Haggar Herren-Hose, bügelfrei, erweiterbar, einfarbig, vorne

Q: Are these a blend of both cotton and polyester ? I like poly, but not 100 %. Too much sheen usually.

Haggar's Classic Fit Premium No Iron Khaki is 61% Cotton, 37% Poly, and 2% Spandex. I have washed and lightly dried them a couple of times, and they are like new with no sheen.

Q: I love haggar's ! Do these have hidden expandable waist feature, or does it just mean the waist stretches a little when you put them on ?

The fabric stretches. No hidden expandable waist feature.

Q: I'm a waist size 35 - but they don't make that. So, I'm thinking 34 with the expandable waist feature should be okay ? 36 would be too big for me.

Size 34 with an expandable waist will work, but don't ignore a 36 size with an expandable waist. Some times after some laundry the size shrink a bit..
