The North Face says about the Paramount Convertible Mid Rise Pant Women's
The Paramount Convertible Mid Rise Trousers aren’t your standard hiking trousers. The lower legs zip off, becoming lightweight, comfortable shorts in warmer weathers. When the sun goes down, you can zip them back on again for additional comfort and warmth. Engineered with moisture-wicking, quick-drying FlashDry™ technology, these soft-shell trousers will keep you cool and dry, whatever the weather. And the adjustable, integrated waist belt delivers a secure fit, whether scrambling over tricky terrain or gunning down steep hills.
