Ive just bought myself a set of 2 piece leathers and the pants feel way too tight. They fit well around my waist but when sitting on the bike with them zipped together, they pull uncomfortably on the back of the jacket, also there is a lot of pressure from the suit pulling on my knees and i can barely bend my legs. I know leathers do stretch a bit but how much will they give? I was able to ride my bike around town ok but im not sure I would be able to stick my knee out very far if i find myself on some twisty roads. Should I swap the pants for a size up? Should I HTFU and bend them to my will?
