The outer fabric is elastic and light, but not limp, but quite firmly. In bright colors of the outer material is probably translucent, which have indeed criticized other reviewers. The pants have no pockets, the inner lining is made of fine non-woven fabric, not of coarser mesh material, the rubber in the inner slip-leg openings and the waist band are strong.
The color "argon blue" is a nice strong steel blue (like the small nails holding), slightly glossy, slightly lighter than navy blue but much darker than Royal Blue.
The sizes seem calculated rather lush, I will tell you who is on the border of two sizes, can also choose the smaller: 1.84 m, currently still winter fat 90 kg ;-) and from many marching strong gluteus maximus is me Size L to limp.
