I have just bought a Jumbo Visma Team T-shirt from La Machine. Before that, I had searched online and had seen that many other places could not deliver the shirt yet. But La Machine had it and of course, I bought it there. Everything happened very quickly - perhaps too quickly. It was late at night when I ordered the shirt. I had rushed and ordered a shirt in the wrong size. And I only discovered the size guide on the website after I had ordered the shirt. But I sent an email to La Machine and asked if they would and could change the size even though I had bought and ordered a different size. The very next day I got an email from the crew, and a guy wrote that they had already changed the size to the right one. And they shipped very quickly. I have received the shirt - and it is awesome. It fits perfectly and the colors are absolutely fine. Even my teenage daughter was amazed and said that I looked like one of the riders or even the team manager of Jumbo Visma. You can safely rely on the size guide on the website. it works - even on a medium guy like me. So thanks to La Machine for really good service and to the guy that helped me in getting the right shirt without too much hassle.
