Very disappointed with the fit for a meduim. The arm holes were too big and the drop of the vest too long. Why do maufactures insist on producing a mans sports vest to look like a mini dress. The drop on this vest should have been no more that 75mm passed the top of your shorts. Instead it was 50mm from the hem of my shorts. I'm a 5- 11 height and meduim build and weigh 12 stones.Got this in a 2XL. A size 16 boy couldn’t even fit into this. It’s hard and has very little stretch and the sizing Is off. Returned it !Good basic product to go at the gymPerfect fit when I brought it put on weight since good quality well madeProduct is fantastic. Fits well and exactly as described ✅✅✅✅
