I bought one about 4 years ago. The LTM6c. That's the one with the cape to protect your neck. I love this thing and wear it all the time. It's finally falling apart though. I went to order another one and noticed it had been replaced by the LTM6is. The price is about 20 bucks more than I paid back in 2010, but I think they are worth it. I receive the thing and realize what I have ordered has a "permanent" application of permethrin. Now I can see this being necessary for some, but I still can't bring myself to wear it in the Florida humidity. I mean, you adjust the thing frequently, so your hands are touching it all the time. You have sweat running down your face constantly. And if not that, rain water dripping from it. I just don't like the idea of it. And even though they say it's permanent, it says to wash separately because some will wash out. Guess I'm just venting. Maybe I'm unnecessarily concerned with it. But I can't figure out why they dropped the LTM6c. Contacting them about it wasn't much help.
