I'm looking to get a mask that works well with glasses but also works with a helmet or full head mas and so far found only two which are the hawkeye and the jt flex 8 both are similar priced so no really sure which is the best choice, never used the hawkeye so am no sure how it is compared to the flex8 and don't want to end up spending money and no liking it and being out of pocket, used the flex 8 before and it was ok but want to make sure I consider all the options to get the best I can
