I own two pairs of 1620 foundation pants, and I think they are some of the best work pants I have ever owned - durable, comfortable, and stylish. I always wanted to try the shop pants and finally decided to buy a pair during Black Friday. The shop pants are by far the most comfortable pair of pants I have ever worn. Like the foundation pants, they are very durable and very comfortable. The leg pocket is great feature for people who dislike putting their phone in their front pockets. Highly recommend these pants.
