I just received my first pair of Stretch 4.0 pants. The material on these pants are amazing. The pocket design and layout is fantastic. My only complaint is that the stretch material pants are not yet available in a slim fit. I have 4 pair of the Slim Fit Utility Pant 2.0 that have become my go to pants that I wear every day. I am 6'3", 205 and the slim fit pants are a perfect fit and look great, but in the summer heat, the NYCO material pants do get hot. 1620, if you can make the Stretch 4.0 pants in Slim Fit, this would be the perfect lightweight, durable work pant (IMO). I came across 1620 Workwear earlier this year, and I can say that they make the best workwear that I have put my hands on so far.
