What is Arcteryx atom?

Could you please clarify what Arcteryx ATOM refers to? Is it a specific product line by the outdoor clothing brand Arcteryx, or perhaps a term related to cryptocurrency and finance that I'm not familiar with? If it's the former, I'm assuming it's a range of high-performance, insulated clothing designed for cold weather activities. However, if you're referring to something related to our field, I'd be interested to learn more about the context in which this term is being used.
