My son ended up getting one of these in demo after having ride-up issues with his Dakine Pyro harness. He ended up settling on the non-carbon version since it's really supportive but doesn't press in on his sides or back like the carbon (he's skinny and twiggy, so this one just suited his body type the best). I tried one out myself in the shop, but they don't come in 2XL, but this harness will let you customize it like crazy. The ratchet system is simply the best. I don't mind regular strap style, but these are next level. The best part about going to Real is they've got just about everything in there, so you can try them on or get something in the rental shop to test instead of gambling on a few seconds of fitting out of the water.
These may seem a little pricey, but the spreader is included, so it almost evens out with a regular harness. Maybe it's slightly more premium in price, but dude, it's worth it!
