This is a unit of a shirt. Super resilient Japanese cotton will keep you impressively comfortable and protected from the elements in this beefy button down technical shirt from Vollebak. Their Lumberjack line is sleek and professional enough for an office environment but will take care of you out in the world like no normal dress shirt. This one in particular has less gadgets and tricks than some of Vollebak's other offerings, but it offers you exactly what you need for a hike, site-visit, exploration, or adventure - sturdy reinforcement, huge chest pockets (both flap pockets and zipped pockets) large enough to fit all of your gear. This shirt is a size medium and fits relatively loosely. I'm 5'-9", 160lb and it's a bit big for my liking. As you can see in the photos, this piece is in excellent shape and will keep you looking and feeling right for a few decades hence. Vollebak's shirts last like nothing I've ever seen!
