These straps are very easy to attach, change color and customize the fit. They don't loosen up much when you wear them which is great. I was concerned as the packaging was relatively cheap the plastic thing used to tighten the band/slider would slip and come loose when worn - it doesn't! I wear them bodysurfing and swimming. No questions.
