the ambi-pant

The Ambi-pant is a strange hybrid trouser that prevails in the menswear department of REI in which two-thirds of each pantleg can be removed through a zipper affordance, effectively converting the pants to shorts.

The Ambi-pant bears a resemblance to the mythical unicorn (known to reveal itself only to young virgins in tranquil forest settings) in that it can be found cavorting only under certain conditions (like -- somehow, miraculously -- during a rushed lunch hour shopping excursion), but cannot be located through either a Google or REI on-site search query.

So dominant is the Ambi-pant species within the REI menswear department that the probability of finding men's pants that are NOT all ambi-like is about as likely as, well, a well-travelled old dame like me stumbling across a unicorn.
