Yes, the other site is the one with only one inseam size. I saw what is on the Clothing Arts site and that is why I made my post. I addition to the multiple size options Clothing Arts also offers several color selection options.
These pants enable a multitude of options when paired with the multiple pocket jacket from Scottevest and the hidden pocket Cool Weave shirt from LLBean.
The Dockers pants with one zip side pocket are also available from JC Penny's.
They have been my travelers for a while and the side pocket is a good place for a wallet when sitting for extended periods.
I am "old school" and prefer the pants from Magellen's with two zippered pockets for business meetings and dressier dinners.
