over 1+ years use and it’s still great quality 😩
Color: Violet Haze, Size: 1 inch
have had this mat since june 2024 and it’s still in amazing quality!! it’s so comfy, thick and soft which is why i bought it. i feel like i could use this thing on a rocky ass ground and i wouldn’t feel anything but squishy-ness lol so protection is so good. the color is still vibrant too (i got the lavender color) which i love!! really makes such a huge difference in my energy when i workout, making me feel like dat gooorl 👏🏼 i’m 5”2’ so there’s ample space for me. definitely slip resistant, im able to perform lunges with one leg on and off. also love the band you can wrap around it so you can transport it anywhere :) just purchased a black one for my hubby which is why i’m here again hehe
