Installed Exfil-18's on my Harley 48 with OEM mounting brackets. They look really good IMO, are very functional and so much better than having to wear a backpack. The zippers, materials and the build seem very sturdy. I like the features: Extra pockets, molly straps, double zippers, portable. I keep a toolkit, a tire repair kit, some rags, the rain covers and a fuel bottle in them and there is still a ton of room for daily stuff or longer trips. They don't get in the way when I two up. I Like them!
