I picked up the 301OD from the SE sale after trying on a pair a few months ago and they had been lingering in my mind. Fit was fantastic. Sold my 777 21oz to make room. I like a higher rise with the stronger taper and the 301 really perfects the fit for me. 777 are just too low for me and constantly adjusting when I bend/squat. They come today so my life should change dramatically now.
I also really like that these are apparently very breathable like the 21oz as that was my favorite aspect of that denim.
