If you want to buy yoga mats.Ask yourself:
When I sweat, will the grip remain the same?
Will the mat remain on the floor and not stick to my feet?
Does the lifespan of the mat compare well with others?
Will particles like dust and lint shake off easily?
Is it lightweight for carrying?
Will it hold up to repeated washings?
Would it keep my feet from slipping?
Good yoga mats will last for years and provide better usage, while a cheap mat will degrade your practice.Always get the best quality mat that you can afford.

The pinch test: Pinch the mat between thumb and forefinger to compare compression resistance.
