I bought this suit to aid in my 5K open water swim during an early fall event.  After reading the advantages of such a product for warmth and buoyancy, I found all claims to be accurate.  Swimoutlet overnighted this item to make sure I had it on time; it arrived early; it helped me come in with 14 minutes off my best time.  It is made of quality, durable material and is most flexible in the upper body regions to allow freedom of stroke movement.  I will wear it in future events and in training especially in colder water temps.  Special thanks to the customer service folks at Swimoutlet for helping me receive this product on time.  You have earned my future business.
