I’d always underestimated the Pyro Lite until I tried one last year as I’d sold my own Pyro Pro. It’s a really comfy and flexible suit and as warm as the Pyro Pro. It’s made from the same 200 denier nylon that makes up the majority of the Pyro Pro but lacks the breathability and butt and knee reinforcement of the more expensive suit. Being of a simpler panel layout it lacks some of the style of the Pro but it’s still way more stylish than your average dingy suit.
To address the potential wear issues a cheap pair of kite pants would do the job although I doubt you’d need them as the suit is designed to take the abrasion of a harness and of course the occasional drag up the beach.
Try it, you won’t be disappointed.
