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

Can I suggest u join babywearing singapore Facebook? There are many reviews there base on brand if I go to the photo albums - u will see it - many many reviews. If u are just ok w any - then the Tula or the ergo both have mesh versions. For wrap conversion carriers, u have to see what is wrap made of, cotton only is comfy but not much strength - which some linen or hemp or bamboo content will have. Canvas will usually be hotter. But frankly, I am seldom in a non - air con place and it's not as if I am going to be out that long or walking in the park in the afternoon. But if u are scared of heat kind, mesh, linen, hemp, bamboo contents are going to help
