Help Finding a pair of walking/backpacking shorts....

Hello,

I am looking for a similar short to one I purchased about 5 years ago and I can't find anywhere online. Can you please help?
The ones that I have are Brooks brand and I think I bought them here. They are perfect for backpacking and long distance walking because they don't chafe.

The shorts have a long inseam - almost 8"
They have a spandex liner that runs the full length of the short and the spandex is sewn in to the short.
The outer short is nylon - similar to a boys swimsuit.

I am open to other brands - I just need a similar design.

Can you please help?
