The Warrior II is an awesome choice, I have the black, white and red one and am completely happy with it. It's a little more rigid than most harnesses but I like that, and the side cutouts (dips) that transition from the back to the ribs help a lot with comfort and rotations. Also no issues like with previous years with chafing when no rashie is worn. I would recommend buying from a reputable local dealer as the new clicker bar spreader bar has some issues with coming undone. I have had mine replaced I wish they stayed with the old system. As for a handle pass leash, the Len10 color scheme is the only one that comes with the handle pass leash but I believe is more expensive, so you can get any color scheme and buy the handle pass leash separate and it works out to the same price.
And I agree that if that's all you wore when giving it to him it would be a memorable harness
