As a slightly different option than what /u/Less_Fat_John shared, I've had this 2-pack for 3 years now and have worn one or the other daily and they are still in great shape. You can get them up to 62" long and they stretch a few inches more.

I've had the other ones that were shared and they would tend to roll up on me after a few hours. These others are a lot wider and I don't have any issues with them rolling up.
