Scenario 1: You start your frosty morning bike commute wearing your fleece, wind shell, gloves and hat (Arrowhead Trail Rolltop cinched down to 18-inch height). But the day warms up, and on the way home you need to stow all that stuff plus more work from the office…Aargh! (Arrowhead Trail Rolltop expanded to 27-inch height…and you can still buckle the flap straps!). Scenario 2: (substitute day hike in the Adirondacks). Scenario 3: (substitute trek to campus)…You get the idea. The simple adaptability of the Arrowhead Rolltop makes carrying a small bundle, or a large load, a breeze. If you’re only carrying a little bit, roll the 18 oz. waxed canvas top all the way down and cinch the leather straps to the bag. Need more space? Unroll the top. The long, harness leather straps and extended top allow expanded capacity. Waxed canvas is water resistant, and when matched with a rolled top it is especially weather tight. There’s a loop for a blinking bike light, along with lash squares to tie stuff on… it’s a waxed canvas commuter pack that’s made in Duluth and really hauls! Available in two sizes (13 in and 15 in width) and two pocket layouts (the ECO's add 2-in-1 pockets on the outside, (think water bottle pockets) and internal sleeves (think laptop or hydration bladder).
