Love this mat!
Color: Pale Green
I love this mat. I use it 5x per week with my strength training, cardio, stretching, whaever workouts. I prefer to be barefoot on it. It’s holding up well and is easy to roll up and store when not in use. I like the size, it gives me enough room to do whatever workout I need to do. The green color is very cute too! I’m 5’3”

Great size, not great traction
Color: Smoky Pink
Absolutely love the size and thickness of the mat. Perfect for Pilates. The traction is not as good as advertised. Definitely still slippery for certain positions. But overall good price for the money.
