Club Obi Wan

I was looking at Wested's online order form earlier today, and in the "lining options" section it lists "cotton selisia" as an option. I feel pretty silly asking, but what exactly is selisia? I haven't heard of it before, and so far my searches haven't turned up any results.

Thanks

The key word that makes it Indy enough is 'sturdy'.
