Rating: Lived up to reputation

Like the description, the snorkel remained dry and easy to use. Dived under the surface several times without getting mouthfuls of water.

Rating: Great boots

Very durable and comfy. Proved their worth on some rock where they would not be pierced and had great traction.

Rating: Fantastic Backpack

This backpack was great. It made two airline trips without a hitch. It is very spacious and very tough. It held two sets of gear with some room to spare. And the straps make it an easy carry. I am very glad I bought it and plan on using it a great deal in the future.

Rating: nice and comfy

these feel good, they are thin and the soul is not great for rocks. my only gripe is the rubber needs to come over the toes

Rating: 1st set of fins seem vey solid

these were my first set and they are easy to swim with, the foot pockets are large so a thicker bootie is needed

Rating: seals good no leaks

I have a small face and this mask seals and does not leak over all very happy
