FS Luke's Ultralight windshirt, size L, argon 90
I'm throwing this out there too - i ordered a large to fit over my puffy but holy cow this thing is HUGE.
It is most definitely a big large, i might even say XL to be honest (if I were to compare it to Patagonia, or Arcteryx). I got the olive green, which is really more like an awesome brown.
I was going to return it, but before I do I thought I'd throw it out and see if anyone wants it without the 3 week wait.
I paid $90 including shipping - yours for $80 and no wait.
I'll post a picture later tonight. If there's no interest I'll just send it back. It's an awesome piece...
