These are my kids* “go to” for goggles due to their reliable fit and great range of colours. There’s a choice of nose clips - not the easiest to change but only need to do it once and then you’re set.
Arena ought to make spare straps though - better for the environment and would make for less stressful Galas. Snapped straps at the blocks only have to happen once tor the fear to set in!
