Moving to a hot climate
Short answer: Switch to thin, loose garments in light colours and keep more sets of underwear than you are used to. In humid heat you change often.
What changes
In a hot climate clothes are worn in fewer layers but changed more often. That means fewer jumpers and jackets and markedly more sets of underwear, t-shirts and socks. The number changes more than the type.
Fabric and cut
Loose cuts that let air circulate, thin qualities and fibres that absorb moisture matter most. Bamboo viscose and linen both work well. See bamboo t-shirts for men.
Underwear has to change more often
In humid heat, underwear and socks are changed twice a day. Expect double the number you had before. See bamboo underwear for men and bamboo socks for men.
Frequently asked questions
Should all winter clothing be sold
Keep one set for trips home. The rest just takes up space.
Are light colours better
In direct sun yes. Indoors, cut and fabric matter more.
What about air conditioning
Indoors it can be cool. A thin layer you can put on covers both.
