I wanted these as they are light, economical and have pockets for my wallet and phone. Laid flat, they are basically shaped like a giant rectangle in shape.
I ordered L/XL based on my 36" waist size on the size chart. BIG mistake! I could hold the front of those pants out a good 10" from my waist! Thanks to MR's great customer service, I easily swapped them for the S/M which still have some room to spare. I measured the folded waist at 21" across and the length from top of waist to bottom of leg at about 41".
