The best place to buy it is right from ASAT! They have a money back guarantee that of you don't like it after 1 year they will buy it back.
The leafy suit is an over suit. You can wear it over your insulated coveralls in the winter or wear it over shorts and a t-short when it's hot out.
As far as sizes, I'm 5ft 8in and 190 lbs and wear a size 32 waist pant. The suit is a little baggy on me but I wanted to be able to wear winter clothes underneath. Warm climate hunters may want to get a suit that fits closer to their size cause you won't have as much clothes underneath.
These suits are tough as nails!!! The leafy material is stitched to a mesh material. I thought the mesh would tear as soon as something snagged it, but I've beat the tar out of the same suit for 4 years now and it's going to last MANY more. Been through many briar bushes and the like without incident.
I've tried Predator, Realtree, Mossy Oak, Sticks and Limbs, Trebark. ASAT whips em all especially when it comes to having spots with minimal cover.
Last year, I took this buck out of this tree. Not exactly a ton of cover,LOL!
