If you are looking for an incredible yoga mat, look no further. Seriously. I have been doing yoga for about 3 years now and have had various mats through that time. Most if not all would always require me to use a knee pad to avoid that pain. A few months back, I bought a cloth top yoga bag, it was huge! I take with me to every yoga class and it is perfect!Well, now I am going on vacation and will not be able to bring the yoga mat that I bought and love. I found this, read some reviews and thought I'd give it a shot with Amazons excellent return policy, how could I lose.I have used this mat about 5 times now and will be putting it through its paces. So far, this thing is incredibly sticky, I DO NOT have to get the top wet (like my cloth one) to stick to it. It just works! I do not need any padding for my knees in various positions. As thin as it is, it is PERFECT to avoid ANY pain in my knees. I take it to work with me in my laptop bag and knock out a quick 45 minute yoga session during lunch in my gym at work. I NO LONGER have to touch the stinky mats that this whole building uses, yuck!As far as weight, I barely notice carrying it. My laptop is heavier. I wish I could give this product 6 stars. I am so glad I found it.As good as this mat is, I am even considering replacing my larger one with this one. Its that good! My next tests will be taking it to the beach and see how well it does with sand and then getting a rinse.Pros:- Sticky, I don't slip on the mat- Doesn't move- Doesn't slip on the floor- Perfect size for me (5' 9") - I bought the long one.- Small size (when rolled up)- Fits in my laptop bag- Not heavy at all, will be perfect for travelling- Great for taking on my bike- Folds up so the side I use for yoga NEVER touches the ground (EXCELLENT IDEA).Cons:- Stinks, I washed and aired it out. (not a show stopper)You can see in the pictures the size. Its half the size of my laptop. You can also see it next to my foot (size 10 shoe).Taking it to the beach is next, we'll see how well it handles sand.
