This is a nice mat for floor exercises.
Color: Aqua, Style: 1-Inch
I had some lower back issues and went to physical therapy. I used this mat for my floor stretches and exercises at home along with my big rubber ball. It made the floor work so much more comfortable. Beware of the smell. When I unroll it I still smell that “memory foam” odor, which takes some getting used to. I aired it out as instructed, twice, and it persists. It’s a wonderful mat so the odor is not a deal breaker. I’d buy it again.

Maximum joint comfort and durability
Color: Pink, Style: 1/2 Inch
I absolutely loved the color, and it offers incredible cushioning without sacrificing stability during balance poses. It is dense, doesn't lose its shape, and springs back instantly. The materials are high-quality, and it doesn't have that strong plastic smell that others often have. It is worth every penny for the comfort it provides.

These sunglasses are such a great combination of style, comfort, and value.
Color: Going to Valhalla...witness\!, Color: Going to Valhalla...witness\!
I absolutely love these sunglasses. They’re lightweight, comfortable, and fit perfectly without constantly sliding down your face. The medium-sized frame is super flattering and works well for both workouts and everyday wear, which honestly makes them one of the most versatile pairs I own. The polarized lenses do a great job cutting glare, especially for driving, beach days, walks, and outdoor activities, and I appreciate that they still feel stylish instead of overly sporty. The quality is impressive for the price point, and they’re durable enough that I don’t panic about bringing them on trips, hikes, boat days, or throwing them in my bag. They’ve definitely become my go-to sunglasses for everything from walking the dog to vacations to casual everyday errands. Cute, functional, affordable, and surprisingly high quality.

Impressed! Perfect for summer
Color: Phoenix at a Bloody Mary Bar V3
These sunglasses are spectacular, i am very impressed for the price point. Affordable, good quality, lightweight, and fit perfectly! I have very sensitive eyes, so I have to be very picky about the sunglasses I wear, usually having to spend $$ for a good pair. These pass the test, at a fraction of the cost. The lenses are polarized and block the sun fairly well. Wore these on a walk as soon as I bought them, and I am already wanting to buy another pair!! definitely recommend, if you are looking for something that is sleek, but fun. Can also be a great gift!! Love the variety of color options!

Great quality, durable, and stylish
Goodr are some of the best sunglasses you can buy at this price point, whether you’re an athlete or just want them for casual use. I love the matte black finish, which is just a touch lighter than my own soul :). The polarization and general glare reduction have been great on extra sunny days. I recently dropped them from my head on concrete or asphalt, and even though a lens popped out, I was able to get it back in place with quite a bit of effort - which is good, because I’m still confident it won’t pop out easily. There was only some minor scratching on the frame that mostly wiped off but it held up just fine, so +1 for durability!
