I get obsessed with various online subcultures. Usually they surround some well designed, niche product. Things like duct tape, shoe goo, bespoke suits, gold coins, and headphones. Often I find my way into little communities of people I would never be able to engage otherwise.

I recently was shopping for a new bag and stumbled into the world of one-bag carry-ons. It is a world of frequent flyers, retirees and business travelers, engineers, and IT folks. People talking about their body sizes, made in the USA production, toiletries, laptops, and synthetic pants. Friendly folks with above average incomes and educations. They have something in common with the ultra-light campers but with a very different aesthetic.

If you want to follow me down the path here is the map. A lot happens in the comments and reviews.

On the other hand it might be best to stay away if you don't have some money and time to burn.
