Which baby carriers have the best material for SG's hot and humid weather?

There are a variety of wraps that are popular among mummies in Singapore like the Emeibaby, Koby wrap, Meitai or just purchasing cooling materials (length according to your body size) and using them as wraps or slings. I would recommend you choose wraps that are made from cotton rather than wool or silk which are warmer and harder to care for. If you are looking for a structured carrier, the ergobaby sport is a good choice as well. The front is slit-vented which is cooling for baby.
