“Where are these pants adjustable, inside or are their straps outside. I want to make sure it is not just the belt loops that make them adjustable. My husband is a 34waist and 30 length. I think he needs is Medium according to the chart. I just don't want to mess this up. I bought him pants that were great on length but too small in the waist last time.
The pants have velcro tabs on the inside, one on each side. The fit on the L is good for him with the tabs pulling the pants in by about 2" on each side.(5'11", 170lb, and wears 34"x32"). He didn't try the M, so I don't know their length/width. We purchased these last year. He had tried the Columbia Winter Blur pants before: the M fit him exactly right if he never ever gains another pound, and the L were way too big.
