Welcome to the M4: a svelte, rugged piece of your day that will keep the blisters and thorns away no matter what you're up to. A day across the Alps, a back-yard wood-cutting session along the Maine coast. We're certain the M4 will look equally at home cutting winter wood or walking down East Bayside for local oysters. Your call.
