User questions & answers

Question: Do these shrink in the wash
Answer: I bought this for my husband who wears a 38. I have no idea how it fits. I do recommend a large for a 36 waist (he used to be that size, and he was a large).
Question: i'm 5'6" and 135lbs. What would be the best size for me
Answer: They have two front pockets but no back pockets
Question: I am petite (5'0"). however, i am 34 d and i think my hips between 35"-40". my question, does the sizing run small or bigger
Answer: I bought the small for 29 inch waist and said it fit a person 6'2", However the inseam was only 31" TOO SHORT as I have a 35" inseam ( 6'1" tall) and I looked thoroughly through the info and the only mention of inseam was "fits a 6'2" male. The quality of the pants good but too short.
Question: Are these smooth and soft or have irritating seems in them? I have very sensitive skin and cut every tag off of everything
Answer: Ordered XL for my 85 year old father, he's a 40-42" waist - and they were too tight in the waist, plus all us son's have tree trunks for thighs/legs - thanks Dad! Going up to 2XL - which he wasn't happy to realize, but that's what happens when you sit in the recliner and watch tv all day - what's an old dude supposed to do? :)
