I ordered the One white/sky blue in F4. They accidentally sent me a white/black Gi but I went ahead and tried it on so see how it felt. The pants fit perfectly and they were so comfy. The top for me however was a little big. I’m one of those that require a smaller top and bigger bottoms. I emailed them to let them know I got the wrong item and within a day they responded to my email. Within my email I asked if they would be willing to do a F3 top and F4 bottom. Unfortunately they said they could not do that. I got the sticker to return my item for the correct color and I decided to exchange for a smaller size to see how it fits. We shall see how this one fits. So far the only changes I would like is the ability to interchange the tops and bottoms. For anyone who wants to try to get a better fit. I’m 5’ 7” and weigh about 164. I wear a size small tshirt but medium/ large gym shorts (10-12).
