I'm a big fan of these pants.
Material feels durable, yet stretches well which is useful for moving/building.
I love the functional side/back leg pockets that don't get in the way when squatting etc.
I wear a 12 in Levi's, and got a 12 in mavens. They fit pretty dang well. When sitting, they're a little stiff/tight in the belt/waistband region where my lil chubb likes to reside, but otherwise, they feel great.
30" inseam feels perfect (I'm 5'7" on a good day).
(Sidenote: i have a different pair of maven slims that I wore for 2 years, most days, and finally they got stretched out and didn't hold their shape, felt baggy. I've been told this new/updated version is a different fabric, so maybe that won't happen this time! -- also they changed the pockets a bit. The larger right side pocket is now about 2 inches deeper, which will protect my phone from sawdust more, but will be less of a quick-draw situation. No biggie).
