (25–32°C) | 9.4 in (240 mm) / 9.5 in (242 mm) | Same |
| November | 77–90°F (25–32°C) | 5.0 in (128 mm) / 3.7 in (94 mm) | Rain jacket stays |
| December | 75–89°F (24–32°C) | 1.6 in (41 mm) / 1.1 in (29 mm) | Thin layer for 71–75°F (21–24°C) nights |
Normals are 30-year averages, so one year can differ. Sources: the Viet Nam Meteorological and Hydrological Administration (Ho Chi Minh City, 1991–2020) and Cambodia’s Ministry of Water Resources and Meteorology (Phnom Penh, 1982–2024).
How do you layer for rain, wind, sun, and air-conditioned cabins?
Layer a loose long-sleeve shirt for sun, a packable rain jacket for showers and wind, and one thin layer for evenings, the lake crossing, and air-conditioned cabins. A jacket frees your hands, which an umbrella does not. On lake days the captain checks wind at 04:30 and moves the crossing when wind passes 15 knots (17.3 mph, 27.8 km/h).
What do you wear to temples and the Royal Palace?
Cover your shoulders and knees at temples, pagodas, and the Royal Palace in Phnom Penh, and take off your shoes at temple doors. Covered means a sleeve past the shoulder and a hem at or below the knee; each site publishes its own rules.
| Site | Cover | Shoes |
|---|---|---|
| Royal Palace and Silver Pagoda, Phnom Penh | Shoulders and knees | Follow the palace’s published rules |
| Pagodas and temples on both banks | Shoulders and knees | Off at the door; slip-ons help |
| Angkor temples (Siem Reap extension) | Shoulders and knees | Follow the Apsara Authority’s rules |
Carry a large scarf or sarong in your day bag.
Which shoes suit shore visits, small-boat landings, and life aboard?
Pack two pairs: closed trainers with grip for village paths, kiln sites, and markets, and strapped sandals for small-boat landings and temple doors. Non-slip EVA slippers wait in each cabin and guests switch to them aboard, so easy-off shoes save time at boarding.
| Pair | Use | Specification |
|---|---|---|
| Trainers | Villages, kilns, markets | Closed toe, grip sole |
| Strapped sandals | Landings, floating village, temples | Secure strap, dries fast |
| EVA slippers | Aboard | Supplied |
Alpine boots have no use on these paths.
Which gear and documents belong in your day bag?
Carry a 15–20 L (4–5 US gal) day bag holding a passport copy, small notes, a waterproof pouch, sun protection, water, a charged power bank, and offline entertainment on every shore visit.
| # | Item | Reason |
|---|---|---|
| 1 | Passport copy, paper or phone photo | The group leader holds passports during border formalities |
| 2 | Small notes | US dollars circulate widely in Cambodia; dong suits Vietnam |
| 3 | Waterproof pouch | Protects phone and papers from rain and splash |
| 4 | Sun cream, hat, repellent | Repellent type as the CDC lists it |
| 5 | Refillable bottle | Cuts plastic |
| 6 | Power bank and USB cable | 10,000 mAh is about 37 Wh; check your airline’s cap |
| 7 | Books and downloads | The vessel promises no internet |
Calypso Mekong has yet to state socket type or voltage.
What should your medical kit hold on top of the vessel’s kit?
Add what the vessel’s list omits, plus your own prescriptions in original packaging. The vessel carries a marine medical kit and medicine cabinet with bandages, splints, motion-sickness and anti-allergy medication, antiseptics, and oral rehydration salts. The nearest hospital sits more than 1 hour from the lake-night anchorage.
| Need | Vessel kit | Your kit |
|---|---|---|
| Wounds | Bandages, antiseptics, splints | Plasters for blisters |
| Stomach upset | Oral rehydration salts | Anti-diarrhoeal |
| Pain and fever | Not listed | Pain and fever relief |
| Allergy, motion sickness | Supplied | Your own brand |
| Bites and sun | Not listed | Repellent, bite relief, sun cream |
Bring your prescriber’s letter. Vaccines and antimalarials belong to a travel doctor; NHS Fit for Travel and the CDC’s Travelers’ Health pages list current advice. This page gives no medical advice and no doses.
What does the vessel provide, and what must you bring?

Questions about packing for a river cruise
Three questions come up after you choose the bag.
Can you wash clothes on a river cruise?
Yes, on Calypso Mekong: an onshore laundry service collects and returns items by a logistics vehicle that follows the vessel. Pack quick-dry clothes anyway, as the garment table above shows.
What does quick-dry fabric mean?
Quick-dry fabric absorbs little water, so a washed garment dries faster than cotton. Polyester, nylon, and synthetic-merino blends are three examples.
What should you leave at home?
Leave formal wear, heels, hard-shell suitcases, heavy denim, a full-size umbrella, and house slippers at home. Formal wear and heels have no use, hard-shell cases are refused aboard, heavy denim dries slowly, and the cabins supply slippers. The vessel promises no internet, so skip items that need Wi-Fi.
If your bag holds more than the tables ask for, return to the garment list and cut.
