Where can I can I get these?

[Jack Lewis]

I think the LASC and especially the AQUX are the nearest commercially available items, though it doesn't explain the mystery - because I don't think the guys in these photos are the type of guys who'd hunt down such swimwear. And they're more likely to be deterred by peer-pressure into wearing something more conventional. You're right there's a conspicuous lack of logos, but I can't see any photoshopping - again, why would they do that unless the photoshopping and uploading had been done by people other than the model? Attached is my attempt at achieving the look using some Mategears (sorry; wasn't going to shave just for this exercise) - but as I say I don't think this is what has been done in the cases we see elsewhere online.
