The best four season jacket we ever made! This jacket is the reason why we are RICHA. It’s a complete jacket for each season along the year. From heat waves to freezing temperatures, from heavy rain showers to high level of humidity, this jacket will protect you through each weather condition thanks to its AIR VENT SYSTEM (AVS) you can breathe while keeping your body dry because it expels the moisture/sweat quickly away. No matter how much rain falls on you, you will always stay dry! The construction of the Infinity consists of 2 detachable layers: the 8000mm removable layer membrane, and the removable thermo liner.
