Core Shot unisex backpack
I bought this pack in June for everyday commuting. I didn't know it was a winter pack. I was told it had really good back padding, which it does.
The only negative thing about this pack is mine has trouble standing up straight: twice, after emptying my pack and setting it upright on my kitchen chair, my pack slid down the chair, bottom first, and landed on its back on my kitchen floor.
So now, I try to remember tip my pack forward and push the chair in to the kitchen table to hold it upright.
