• Ok, I just tested the sports cap... and burnt my fucking tongue!
    Shoulda seen that one coming! :)
    The cap itself can take the boiling water fine, but there's no way of knowing if it's still red hot until it's too late. :)
    I would say regular cap for hot drinks, sports cap for cold drinks.
    If I ever get a reply to my emails I'll find out if I can mix and match the caps and make separate orders for caps on their own incase anyone would like one of each.
