I got these to use for snowboarding & so far they have worked great.  The fabric, stitching,& hardware are all heavy duty (as you would expect from carhart). I had to order a large to get a tall size (why aren't tall's available in medium?) with my 32" waist I have to wear suspenders to keep them up & I have room to wear many layers under them.  There is no fly zipper so you have to unzip the side (I just pull them down as the waist of mine is oversized) for nature calls.
