I have a Mares Vector 1000 Air Trim that I have dove for over a year in fresh and salt water. I volunteer as a Public Safety Diver and have found this BC to be great for regular recreational diving as well as having lots of D rings and pockets large enough to house items I need for PSD. The material is tough nylon and has held up great from all the dives I have put it through (fresh, salt, rope searches, etc) my only complaint is that it is a little heavy overall, makes for a little trouble when traveling. However I was able to fit all my dive gear in a rolling duffel bag last November to Mexico and make 45 lbs. It is a great BC and will hold up well, if you have the choice I would definitely recommend the Air Trim, super convenient and works great.
