The bandages have a very massive (but this really flexible) and are suitable thanks to a length of 2m for each leg really. I (1,87cm tall) can wrap very generous with the bandaged my knees. The knee problems are passé since the use.
The Velcro keeps really well, even with langanhaltener load (eg leg press and 8x8 training) the bandages between sets do not need to "tightened" to be.
If you look at the prices of other bandages, they can here from Best Body Nutrition already as a price / performance deals are seen.
