There's no way I'd ever consider a DUI. Even with Key Man pricing which is stupidly (or wonderfully) aggressive, I wouldn't consider a DUI. I have many friends who dive them. They have several of them each, because they need a drysuit while their other two drysuits are in the shop getting repaired for leaks. Of the nearly 40 DUI suits I'm familiar with locally, none of them are "dry" drysuits 10, 5 or even 2 dives in a row.
But man, they appeal to a certain tech crowd. They buy them like no other suit exists. They even admit that they leak like a sieve. But they still buy them. No thanks.
Me personally.... for my last drysuit (and I've dove all the major brands) I went with a Bare XCS2. It has a lifetime warranty on zippers and seams. It is by far the nicest drysuit I've been in (excluding the $4000 Viking suits I wore in contaminated water). It has been bone dry every dive (about 100 so far). Not a drip of water, regardless of the dive type. Summer salts, loops, and twists on a scooter; bending, climbing, pulling, scraping, not a single drop of water gets by.
It's comfortable and warm. And it's half the price of a DUI. Combine the lifetime warranty vs. 7 year warranty, and it's a no brainer.
