Replying to DECISION TIME

so i went around today looking for helmets and ive pretty much decided on the RED trace helmet. Every shop i went to either only had mediums or had medium and xl. I tried on the medium without a beanie on and it fit perfect...like a helmet should fit on a head. The problem is that i wear beanies under helmets so i don't know whether i shoud go with the large or would it be a good idea to take out the little pads inside the helmet? Right now im leaning towards going for a large, but since i had no way to try it on, im a bit stuck... any help would be nice.
