I usually dive the Caribbean twice a year. Once in the winter on a cruise with some friends in Jan wearing a skin and a 3mm jumpsuit and with our dive club in summer with a skin and a 3mm shorty. I wear my Henderson lycra skin for sunburn and scratch protection.

With this skin, I can forgo the shorty wetsuit during the summer diving and still have a degree of warmth as well as protection from the sun and scratches. I would buy it again without hesitation. If I had known about it, I would probably bought it instead of the regular lycra skin and used it year-round.

Nice to have a knife that wont rust in salt water.

Got these fins about a month ago. I have used them on 30 dives so far. They have made my dives much easier and make turning and manurvering very easy

Purchased these boots for my open water class. My feet stay very warm in the cold waters of the Puget Sound here in Seattle, WA. Well made boots!

this skin is perfect not only to wear under a wetsuit for ease to put on your wet suit, but also its a perfect snorkeling suit when you want something lightweight and to keep the sun off of you.

I had been looking for quite awhile for a regulator bag and this was such a bargain price. Fits not only the regulator but room for other stuff. Would highly recommend

Not loud enough. Could hardly hear it myself.
