My 2 1/2 year old son trialed the Conni swim pants today during his learn-to-swim lesson. He thought he looked extra special in his new swimmers and said they were comfy. Being in the pool with my son, I found that the thick wet-suit style material was also great for maneuvering him through all the activities. The built-in undergarment seems to provide more support (and comfort) than other swimmers we have purchased. Definitely a quality product. While my son is now potty trained, I can appreciate how great these pants would be during the potty training process – much more peace of mind!
