*by L***A on 15 October 2020*

So, on a recent multi day trip I needed a frame bag... and quick. After a lot's of reading, I settled on this Rockbros frame bag. The super cheap price, rigid nature of the bag and more importantly water proof feature really sold me - did I mention how cheap. Bag turned up in a few days too. The smaller left hand side was great for thin items (battery, nutrition etc) and the larger right hand side perfect for tools, tube, arm warmers & rain jacket. Soooo easy to access too. I also really liked the flexible nature of the multiple mounting straps. If this bag was 4 times the price, I'd still be happy. In a word - AWESOME!
