Rated 3 out of 5 by from Sooooo long These pants look nice and fit well except that they are long enough for Shaq. I will be taking them to the tailor along with the other Peter Millar pants I just purchased. Your QC needs to work on length.

Rated 2 out of 5 by from Baggy I found these pants baggy in the thigh and seat and overall ill fitting.

Rated 5 out of 5 by from I’ll buy some more of the other colors. Bought a pair about a month ago. So pleased. The flannel is heavy enough to be a fall or winter pant but it’s not too much. Could wear in early spring if you want to look good.

Rated 2 out of 5 by from Length a problem Echoing Tim above, I'm disappointed that I'm going to have to go pay a tailor to alter these pants for length. I can't be certain, but I don't think I had to do this the last time I bought this model, two years ago. I must have been able to order them to fit re: inseam. I wish I had paid more attention to this before buying, but I like the pants so much I overlooked it. It should not be the case that pants of this quality, at this price, can't be ordered to fit in the inseam. This is going to add cost and hassle to this purchase. I've previous been a happy PM customer, but I'm not going to order again until the inseam situation is fixed.

Rated 1 out of 5 by from The Length was way off The waist was fine but the pants were 5-6inches too long. How can you not request lengths?? $4 restocking fee?? Wasted time and money with this poor attempt and will now never use PM again.
