I got my ub suit in the mail yesterday just in time to try out while stocking mating nucs in hot/humid weather. I got the xl size and it fit perfectly. It seems very well made but was heavier than I expected. When soaked with sweat my cotton suit would be much heavier though and the material in the ub suit doesn't absorb water so it's a trade off. I wore it yesterday with only boxers on and it was uncomfortable. The material is stiff and rubs at every protrusion. I'll wear shorts and t-shirt now. I don't like the hood style but I won't need that most times. It was much cooler than the old suit and any little breeze goes through the suit and really helps a whole lot. So far I like the suit and am happy.
