I agree with the previous reviewers take on these. They are just about perfect. I’m not a huge fan of the NYCO fabric pants. They are too stiff for my liking so I usually wear shop pants and then I tried these. Wow. A little thicker than the shop pants but similar in feel but better if you can imagine. Fit me better than any other pants I’ve worn. 6’ 195-205 and the normal size of 34” is better than anything else including the shop pant. I’ve already ordered two of these and got on here to order a third. To have these when it’s a little cooler and the shop pant in the extreme heat is a perfect mixture. Love them. Can’t say enough good about them.

These pants will change your life not over the top stretchy but overall just amazing. This is my 4 pair of 1620s but my first stretch and man I am in love. I know they are expensive but trust me when I say they are worth it. From fit to finish these things are bad **** and ready for work.

Huge 1620 fan

Been an enormous fan of 1620 since they launched, more or less an unofficial brand ambassador/evangelist up here in AK, but had to return this new redesign because the internal slit pockets are too close horizontally to the opening of the main pockets, and as a result I ended up awkwardly jamming my sausage fingers in the smaller pockets whenever I was trying to get something out of the larger. In a perfect world they would be a little higher up on the pant to avoid the problem, but will remain a steady/addicted customer regardless.
