Question: How well does this towel work for Ashtanga?
Document: This works but I prefer the YogaRat 100% Microfiber HOT YOGA TOWELS. They are thicker and more plush for HOT yoga sessions. I purchased 2 of the thicker ones as this one I found to be a bit on the thin side. Works well though if you have a thicker yoga mat so I still give this 4 stars. I do recommend wetting the towel before class as the color of the mat is noticeably different between wet and dry stages. I found my sweat prints to be distracting during the class.
I'm glad I bought 2 of these. They work perfectly. I only use them dry - and they're very inexpensive.
I like hot flow vinyasa classes, but now living in AL, I find that my wonderful BIG BLACK MAT simply gets too wet in the humidty of the Deep South, so I ordered this to help and it works very well!
This is the perfect wipe-down yoga towel. It's small, compact, and highly absorbent. I highly recommend it to any hot style yoga practitioner.
The small towel is the perfect size for when I need it most (down dog), and I can push it aside when I don't need it. But now I want every color.
It dries quickly- so I'm not constantly wiping my face with a wet towel. I also use it over a block to keep my head comfortable and the block a little cleaner. Works great!
This towel is the perfect size for the gym (I bought the smaller option). It soaks up sweat for the entire workout. I gave it 4 stars instead of 5 because you can't really wipe the sweat away so much as blot it away which is annoying when running. Otherwise, this was a great purchase.
I bought the hand towel and the mat towel:Mat towel:I'm new to yoga and I spent my first few classes slipping and sliding all over my mat. I started looking for something to help- and the reviews for the YogaRat towel seemed overly positive. I bought it- and it's perfect! The length is just perfect to cover the mat. As others have said, if it moves during practice, it's easy to readjust. It dries quickly- which is great!
Very happy with the texture and absorbency of the mat and hand towels. Makes hot yoga much more pleasurable. Others in classes have asked about them, and I'm happy to recommend the Yoga Rat products.
This mat is AMAZING and I can now concentrate on my practice instead of slipping around all over the place during hot yoga or bikram classes. The BEST money I have EVER spent!
