Excellent Goggles — Comfortable, Secure, and No Leaks
Color: Aqua
These goggles are excellent quality and were very easy to adjust. They have good suction and fit nice and tight without being uncomfortable and stayed secure the entire time I was swimming. Not much for style, but these do look pretty cool. I wore them for about an hour with no issues at all—they remained comfortable and didn’t leak, which is a huge plus. The seal held up well without leaving painful pressure marks. The included case is also a great bonus and makes storage and travel easy. Overall, a very solid pair of goggles that perform exactly as expected. Definitely recommend.

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.
