Kuryakyn 5281 Momentum Hitchhiker Motorcycle Travel Luggage - Waterproof Trunk Rack Bag for Touring & Commuting, Black | Durable Storage for Long Rides & Daily Use

Bought this bag for a 2500 mile tour from Seattle to Jackson, WY through Yellowstone and back home with the wife. Bag performed flawlessly. Not a bag to hold helmets, but I believe it is the perfect size for a tour pack topper. Easily held two pair of rain gear, sweatshirts, snacks purse, glasses, face masks, gloves.... the list goes on, and all the lotions and potions the wife brings along for sunscreen and such. Basically all the stuff she always wants to have access to every time she gets off the bike. Made a great addition to the saddle bags and the tour pack, and when packed right, kept us from needing to get into any of the other bags until we stopped for the night.This is a well made, rugged bag, that is sleek with a low profile. Not just a big fabric box. It holds it’s shape when empty, but I think too many miles empty might cause it to collapse. The left and right edges are rounded, and seemed to fit a rolled up rain suit perfectly. The bungee system on the bottom is great and holds fast, but I’m not as big of a fan of the Velcro tabs on the four corners. They work just fine, but they are just tedious(IMHO) to attach, but the benefits of this bag far outweigh this small inconvenience.In short, after all that blathering, this is a great bag. If you want to put helmets in a bag on top of your tour pack, keep looking.... but if you want a solid tour pack topper that looks good, roomy and sleek, buy this one.
