The Nepal Evos are easier to walk in as well, and have (or used to, at least) the Duratherm goretex, which is/was more insulative than the regular goretex and is probably why the Evos are thought of as warmer. Don't suppose there'd be much in it, though - if you really suffer, you're probably better with the Baturas, or maybe something like the Phantom Guides
