Hi I want to invest in a wetsuit and was wondering about the differences between a onepiece or two. It kinda seems like more and more people and companies are moving towards 2 piece wetsuits. I was wondering what the advantages and disadvantages of both are. Ive only used a one piece before but it seems like it would be easier to get into a one piece than two. Whats the advantage of haveing a real slick inside(i think its called open cell???) and a regular neoprene outside. Any good brands that you guys know of. Thanks in advance
