The Anza Stem Sack has quickly turned into my favorite bag on my bike. The Stem Sack mounts with one strap on your stem and one on your Handlebar. It’s perfect for carrying a extra water bottle, beer, extra layer, small camera or snacks. It has daisy chained webbing all around the outside of the bag and 3 small pockets to stash small snacks and items. The Stem sack works in perfect harmony with a Anza Handlebar bag. Simply loop one of the straps from the Handlebar bag through the webbing and your all set. The Stem Sack is made out of heavy-duty and water resistant Cordura and military grade webbing.
