Sling/Carrier for hot weather

Hi. Any recommendations on carriers for use in hot countries? Weather will be around 35C/95F for the 1st leg of our trip. Stroller won't be possible to use in the massive crowds and I'm considering a sling or carrier. My Ergobaby 360 is too thick to even be an option. My son is a hot person like DH. DS will be 2.5 years old but he is a tiny toddler. 81cm tall and 10.6kg (23-24 lb). Thanks.
