• I've done a swim cap on a Mask mojito, mainly to try to reduce quite how we t I'd get as I Knew I'd be able to see fuck all in my tt helmet due to a non removable visor and torrential rain no idea if it's faster though, I used a latex on as they are a bit more solid, there's also the possibility that the helmet won't do such a great job of protecting your head as rather than slipping over the ground it'll be more grippy..
