Use this Cap for training, inline skating, cycling, etc ..., there is in my opinion no better for Sport Cap. Fits well and is comfortable (assuming right size), plus the great price, what more could you want! The lanyard is quite nice, but I've been to the 6 pieces or so, but they're ready to be away-always good :)
The only thing you should not be, in the washing machine! After the cap is no longer usable, so rather hand wash, then there should be no problems. (Possibly also naming the gentle cycle ..., but I have not tried)
