This is exactly what I've thinking lately when I've been watching some YT videos. I'm watching someone (a AU/NZ bloke) who's flip flopping TA and he did some PCT couple of years ago and he's fully kitted with American gear from Dirty Girls to BA Copper Spur. There's nothing wrong with that, but it just shows you the influence of American videos & marketing. There are also couple of UK YouTubers who are heavily influenced by this. I'm not impartial to this myself. When I got back into hiking a few years ago, I came across r/Ultralight, which of course is full of Americans with experience from mostly US trails with US kit. It wasn't until I move back to UK and found this forum and did some hiking here in the UK, I realised that some of the US kit doesn't really work here or some other terrains. So thank you TL.com for educating me.
