This particular Aveeno product is a Skin Relief body wash and is the best, unfortunately it is not marketed in the UK and I came across it in the USA on holiday. I have had several pairs of Tevas over the years and have hiked and climbed with them. Though the velcro doesnt offer too much lee way in flexibility, they do offer some. You usually have to pay a little more for 100% cotton which is the most comfortable fabric, and which breathes the best to help regulate hot/cold. Soft and fluffy! I did need help because my arm strength sucks but if I was swoll I could do this on my own, no prablem. One of the last paragraphs, after all the installation steps tells you that one is longer than the other and it goes on the front. The sound isolation and extra cables make the purchase a decent value. I opened and closed the lids several times with no issues. Love the beats.
