Groovy vintage 1970's khaki flat front pants with hugely wide flare legs, maker unknown.

Medium to heavyweight poplin, likely a polyester cotton blend.

Features beige stitching details.

Size:  Unknown, measures between 34 Waist (comfy) and 36 Waist (doable)

Waist:  35" 

Rise:  11"

Inseam:  30" (plus 3.5 " hem)

Across at hem:  11.5"

Appears the waist has been let out as you can see the original stitching on back side (see photo); a few light smudges here and there near the hemline which I have not tried to remove. 

Overall good to very good vintage condition with light typical wear.
