OK, start with the fact that the outer shell is made from recycled PET bottles, and you've got the basis for something conceptually cool.  But how does it FEEL?  Thankfully... wonderful.  This is an exceptionally comfortable jacket with a soft, flexible feel and surprising warmth considering how light it is.  It runs a bit small/snug so if you're hoping to layer underneath with a sweatshirt, definitely order a size up.  While on its own it's not quite warm enough to weather brutal Minnesota winters, but it will definitely hold its own on milder winter days and all spring and autumn.

Plus, it's super cute.
