If I was a multimillionaire and had heaps of spare time it may be possible. More than likely I'd probably just snowboard all over the World......, living the endless Winter. The small handful of reviews I do is from gear I paid for by myself. I'm lucky, as I'm old enough (almost retired) and have a decent income stream/job that I can afford to do this. The likes of TJ, SPC, Avran, TGR, Buckhouse, Tommie Bennett, Knapton, Malcolm Moore etc all have the technical skill, ability and presence to create decent content however I'm pretty sure none of these guys are rolling around in the cash from just doing their YT channels. Sponsorship would be a massive boost for their income stream. In this day an age, life's definitely not cheap.Wait, are you talking about yourself, Craig?
Seriously tho, this is a huge grey area in marketing and I wish the channels emplyed a more solid transparency policy. That solves most issues, real or perceived.
