The Jansport Diablo Fleece Jacket is a perfect companion for chilly fall days or on the slopes. Granted, on the slopes the Diablo works best as a layering piece, but that's what teamwork is all about. When it's being a naughty, anti-social jacket, the Diablo's hem drawcord helps seal the warm in and the cold out, while nylon overlaid shoulders give you an extra measure of protection against rain and snow, and keep your pack straps from chewing up your nice new fleece. After all, you'll like the Diablo so much you won't want to let it go.
