Harness for bigger guys?
 

So, I'm looking into Harnesses and I was wondering if most of them allow bigger guys to fit in them.
I have a 42 inch waist and weigh about 280. (Working on it LOL)
Is there a specific set that allow for bigger guys?

I was also looking into the Cipher 4 point 2 inch Camlock set.
Anyone have experience with those, along with the Cipher harness bar?
Are they safe?

Thanks,

First, why are you wanting harnesses?
Second, what seats are you running?
Third, what is your harness bar/cage situation? Do you have HANS?
Fourth, You do not want 4 points, unless they have the built in Anti-Submarine Tech(I've only seen Scroth with it).
