Initial Review: My previous mat (Lulu's The Mat reversible) was taken out of my car.  As I practice daily, I needed a mat to stand up to rigorous use and I like the idea of a lifetime guarantee.  After much reading and the recommendations of various people, I settled on the Manduka Pro.  In the intervening days, I was borrowing a Manduka Pro Light, so I knew sort of what I was getting.

There has been much made about the film and initially slipperiness. I got my mat and followed Manduka's seasoning instructions prior to my first practice. It was by no means slippery.  It may not have been quite as sticky/grippy as the pro lite I was borrowing, but that was an old broken in mat.  So, I look forward to the grip improving with time.  Comparison of the grip from the first practice, it was probably tackier than the Lulu when not sweating and only a little less so than the Lulu when sweating.

The firm material density provides excellent cushioning for the knees/head/etc.  when flowing in an active practice, possibly a little superior to The Mat on this count.

If you've ever had your Lulu mat slide across the studio floor... well Maduka will absolutely not do that.  The grip on the floor is a relief after many years of a mat that slides.

I'm anxious to get this mat outside for outdoor practice and see how it holds up.  Since I practice outside most of time during the warm weather months, a Jade was not preferable since they degrade in sunlight.

Weight: this is not light mat.  But then again, I can thunk someone with it if necessary, so I consider that a bonus.  I'm not walking miles to practice, so it works for me.

Overall - I'm happy with my mat after first practice and I have every reason to believe it will get better and better over time.  I still miss my lulu, but maybe only because I didn't get to say goodbye on my own terms.
