This mat is definately worth the extra money. I practiced yoga five days a week for 4 months, blowing out one cheaper mat and causing significant signs of wear on the second one. Once this mat is broken in, I found it to not only be quite sticky, but also to provide excellent cushioning for me knees. It is also larger than most other mats, so there is less need to read just your position on the mat as frequently to avoid contact with others in a crowded yoga class.This mat is also excellent for those wanting to practice yoga at home on carpet. My other mats always slid around on my carpetted floor, but this one is heavy enough to stay put. If you are committed to a yoga practice, invest in this mat and you won't regret it. The only negative is that it is so heavy I would not necessarily recommend it to yogis that walk or bike to class.Namaste!
