STRETCH
Hands down the best pants I’ve ever owned. I didn’t think it could get better than the OMP in slim fit, but it just did. Definitely will get in all colors before it’s over. I’m 5’ 7 160lbs. The 30in inseam works out for me in the slim fit. Most 30in inseams are too long but something about the fit makes these work. Very happy customer.
Joe | January 24, 2019Wow MK just got better!
These are hands down the most comfortable pair of pants I have. Just ordered a pair after owning many pair of Teton Twills and OMP but these are light and extremely comfortable with the stretch! I will be buying these in every color.
Sycamore47 | January 9, 2019My new favorite pants
I'm 6' even and 170lbs. The 34W32L fit perfectly. Leg room is baby bear perfect- not too tight not too loose. The guys in the office were actually inspired to search these out when I wore them in. Easily dressed up and doesn't look too goofy tactical, but really practical. They are my new go to pants.
Otto Von Metz | December 29, 2018Good service
Others have commented on the quality of the product, with which I agree, so I will not go into that here. I will comment, however, on the good service I received. After trying them on, I exchanged a "relaxed" pair of pants for a "slim" fit. The exchange was promptly handled without question, and all necessary adjustments to my credit card were made. Thanks. By the way, I am 6'1" and 176 lbs. and "relaxed" was way too big for me; get the "slim"if this describes you.
Peter | December 12, 2018Leap of faith!
I took a leap of faith and got the slim fit AMP's! All I can say is wow! I'm a big guy 6-6 260 lb and I was worried about the slim fit meeting my needs. I always go with the relax fit but will be buying more slim fit from now on. For those who already own any MK pant you know they fit and look great not to mention how functional and durable they are. For those of you who don't own a pair I would highly suggest you do so quickly.
