This style of Julbo sunglasses fits my son really well. He has had the Julbo Looping 1 and 2 which worked well but he has outgrown. This has the same head-hugging style and works well. We tried another pair of a different style earlier this year and they didn't fit nearly as well. Highly recommend this style.
These are adorable and seem to be very well constructed - and they really stay put. The jury is still out as we have only just received them - we'll see how 'destructo' (our son)does - but so far they have far outlasted any other sunglasses he has owned. We live in Florida so sunglasses are very important for children - added bonus . . . he loves them and thinks he's the coolest 3 year-old around!
