Parenting is a full-time job and there simply is not enough time in the day to read through Tolstoy's War and Peace so let us cut to the chase.
Pick the Airflow if:
You live in a warm humid country with only 1 season (read: summer) or one with mild winters.
Pick the All-Seasons if:
You need flexibility and the carrier is a fashion statement (Why Not?). As the name implies the All-Seasons is meant to be used for all 4 seasons - letting you unzip to reveal its mesh center paneling when it's warm and letting you batten down the hatches when the next polar vortex hits.
Devil is in the Details:
Structurally these 2 are identical. So expect both the Shoulder Straps and the Waist Band to be the same. The difference is the center portion of the carrier. The Airflow is totally mesh (except for the zip down patch, but it does zip down to reveal more mesh). The mesh also explains why the colours and designs on the Airflow are more simplistic - you try painting a Monet on a canvas full of hole - things get "Messhy" (see what I did there?).
The All-Season has a fabric exterior on the center portion of the carrier, only the very center of the carrier zips down to reveal mesh. Explains why all the All-Seasons have the fancier designed - cool kids have all the fun (weather that is...)
Personally, for Hong Kong, the Airflow is my go-to option. Winters here are generally mildly cold and if it gets chilly, both you and baby will be wrapped up anyway. It is infinitely easier to layer on than to peel the sides off a carrier right?
For those intrepid adventurers who intend to survey the arctic or go photograph the Northern Lights... All Seasons, all the way. You get the idea, if you intend to spend any decent amount of time in Colder climates, then the All-Seasons is for you. We find the All-Seasons may be a bit to warm for all you hot parents (Temperature hot... temperature).
