Help me ID this Longchamp

I am totally new to the Longchamp line, but I feel an obsession coming on, lol.

Last week, I was on the train, on my way to work and I noticed a woman with a lovely tote bag slung over her shoulder...it did not look like leather, but also did not look like fabric really...it was some kind of smooth, somewhat glowy material - in the most gorgeous shade of orange/yellow/gold..it glowed really, but did not appear garish or too loud.

As the train came to my stop - I had two seconds to ask her who made the brand....she told me it was a Longchamp - not enough time for me to ask her for more details....

Can anyone guess which bag she might have been carrying?

Thank you!
