I have lately started using swim caps to put my tempo trainer under. I bought some TYR silicone cap and while I have been wearing them for a few weeks, they are uncomfortably tight around my head every time I use them. That is regardless of whether I have the trainer placed inside or not.

I did not think I have an overly large head and also do not wear long hear.

The caps all come in "one size fits all" at least from what I have seen so far.

Does somebody have experience with caps that come in a little larger? A different brand or material maybe?

Thx in advance for any good advise.
