Waterproof Saddle Bags TERRA TR30 – IPX6 Waterproof Adventure Side Bags, 60L Capacity, Double Locking System – Compatible with 3P & 4P System, Designed in Barcelona

I can't speak to durability, because I just installed them on my Versys X300 this evening... But the initial quality seems crazy good, especially at this price point! It's easy to take on and off. And it's LOCKABLE. I can finally stop for a few minutes at a restaurant or a store and not worry that someone is stealing all my stuff. It has ample storage for me, and still sits close enough to the bike to allow me to lane filter, if I chose to.For the few of us Versys X300 owners out there... I think this is a no brainer. Finally someone made a set of usable luggage that will fit our quirky little ADV bikes. Thank you Shad!
