It was amazing. I read reviews prior and many stated they thought it was too constructive, especially the neck. It was tight, but I didn’t find it that uncomfortable. I definitely didn’t want the cold water to enter! When prepping for it, be sure to wear a base layer - no bathing suit required. I definitely recommend this experience!

Good stuff
The experience was like nothing we’d ever seen. Water was crystal clear and the water scape was awesome to look at. Our tour guide Abby was awesome and made the experience even more fun. Would definitely go again!
