4.0 are the Best Pants Period

When it comes to 1620 pants. They're the best. I have almost every type of 1620 work pants, and the Stretch Double knee 4.0 are the Best of them all. Working with wet concrete could be a challenge for any type of clothing. Not for 1620, the concrete comes right off. They still look New. As soon 1620 stocks up on the Stretch Double Knee 4.0. I'm buying two of every color. 1620 can you bring back the Khaki, and add colors like Dermitasse and Hunter Green. It would be awesome if 1620 introduced the Sand color into the Lineup.


They're amazing


I got a pair for my husband, and the first pair was too big even though I measured the pants he wore before, but I guess these pants sit higher than the other pants.

Anyways I returned them and ordered another pants, this time the right size! My husband loves these pants and he says I ruined him forever because he can’t go back to the old pants anymore!

When I got the pants it was because he was complaining about how uncomfortable his work pants were, so I investigated and I’m so happy I found this brand!
I wish they made female clothing too!
