FWIW - While visiting the Maldives (and Island Sands) in early December, I finally had a chance to put my new DUI Delta ADV Jacket to the test and I can sum it up in one word - SWEET!
Once I gave up on using the weight belt and actually used the Integrated pockets (yeah, yeah, I know "Why use a belt in the first place with an Integrated BCD _ Answer: because I wasn't sure how much weight I was going to need and it was easier to add weight to the BCD if I already had a fixed amount in the jacket plus it is a REAL pain to get the weights into the pockets once the jacket is on.....) it was great.
Since the majority of the lift is on the back (like a wing), you stay relatively flat in the water BUT, since there is a little bit of lift in the front, you tend to roll face up on the surface (good for not drowning in a bad situation)
Anyway, that is my 2 pennies worth and it has NOTHING to do with a Zeagle Ranger..... rofl
