I have FD/Virtika outerwear from every season except for the 2nd. It's very obvious that the quality has gone up every year. My V3 stuff is still incredibly warm and in very good shape. The jacket has one cut from hip-checking a tree, otherwise not a single thing has gone wrong with it (+/- 150 days on it). My V3 pants are a bit more beat up. The crotch ripped out, on the inside, after about 100 days of use. The outsides have fared much better, with only one ski cut on the inside of the leg that needed stitching (I keep a razor sharp edge on my non-park skis).
This season I picked up a V4 jacket with 3L pants. They both have about 25 days so far. Jacket is just as good as my V3 jacket. No problems, and the same fit. The 3L pants, however, are even another step up. I absolutely love them. The fit is slightly slimmer, the fabric feels a little tougher and thicker, and I've gotten multiple compliments on the color (seafoam). The insulation is a little less, causing a little less bulk than previous models. But they're still warm enough that I only wear my Under Armour or Stoic baselayer pants. Durability wise, I don't know, I just don't have enough days on them, but, with my sharp ski edges, still no cuts or rips.
The only thing I think that dropped in quality is the Classic Badge hoodie. Not that there's anything wrong with it, but my Octo hoodie from last year is REALLY nice, with the high quality smooth zipper and heavy fabric.
I'm really considering picking up another pair of the 3L pants for patrolling the rest of the season. And for the OP, I'm 6'1", 180, and I wear size L pants and jacket this years stuff, and L pants and XL jacket for previous season's stuff.
