I've bought some stuff from my local cyclegear store
https://www.cyclegear.com/tank-bagsBILT products are cheapest made usually won't last more than 3-5 years before ripping seams but then again only cost 1/3rd the cost as well and do carry a no questions asked 1 year warranty. I got one bilt bag replaced under 1 year warranty a seam broke open took into store replaced free of charge with receipt of course.
