I have the TLS350 as well. Mine is the front zipper, self donning..... right!! It is a challenge getting out of it but I manage, but trying to get the right arm in when putting on the suit is nuts. CanÃÕ do it by myself at all! To get out of the suit, I start with my right arm and keep working it out. Takes a bit of doing. Hay, I am looking for a dive buddy. I live in Corona, Ca. and dive mainly in Laguna Beach, Crescent Bay. My dive buddy for over 13 years moved out of state. I am 60 and other hobbies are weight lifting and body conditioning. I go every weekend, water permitting. I like AM dives before all of the students mess up the water. Interested? IÃÎ under Carl Randall
