I have a 'small' DriDucks set.
The jacket is 45" in girth, straight (i.e. not tapered eithered way.) Back length (from the seam where the hood attaches) is 29.5 inches. Sleeve length, again from the neckline, is 33 inches. Armholes are very generously sized. Weighs 5.5 oz by my scale.
Pants' inseam is 29", outseam is 41". Waist is 29" relaxed, 40" stretched (which is also the same girth as the hips.) Weighs 3.7 oz.
I'm a 5'2" woman and I swim in it, but while it's not exactly an "attractive" fit, I can wear it fine.
I have to say, though, that at first glance, the fabric doesn't inspire a lot of confidence. My first thought was that it reminded me of those paper/plastic "bibs" at the dentist's office...
