Hard Nose Bridge
Color: Blue-black
They seem like nice goggles. I would echo what others have said: The nose bridge is made of hard plastic with two little bumps on each side (conceivably to snap the lens into the nose bridge) that very well may press into your nose, making the goggles uncomfortable to wear. I would look for a pair with a soft nose bridge. I previously owned a pair of Aegend swim goggles with a soft nose bridge that I liked.

Totally worth the price!
Color: Lagoon, Style: 2 Blocks
These are great blocks! They are soft yet supportive. Used for yoga, Pilates and on the sits-bones when meditating. All purpose, perfect size, cute, calm color. I have two sets, I like them so much; one for the house and one in the gym.

Highly Recommend Gaiam Yoga Blocks
The Gaiam yoga blocks are excellent quality and a must-have for any yoga practice. They’re lightweight yet very supportive, making it easy to maintain proper alignment and balance in a variety of poses. The foam is firm but comfortable, with a non-slip surface that stays in place during practice.
These blocks are especially helpful for stretching, improving flexibility, and modifying poses, whether you’re a beginner or more experienced yogi. They’re durable, easy to clean, and hold their shape well over time.
Overall, Gaiam yoga blocks offer great value and reliability. I would definitely recommend them to anyone looking to enhance their yoga or stretching routine. 🧘♀️✨
