Boreas - Buttermilk 55 - Men's

Buttermilks are light and uncomplicated. They’re designed for those who want to move really, really fast and those who think it’s just plain crazy to carry heavy things around in the woods.

The Buttermilk 55 features a z-foam back panel and removable frame sheet, shaped to match the curve of your back. Poke the z-foam and you’ll see it springs back. That compression/ reaction motion happens as you hike, pumping air through to keep your back cool. High quality foam provides comfort by distributing pressure evenly and maintaining volume under load.
