I purchased this vest for an upcoming ultra to replace a more expensive one. I am extremely pleased with the design and quality. I don't think you'll find a better vest in this or higher price ranges. Sadly, my race was cancelled but I was still able to put this vest to it's first true test when I took the train to Ledbury and ran 50 miles home. The vest did not let me down and I'm confident it will be a faithful companion of mine for years to come. In particular, I'm very impressed with the storage in the front cutting down on the times you need to take off the vest. I do suggest purchasing a size smaller than what is currently being suggested. My chest size is in the middle of the Medium sizing, however; I've had to tighten it to the maximum and it just barely fits tight enough and ideally would be a bit tighter. Other than that, I'm more than pleased with my purchase.
