Yoga mats can range from the super-thin travel variety that rolls up tightly to take up little room in your suitcase to deluxe versions that cushion you during a soothing therapeutic session. Choosing the thickness level can depend on the type of practice you are looking at completing. Thicker mats can make it more difficult for you to keep your balance and feel with the floor. Harder poses that focus more on balance can be impacted by a thicker mat. While thinner mats can graze your knee during different lunging poses. Generally you should consider the practices you most often train with and how much space you need for your mat when travelling.
