Should I bring jeans?

No. Denim is heavy, traps heat, and takes 24+ hours to dry. Wear lightweight chinos or linen trousers instead.

How do I keep my clothes from smelling in the heat?

Pack a small bag of cedar balls or dryer sheets to keep in your luggage. More importantly, bring a mesh laundry bag so your worn items don't sit directly against your clean ones.

Is it better to wear loose or tight clothing?

Loose clothing is better. It creates a 'chimney effect' that allows air to circulate between the fabric and your skin, which helps sweat evaporate faster.

Packing for Hot Climates Without Overheating

Stick to natural fibers like linen and merino wool and limit your luggage to a single carry-on. Prioritize moisture-wicking base layers and versatile pieces that can be layered to account for aggressive air conditioning.

Select only natural or technical fabrics. Avoid synthetic polyester. Opt for 100% linen, bamboo, or light-weight merino wool. These materials allow your skin to breathe and dry quickly if you wash them in a sink.
Apply the 'one-third' rule for volume. In hot climates, clothes are thinner. You should easily fit 7 days of clothing into a 30L bag. If your bag is full before you pack your shoes, you are bringing too much.
Choose light colors. Wear white, beige, or light grey. Dark colors absorb solar radiation and make you feel 5-10 degrees hotter in direct sunlight.
Account for 'AC-shock'. Carry one lightweight button-down shirt or a thin cashmere wrap. Buses, trains, and malls in hot countries are often kept at 65°F (18°C); you will need a layer to prevent catching a cold.
