Translated from Italiana
I was looking for the same model but with elastic and clip on the back but it seemed that it was no longer on the market, so I ordered these which in the photo were identical but without elastic and clips. To my (positive) surprise they came with elastic and back clip, great! However, the photo of the site must be updated as I thought they arrived like this due to a case / error; reading other reviews I understand instead that this model is probably made just like that. Satisfied, use in jet ski / marine.
