Giant Loop – Giant Loop Fuel Bags, including the Armadillo Bag in 1 gallon, 2 gallon, 3 gallon and 5 gallon capacities in both black and gray, this category exists for one reason: extra range where fuel stops are rare. A rigid can takes up the same room empty as it does full, and that is exactly the compromise Giant Loop engineered away. Each Armadillo fuel bag is a flexible bladder that carries a serious reserve on the way out and then collapses down to almost nothing for the ride back, freeing space in a saddlebag, pannier or duffle. Because the bag flexes, it settles into the contours of your existing load rather than forcing you to build a rack around it, and that lower, tighter packing keeps weight where suspension can manage it. Riders who run remote desert loops, long forest-road links, snow bike days or backcountry ATV and UTV routes size up or down depending on the leg ahead, often pairing a small bag for a cushion with a larger one for a full extra tank. Choosing the right capacity turns a nervous out-and-back into a genuine point-to-point adventure. Pack a bag out full, ride the remote section with confidence, then flatten it away.
