Deliberated quite awhile on these pants and camo pattern. Built well, fits great, nice fabric and really cool pattern. Glad I purchased.

Fit:
The pants are true to size in 36x31 and fit well for my American 36x32 size. Inseam measured exactly 31 and with boots I don't think I'd want to go to a 33" length.
They will fit over a thin/med winter base layer but I don't think they are intended to be an over pant on top of other full pants and thus are not oversized. Legs have plenty of room but not too baggy.

Features:
Knee is 4 layers total, 2 ripstop, 1 nylon or poly lining and a thin removeable closed cell pad.
Waist is an interesting system and should work well but I'd still like to see a few belt loops for an emergency. Zipper accessible without undoing the waist and zips from the bottom.
Fabric is a nice ripstop typical of what you'd see in a BDU pant. Def not cheap or thin.
Bottom 40% of legs zip open a few inches wide with a sealed gusset, very nice if your boots run thick.

Camo:
Wasn't sure about the pattern, looked at all photos I could find online, plenty of comments about its colors.
Pattern looks real good in person and I think it will perform well in a snow and vegetation mix. The pink is not pink, its in the tan/beige/flesh family. The 4th color is a very faint yellow that you see in the pics. Its about 30-40% of the colors and we'll see how it performs.
I think its a really neat pattern and a unique opportunity to own it.
