Good tension in the elastic. I use this for airplane travel and long car rides. After some researched I decided to try it when running. To my surprise, It made running much more comfortable, especially afterwards. i thought my running days were gone, but I was able to train up to 1/2 marathon with this. I also have started to wear on the bike trainer some times. I am 5'8 only complaint is is it a bit long or wide however you want to say it, when bending or leaning over, it digs in a bit, but that is a small complaint. Quality is good after a lot of use. I got through a 1/2 Ironman wearing this!
