This tube between the eyes takes getting use too. I've always used side tubes.

I had never tried one of these. It works but snorkels with a drain are better I found out. Fills with fluid pretty quickly.

great product

This has been the best fitting, most comfortable centerline snorkel that I have tried so far, probably due to the various ways to adjust the fit. I do find myself re-tightening straps during extended snorkel sets, though. Also, the option to purchase a replacement mouthpiece alone would keep me from looking at different manufacturers for my next snorkel. I tend to go through mouthpieces way too quickly to repeatedly buy complete snorkels just for a new mouthpiece. Come on, Speedo, how about selling replacement mouthpieces!?

My neck and overall work out has greatly improved. I am not the only one wearing a snorkel in the lap pool - has made the workout effective.
