Alger because we ride the Alger Grade, one of our favorite local and remote gravel roads, and Draw because of the drawcord opening. It's the perfect seat pack for your shorter gravel (or road) rides, and it eats fat bike tubes, tools, and extra layers for lunch. With the drawcord opening and lid, it opens wide to quickly retrieve your gear when you need it. The two compression straps, coupled with an HDPE stiffener, cinch the load so it stays in place without sagging or swaying whether it's jammed full or completely empty. Capacity is approximately 3 liters.
