Nelson Rigg Trails End Motorcycle Fender Bags - Waterproof Durable Storage for Bikes, ATVs & Dirt Bikes - Perfect for Adventure Riding & Off-Road Trips

Ok, first and foremost: There is ZERO chance of this bag falling off if you use the included fork-tube straps that come with it. However, those straps are packed inside the bag's main compartment so anyone who doesn't look (or didn't read the single instruction page) might miss it. I feel bad that those reviews are bringing down what is really a 5-star product.The bag is thin in height/depth, yes. It's not like the big, boxy rear-fender tool bags. But that's because a) the front fender isn't generally designed to hold weight like the rear fender, and b) if it were any taller it would block your headlight beam. Again, not sure why people are deducting stars for an intentional design, here.As for the bag: The ballistic polyester material is super thick & sturdy, and PVC-lined so it's water resistant. Zippers are beefy and are the luggage-lock variety so you can throw a small lock or some wire through there for extra security against the zippers opening on the trail. The cam buckles are aluminum, and the straps are a nice, thick webbing. There are even elastic loops that keep the extra webbing from flapping in the wind -- a very well thought-out design. I've tried pulling hard but can't make the straps budge -- it's a very secure system. All junctures are box-x stitched for strength, which feels very stout. The metal clips that attach to the fender are rubber-coated, and the bag bottom is a soft, grippy/rubbery material. The bag is very well made.Here's a list of what I currently have in mine, and there's still a bit more room; it's not bulging at all. If you carry a full spare 21" tube, then you won't be able to fit all this stuff. But I prefer to use the bag more for an emergency tool/repair kit for my WR-450F so I'm not forced to put this stuff in my backpack (I don't use a rear-fender tool bag).I know this sounds like a lot, but it all fits perfectly:- 2 tire irons- Tube patch kit x5 (I keep a compact hand pump in my backpack)- Mini needlenose vise grips- 8" adjustable wrench (opens up to 27mm for rear axle nut)- Small coil of safety wire- 2ft Gorilla tape (folded)- Assorted zip-ties- 2-in-1 Phillips/flathead screwdriver- LED mini flashlight- Disposable gloves 1 pair- Shop rag- Small hotel bar soap (to use as tire lube and/or cleanup)- Hex key set- 1/4"-drive mini socket wrench with 8mm, 10mm, 12mm sockets- Combo wrenches in 8mm, 10mm, 12mm
